San Diego County health officials have reported the first locally acquired case of West Nile Virus this year in a 53-year-old La Jolla man.


The patient was hospitalized but is expected to recover.

West Nile virus is mainly a bird disease but can be transmitted to people by certain species of native San Diego County mosquitoes that first feed on an infected bird or animal and then a bite a person.

At least 80% of people who become infected with West Nile virus never know it and never suffer any symptoms. About one in five people who are infected develop a fever and other symptoms such as headache, nausea, fatigue, skin rash or swollen glands. About 1 out of 150 infected people will develop serious illness.

There was one West Nile virus case in San Diego County in 2020, three in 2019 and two in 2018.
