The first two cases of people infected with the West Nile virus in Los Angeles County for the 2020 season were identified this month, public health officials said on Thursday.
While LA County confirmed its first positive mosquito test in early June, two residents of the San Fernando Valley area were reported to now have the virus, according to the county’s Department of Public Health. One case was in an “older” without major disease who was hospitalized with a neuroinvasive disease in early July and recovering, and the second case was found in late July in a healthy blood donor whose positive blood units were discarded, they said. employees,
The number of cases excludes Long Beach and Pasadena, as cases identified in these cities are reported by their local health services.
“The West Nile virus continues to be a serious threat to the health of Los Angeles County residents. We encourage residents to cover, clean or get rid of objects that can hold water and breed mosquitoes both inside and outside your home. This is more important now than ever because we spend most of our time at home, ”said LA County Health Officer Muntu Davis.
“We are currently in the peak season of mosquitoes in Los Angeles County, and residents must also protect themselves from mosquito-borne diseases by using EPA-registered mosquito repellents,” Davis said.
Mosquitoes infected with the West Nile virus were found in three cities in Orange County earlier this month. This year’s mosquito count is nearly five times higher than last year’s and doubles the five-year average from the OK, officials said in June.
People get the virus from being bitten by an infected mosquito, according to the agency. But most mosquitoes do not carry the virus.
Those infected with West Nile virus may experience mild symptoms, including fever, muscle aches and fatigue. In some cases, especially in people over the age of 50 and those with chronic conditions such as cancer and diabetes, a severe infection can occur and affect the brain and spinal cord.
There is no specific treatment for the disease and no vaccine to prevent infection, according to the public health department.
More than three-quarters of reported cases in LA were severe and approximately 7% of patients died from complications, the department said.
The county public health office recommends that the following measures be taken to reduce the risk of exposure to bloodthirsty insects:
- PROTECT ONLY: Mosquito repellents can prevent mosquitoes from biting you. EPA-registered repellents containing DEET, picaridine, IR3535, 2-undecanon and lemon eucalyptus oil are the longest lasting and most effective. Available as sprays, wipes and lotions. Find the right repellent for you here. Consider wearing long-sleeved clothes and pants when you’re out and about.
- MOSCOW PROVES YOUR HOME: Make sure your doors and windows have tight-fitting screens to protect against mosquitoes. Repair or replace screens with tears or holes.
- REDUCING MOSCOW: Mosquitoes lay their eggs in standing water. Check for items that retain water inside and outside your home once a week. Cover water storage containers such as buckets and barrels. If there is no cover, use wire mesh with holes smaller than an adult mosquito. Clear standing water in flower pots, plates, bird baths and other containers. Clean and maintain pools, spa and water drains from pool covers.
