The first human West Nile Virus infection in Orange County this season reported

Posted on September 23, 2021 by Editor Posted in Disease, Health and Medical, Insects, Orange County, Orange County Vector Control District Leave a comment

A Buena Park woman was diagnosed last week with West Nile Virus (WNV) infection, and was hospitalized but is recovering. This is the first human WNV infection identified in Orange County this season. As of Friday, the California Department of Public Health has reported 46 cases of human West Nile Virus infections statewide this season, including three in Los Angeles County.

West Nile virus (WNV) is the leading cause of mosquito-borne disease in the continental United States. It is most commonly spread to people by the bite of an infected mosquito. Cases of WNV occur during mosquito season, which starts in the summer and continues through fall. There are no vaccines to prevent or medications to treat WNV in people. Fortunately, most people infected with WNV do not feel sick. About 1 in 5 people who are infected develop a fever and other symptoms. About 1 out of 150 infected people develop a serious, sometimes fatal, illness.

The incubation period is usually 2 to 6 days after a bite from an infected mosquito. Most symptomatic WNV cases have an acute febrile illness. Symptoms also include headache, malaise, arthralgia, or myalgia, and occasionally nausea, vomiting and/or a maculopapular rash. About 1 in 150 WNV-infected persons develops neuroinvasive disease, which can manifest as encephalitis, aseptic meningitis, acute flaccid paralysis, and/or transverse myelitis.

Testing for WNV: Testing for WNV should include serum WNV IgM and IgG, with CSF IgM when a lumbar puncture is performed. Because serum WNV IgM may be negative early in the course of disease, repeat serology may be indicated if initial testing was done within 8 days after the onset of illness.

Health care providers should consider WNV infection in patients with prolonged fever or acute neurologic illness.

Surveillance of West Nile Virus in the community: Report all WNV infections to Orange County Public Health by phone (714-834-8180) or fax (714-564-4050) within 1 working day. For more information on mosquito surveillance and control activities, please visit the Orange County Mosquito and Vector Control District website at http://www.ocvector.org/.

Avoiding mosquito bites is the best way to prevent WNV infection:
Eliminate standing water which can serve as mosquito breeding sites around the home or workplace.
Ensure windows and door screens are in good repair.
Use an insect repellent containing active ingredients registered with the U.S. Environmental Protection Agency when outdoors. Active ingredients include DEET, picaridin, and oil of lemon eucalyptus. Natural bug sprays may not be effective against mosquitoes. For more information, visit http://www.cdc.gov/westnile/faq/repellent.html.

Mosquitoes carrying West Nile virus have been found in Santa Ana

Posted on September 23, 2021 by Editor Posted in Disease, Insects, Orange County Vector Control District, Santa Ana Leave a comment

Mosquitoes carrying West Nile virus have been found in Santa Ana, according to the Orange County Mosquito and Vector Control District. Now more than ever it is important to check your outdoor spaces for standing water to prevent mosquitoes from breeding and spreading this disease.

Mosquitoes breed in even tiny amounts of standing water, such as in plant saucers, bowls, cups, fountains, tires, barrels, vases, and other containers. Take precautions outdoors and wear mosquito repellent when mosquitoes are most active (at dawn or dusk.)

Remember: Tip, Toss + Take Action!

Tip standing water weekly
Toss unneeded containers
Take action + apply repellent to exposed skin when outdoors

The first West Nile Virus positive mosquito sample of the year has been identified in Orange County

Posted on August 12, 2021 by Editor Posted in Disease, Fullerton, Health and Medical, Orange County, Orange County Vector Control District Leave a comment

Orange County’s first West Nile Virus (WNV) positive mosquito samples of the season were identified last week in Fullerton through routine trapping and testing by the Orange County Mosquito and Vector Control District (OCMVCD).

NV positive mosquito samples have been identified in Los Angeles, San Bernardino and Riverside County this year.

St. Louis encephalitis virus (SLEV) was detected in five mosquito pools in Riverside County last week for the first time in 2021.

One human case of WNV was reported two weeks ago from Los Angeles County.

No human infections of WNV or SLEV have been identified so far this season in Orange County.

West Nile virus (WNV) is the leading cause of mosquito-borne disease in the continental United States, according to the CDC. It is most commonly spread to people by the bite of an infected mosquito. Cases of WNV occur during mosquito season, which starts in the summer and continues through fall.

There are no vaccines to prevent or medications to treat WNV in people. Fortunately, most people infected with WNV do not feel sick. About 1 in 5 people who are infected develop a fever and other symptoms. About 1 out of 150 infected people develop a serious, sometimes fatal, illness.

You can reduce your risk of WNV by using insect repellent and wearing long-sleeved shirts and long pants to prevent mosquito bites.

Garden Grove man the first to die of the West Nile Virus in the O.C. this year

Posted on September 16, 2020 by Editor Posted in Disease, Garden Grove, Health and Medical, Insects, OC Health Care, Orange County Vector Control District, Santa Ana Leave a comment

(Santa Ana, CA) – The first human death associated with West Nile virus (WNV) infection in Orange County has been confirmed this week by OC Health Care Agency officials. The case is an elderly male resident of Garden Grove who died with WNV infection complications.

Orange County has had 5 symptomatic WNV infections reported this year. Two had WNV neuroinvasive disease and three had WNV fever; of these, four were hospitalized. Because about 80% of people infected with WNV have no symptoms, and the majority of cases of West Nile fever do not seek medical care and are not tested, the reported case counts greatly underestimate the number of infected people in Orange County.

Symptoms of West Nile fever include fever, headache, body aches and fatigue. Anyone who develops the more serious symptoms of West Nile neuroinvasive disease such as severe headaches, neck stiffness, confusion, muscle weakness or vision loss should seek medical care immediately. People over 50 years of age and those with underlying medical conditions are at increased risk of serious complications from West Nile virus infection.

It is especially important to take precautions against mosquito bites during West Nile virus season. Recommended precautions include:

Recommended WNV precautions include:

• Emptying all standing water on your property to reduce areas in which mosquitoes may breed, including flower pots and pet bowls
• Making sure your window and door screens are in good condition
• Using insect repellent containing DEET, picaridin, oil of lemon eucalyptus, or products containing IR3535, always following label directions
• Limiting outdoor activity at dawn and dusk, when mosquitoes are most active
• Wearing long-sleeved shirts and long pants when outdoors

Information on mosquito control is available on the Orange County Mosquito and Vector Control District’s website at www.ocvector.org. Other websites with helpful information about WNV include:

First human West Nile Virus infection of 2020 reported today

Posted on August 10, 2020 by Editor Posted in Disease, Health and Medical, Insects, OC Health Care, Orange County, Orange County Vector Control District, Santa Ana Leave a comment

(Santa Ana, CA) – A child under the age of 18 years was diagnosed last week with West Nile Virus (WNV) infection, and was hospitalized but is recovering. This is the first human WNV infection identified in Orange County this season. As of Friday, the California Department of Public Health has reported 10 cases of human West Nile Virus infection statewide.

In 2019, there were seven reported human infections of WNV and one WNV-related death reported in Orange County. Most people who become infected with WNV do not experience symptoms, but about 20% will develop fever and may have headache, body aches, nausea, tiredness and sometimes a skin rash. More serious symptoms, such as severe headaches, neck stiffness, confusion, muscle weakness or paralysis, occur more rarely, but people who develop these symptoms should seek medical care immediately. People over 50 years of age and those with certain medical conditions are at increased risk of serious complications from WNV infection.

“West Nile Virus is endemic in Orange County, recurring every year during the summer months and continuing into the fall,” said Dr. Clayton Chau, Acting County Health Officer. “The best way to avoid West Nile Virus infection is to take precautionary measures to avoid mosquito bites.”

Recommended WNV precautions include:

West Nile Virus activity has already been identified in county mosquito populations this season. Information on mosquito control is available on the Orange County Mosquito and Vector Control District’s website at www.ocvector.org. Other websites with helpful information about WNV include:

First West Nile Virus positive mosquitoes confirmed in Orange County this year

Posted on July 9, 2020 by Editor Posted in Anaheim, Disease, Garden Grove, Irvine, Orange County, Orange County Vector Control District Leave a comment

Garden Grove, CA. The Orange County Mosquito and Vector Control District (OCMVCD/District) has confirmed that mosquito samples in three cities have tested positive for West Nile virus (WNV). These are the first samples to test positive in the county this year. The positive mosquitoes were collected on July 7, 2020 in Cypress at Cerritos Ave and Lexington Dr, in Anaheim at E. Sycamore St. and East St. and in Garden Grove at Garden Grove Blvd and Stafford St. The District has also confirmed that one dead bird with WNV was collected in Irvine.

“West Nile virus positive mosquito samples indicates that the virus is active in Orange County and there is an increased risk for residents to become infected with WNV through a mosquito bite.” Said Robert Cummings, Director of Scientific Services.

West Nile virus is most commonly spread to people by the bite of an infected mosquito. Mosquitoes become infected when they feed on infected birds. There are no confirmed cases of human infections currently in Orange County.

The Orange County Mosquito and Vector Control District staff will continue to conduct surveillance, inspections, and control measures for mosquitoes in the areas to prevent additional mosquito breeding. OCMVCD will post WNV advisory signs alerting residents of high WNV activity in the affected areas.

“It is essential for residents to do their part and take charge of their yard,” said Lora Young, Director of Communications. “The best way to protect yourself is by applying EPA-registered repellent, wearing long sleeved clothing and eliminating potential breeding sources around your property.”

Muchos mosquitoes in Orange County!

Posted on June 26, 2020 by Editor Posted in Disease, Insects, Orange County, Orange County Vector Control District, Santa Ana Leave a comment

The Orange County Mosquito and Vector Control District (OCMVCD) is observing an increase in mosquito activity in urban and coastal areas of the County. This increase marks the sixth week in a row that OCMVCD has recorded higher than average counts. Mosquito collections at this time last year averaged 24 mosquitoes per trap. This year, however, the District’s traps have caught an average of 110 mosquitoes per trap, an increase that is nearly five times higher than last year’s numbers. As shown in the graph, this year’s mosquito counts are double the County’s 5-year average.

“High mosquito abundance is one factor that increases the risk for West Nile virus (WNV) transmission when virus activity is present. However, OCMVCD currently has not detected any WNV in our surveillance program,” says Robert Cummings, Director of Scientific Services.

Three surrounding counties (Los Angeles, Riverside, and San Diego) have detected West Nile virus in their mosquito samples. This early season virus activity in the region is concerning when coupled with high mosquito abundance.

Based on the high mosquito population in areas of Orange County, the District has implemented additional outreach to residents and will continue to identify and treat any water sources that result in mosquito breeding. It is essential for all residents in Orange County to be active in eliminating mosquito breeding in and around their properties to help reduce the number of adult mosquitoes.

Residents should take the following precautions to help reduce the chances of breeding mosquitoes:

• Dump and drain any containers filled with water at least once a week
• Clean and scrub bird baths and pet water bowls weekly
• Do not transport or share plant clippings rooted in water
• Drill a hole or puncture containers to eliminate standing water

To prevent mosquito bites, take action, and follow these tips:

• Apply mosquito repellents to exposed skin before going outdoors
• Wear repellent containing DEET®, Picaridin, IR3535, or oil of lemon eucalyptus
• Close all unscreened doors and windows to prevent mosquitoes from entering your home or space; repair broken or damaged screens
• Wear long-sleeved shirts and long pants, and opt for lighter-colored clothing

La Alta Abundancia de Mosquitos Causa Preocupación en el Condado de Orange

(NOTA: Este comunicado de prensa fue proveído por el Distrito de Control de Mosquitos y Vectores del Condado de Orange.)

El Distrito de Control de Mosquitos y Vectores del Condado de Orange (OCMVCD) está observando un aumento en la actividad de mosquitos en áreas urbanas y costeras del Condado. Este aumento marca la sexta semana consecutiva que OCMVCD ha registrado conteos más altos que el promedio mensual. El año pasado el número de mosquitos coleccionados en este tiempo tuvo un promedio de 24 mosquitos por trampa. Este año, las trampas del Distrito han atrapado un promedio de 110 mosquitos por trampa, un aumento que es casi cinco veces más que las cifras del año pasado. Como se muestra en el gráfico, el recuento de mosquitos de este año es doble el promedio de los últimos 5 años en el Condado.

“La alta abundancia de mosquitos es un factor que aumenta el riesgo de transmisión del virus del Nilo Occidental (West Nile Virus: WNV) cuando hay actividad viral. Sin embargo, OCMVCD actualmente no ha detectado WNV en nuestro programa de vigilancia,” dice Robert Cummings, Director de Servicios Científicos.

Tres condados circundantes (Los Angeles, Riverside y San Diego) han detectado el virus del Nilo Occidental en sus muestras representativas de mosquitos. Esta actividad del virus a principios de la temporada en la región es preocupante cuando se combina con una alta abundancia de mosquitos.

Basado en la alta población de mosquitos en las áreas del Condado de Orange, el Distrito ha implementado actividades de divulgación adicionales para los residentes y continuará identificando y tratando cualquier fuente de agua que resulte ser criadero de mosquitos. Es esencial que todos los residentes del Condado de Orange participen activamente en la eliminación de sitios de crianza de mosquitos dentro y alrededor de sus propiedades para ayudar a reducir la cantidad de mosquitos adultos.

Los residentes deben de tomar las siguientes precauciones para ayudar a reducir las posibilidades de criar mosquitos:

• Vacíe los contenedores llenos de agua al menos una vez a la semana.
• Limpie y friegue los baños de aves y cuencos de agua para mascotas semanalmente
• No transporte ni comparta recortes de plantas enraizados en agua.
• Taladre un hoyo o perfore los contenedores para eliminar agua estancada.

Es escencial prevenir las picaduras de mosquitos, OCMVCD ofrece los siguientes consejos:

• Apliques repelentes de mosquitos a la piel expuesta antes de salir al aire libre.
• Use repelente que contenga DEET®, Picaridin, IR3535, o aceite de eucalipto de limón
• Cierre todas las puertas y ventanas sin mosquiteros para evitar que los mosquitos entren a su hogar o espacio; repare los mosquiteros rotos o dañados
• Use camisas de manga larga y pantalones largos, y opte por ropa de colores más claros.

Remove standing water to prevent mosquitoes and prevent disease

Posted on May 11, 2020 by Editor Posted in Disease, Insects, Orange County, Orange County Vector Control District, Santa Ana Leave a comment

Rain creates an opportunity for mosquitoes to thrive and breed in standing water. More rainfall generates more pools of water, which increases the number of mosquitoes. Just one small bottle cap of water can result in hundreds of mosquitos.

In order to prevent mosquito breeding, we ask everyone in the community to help in the fight against mosquitoes by eliminating their favorite places to breed and lay eggs. Please check your yard on a regular basis and remove any temporary pools of water.

The Orange County Mosquito and Vector Control District offers the following tips to prevent mosquito breeding:

• Dump and drain any containers filled with water at least once a week.
• Clean and scrub bird baths and pet water bowls weekly.
• Dump water from potted plant saucers, cans, old tires, jars, buckets, barrels, tubs and tarps covering outdoor equipment.
• Do not transport or share plant stems rooted in water.
• Drill a hole or puncture containers to eliminate standing water.

The Orange County Mosquito and Vector Control District has suspended all in-person consultations and property inspection appointments until further notice. However, residents can still submit a tip for out-of-service pools, ponds and large breeding sources here: www.ocvector.org/submit-a-tip

Elimine el Agua Estancada para Prevenir los Mosquitos

La lluvia crea una oportunidad para que los mosquitos prosperen y se reproduzcan en agua estancada. Más lluvia genera más charcos de agua estancada, lo que aumenta la cantidad de mosquitos. Con solo la cantidad de agua que cabe en la tapa de una botella de agua se pueden crear cientos de mosquitos.

Para evitar la cría de mosquitos, le pedimos que por favor revise los alrededores de su casa y elimine cualquier agua estancada.

El Distrito para el Control de los Mosquitos y Vectores del Condado de Orange (Orange County Mosquito and Vector Control District) ofrece los siguientes consejos para prevenir la cría de mosquitos:
• Vacíe recipientes llenos de agua al menos una vez por semana.
• Limpie y friegue los baños de aves y el tazón de agua para mascotas semanalmente.
• Vacíe el agua de los platillos de plantas en macetas, llantas viejas, frascos, barriles, tinas, lonas que cubren equipos de exterior y cualquier otra cosa en donde se estanca el agua.

First O.C. mosquitoes test positive for the Saint Louis Encephalitis virus

Posted on October 17, 2019 by Editor Posted in Anaheim, Disease, Health and Medical, Insects, Orange County Vector Control District, Westminster Leave a comment

Garden Grove, CA. The Orange County Mosquito and Vector Control District (OCMVCD) has confirmed the first mosquito samples to test positive for Saint Louis encephalitis (SLE) in Anaheim and Westminster. The mosquitoes were collected from Old Bolsa Chica Road in Westminster and in the area of Dale Ave and Orange Ave in Anaheim. OCMVCD has not seen SLE positive mosquito samples in these areas since 1987. OMCVCD staff will conduct additional mosquito surveillance and canvass the area to look for additional mosquito breeding sources.

“This is the first detection in these areas in three decades. We are encouraging residents to take the necessary precautions to keep themselves and their families safe. The best way to protect yourself from mosquito bites is to discard any standing water around your home to eliminate potential breeding sources,” said OCMVCD Public Information Officer, Heather Hyland.

Saint Louis encephalitis (SLE) is a viral disease spread to people by the bite of an infected mosquito. Most people infected with SLE virus have no apparent illness. Initial symptoms of those who become ill include fever, headache, nausea, vomiting, and tiredness. Severe neuroinvasive disease (often involving encephalitis, an inflammation of the brain) occurs more commonly in older adults. In rare cases, long-term disability or death can result. There are no vaccines to prevent nor medications to treat SLE. There are no confirmed cases of human infection at this time in Orange County.

Residents should take the following precautions to help reduce the chances of getting bitten by mosquitoes:
• Dump and drain any containers filled with water at least once a week
• Clean and scrub bird baths and pet water bowls weekly
• Dump water from potted plant saucers
• Do not transport or share plant stems rooted in water
• Drill a hole or puncture containers to eliminate standing water
To prevent mosquito bites, the District offers the following tips:
• Apply mosquito repellents to exposed skin before going outdoors; reapply as recommended
• Wear repellent containing DEET®, Picaridin, IR3535, or oil of lemon eucalyptus
• Close all unscreened doors and windows to prevent mosquitoes from entering your home or space; repair broken or damaged screens
• Wear long-sleeved shirts and long pants, and opt for lighter-colored clothing

Truck mounted mosquito spraying set for Sep. 14, 16 and 18 in Santa Ana

Posted on September 12, 2019 by Editor Posted in Disease, Environment, Insects, Orange County Vector Control District, Santa Ana Leave a comment

The Orange County Mosquito and Vector Control District (OCMVCD) isreporting an elevated level of invasive Aedes mosquitoes and an increased risk of mosquito borne disease in areas of Santa Ana. A truck-mounted mosquito control application is scheduled for September 14, September 16 and September 18 from 3:00 AM – 5:00 AM to decrease the adult mosquito population and lower the risk of potential disease.

The applications will occur between Edinger to Occidental and from Lowell to Van Ness [see attached maps]. Application dates and times may change due to weather, environmental conditions or other operational needs. Residents can check the spraying schedule and determine whether their homes are located within the treatment area here.

Residents in treatment areas will be notified prior to the treatment date with door flyers left at their homes. All control products used by OCMVCD are registere d by the federal and state Environmental Protection Agency for the purpose of controlling mosquitoes and protecting public health. The products are applied according to the label rate (less than 1 fluid ounce per acre) and are not harmful to people or pets, even if they are present during the application.

The application will also not harm the finishes on cars or homes. Residents do not have to turn off air-conditioning units during the application. These non-native and aggressive day-biting mosquitoes are black and white and lay their eggs along the waterline of containers as small as a bottle cap. The mosquitoes known as Aedes aegypti (yellow fever mosquito), Aedes albopictus (Asian tiger mosquito), and Aedes notoscriptus (Australian backyard mosquito) are capable of transmitting debilitating viruses including dengue, chikungunya, yellow fever, and Zika. While these viruses are not currently being transmitted locally, transmission could begin if someone infected abroad returns to Orange County and is bit by the invasive mosquito. These mosquitoes are also known to transmit dog heartworm to dogs and cats. Vector Control officials are urging residents to take the necessary precautions to reduce mosquito breeding and to avoid bites from these aggressive ankle-biters.
“Residents must do their part to check their yard regularly and eliminate standing water and water-holding containers” said Lora Young, Director of Communications.

Mosquito control is a shared responsibility and residents need to take an active role in removing water sources and sharing information with their neighbors to help in controlling mosquitoes.

Residents should take the following precautions to help reduce the chances of getting bitten
by mosquitoes:
• Dump and drain any containers filled with water at least once a week
• Clean and scrub bird baths and pet water bowls weekly
• Dump water from potted plant saucers
• Do not transport or share plant stems rooted in water
• Drill a hole or puncture containers to eliminate standing water
To prevent mosquito bites, the District offers the following tips:
• Apply mosquito repellents to exposed skin before going outdoors; reapply as recommended
• Wear repellent containing DEET®, Picaridin, IR3535, or oil of lemon eucalyptus

First mosquitoes test positive for the West Nile Virus Activity in the O.C. this year

Posted on August 5, 2019 by Editor Posted in Disease, Health and Medical, Insects, Orange County, Orange County Vector Control District, Public Safety, Santa Ana Leave a comment

Garden Grove, CA. The Orange County Mosquito and Vector Control District (OCMVCD) has confirmed the first mosquito sample to test positive for West Nile virus (WNV) in 2019. The mosquitoes were collected from the city of Orange at El Camino Real Park on July 30, 2019. The District has also confirmed 9 birds with West Nile virus in the cities of Cypress, Buena Park, Huntington Beach, and Tustin. There are no confirmed cases of human infections at this time in Orange County.

District staff will conduct additional mosquito trapping in the area around El Camino Real Park and distribute flyers alerting residents to the detection of the virus. Additional inspectors have been deployed to canvass the area to look for mosquito breeding sources and expand public education.

“The increased temperatures and humidity creates an ideal environment for mosquitoes to breed, it is critical that residents take the necessary steps to eliminate potential mosquito breeding sources and prevent mosquito bites.” said Lora Young, OCMVCD’s Director of Communications.

West Nile virus is transmitted to humans via the bite of infected mosquitoes, which become infected when feeding on birds carrying the virus. Most individuals infected with WNV will not experience any illness. Others will have flu-like symptoms, such as fever, headache and body aches. In severe cases, people will need to be hospitalized, and in rare cases the disease can be fatal. Young children, the elderly, or individuals with lowered immune systems are at greater risk to experience severe symptoms when infected.

Since its introduction in 2003, WNV has infected more than 6,500 people and has caused 292 fatalities statewide, according to the California Department of Public Health. West Nile virus is endemic in California and in Orange County, and presents a risk to public health every year.

Follow the tips below to prevent mosquito bites:

Apply mosquito repellent to exposed skin before going outdoors; reapply as recommended
Wear repellent containing DEET®, Picaridin, IR3535, or oil of lemon eucalyptus
Close all unscreened doors and windows to prevent mosquitoes from entering your home or space; repair broken or damaged screens
Wear long-sleeved shirts and long pants, and opt for lighter-colored clothing

Around the home, eliminating breeding sources for mosquitoes is critical:

Dump and drain containers filled with water at least once a week
