West Nile Virus Prevention Tips: How to Stay Healthy and Safe in Riverside County - Health

A child in Riverside County , California , has tested positive for the West Nile virus , marking the first human case of the virus in Southern California this year . The child , who has not been identified in terms of age or location , is expected to recover fully after being hospitalized . This case comes after two other human cases were reported in California earlier in the year , one in Fresno County and the other in Yuba County.

 West Nile virus is transmitted to humans and animals through mosquito bites . The mosquitoes become infected after feeding on birds carrying the virus . Horses are also at risk of contracting the virus . Infections typically occur in the summer and early fall months when temperatures are high , the air is humid , and mosquitoes are active . Riverside County has been experiencing particularly hot weather and high humidity due to monsoonal moisture.

While the overall risk of severe illness from the West Nile virus is low , it can be fatal , especially for high - risk groups such as individuals over 60 years old , those with weakened immune systems , diabetes , kidney disease , or other chronic medical conditions . Riverside County 's Public Health Officer , Dr. Geoffrey Leung , stressed the importance of taking precautions to prevent illness in these vulnerable groups.

Most people infected with the West Nile virus do not show any symptoms . However , about one in five infected individuals develop a fever along with symptoms like headache and nausea . Although most people recover completely , some may experience fatigue and illness for several weeks . Severe cases of the virus can lead to vision loss , paralysis , and even death , according to the Riverside County Health Department . To prevent mosquito - borne illnesses , Dr. Leung recommended the following precautions:

 Avoid being outdoors at dawn and dusk when mosquitoes are most active , wear long sleeves and pants when outside , use insect repellent containing DEET , and remove standing water around your home to eliminate mosquito breeding grounds.

In conclusion , the discovery of the first human case of the West Nile virus in Southern California serves as a reminder of the importance of taking preventive measures to reduce the risk of mosquito - borne illnesses . By following simple precautions , individuals can protect themselves and their families from potential exposure to the virus . It is crucial to remain vigilant , especially for high - risk groups , as the summer months continue and mosquito activity remains high in Riverside County.
