On November 9, the Long Beach Department of Health and Human Services in California announced the confirmation of the first case of St. Louis Encephalitis (SLEV) in the city since 1984. This viral disease is primarily transmitted to humans through the bites of infected culex mosquitoes.

According to the Center for Disease Control (CDC), most individuals infected with SLEV do not show any symptoms. However, those who do develop symptoms may experience fever, headache, nausea, vomiting, and fatigue. It is crucial for residents to be aware of these symptoms and seek medical attention if necessary.

The infected individual was promptly hospitalized but is now in the process of recovering at home, as stated in a press release from the health officials of the Long Beach Department of Health and Human Services. Currently, there have been no additional reported cases of SLEV.

Mayor Rex Richardson expressed the department's commitment to preventing further cases by collaborating with healthcare providers in educating the community. "Mosquito control is a shared responsibility," Mayor Richardson emphasized, urging residents to actively participate in reducing the risk of mosquito-borne illnesses in their neighborhoods.

Within the state of California, twelve other cases of SLEV have been confirmed since November 2023. Health officials have warned that the mosquitoes responsible for transmitting the virus are most active at dawn and dusk—a crucial piece of information to be mindful of when outdoors.

The Long Beach health department continues its surveillance efforts, working alongside local authorities to monitor the situation closely. To date, no mosquito samples have tested positive for SLEV, but precautions remain necessary.

Health Officer Anissa Davis, in an interview with the East Bay Times, emphasized the importance of protecting oneself against mosquitoes. Davis stated, "The first confirmation of SLEV in Long Beach should serve as a reminder that we need to protect ourselves against mosquitoes." The Health Department encourages residents to report any mosquito control issues in their respective areas.

As the city grapples with this concerning development, it is crucial for Long Beach residents to stay informed about mosquito control measures and take necessary precautions to prevent further spread of the St. Louis Encephalitis virus. The health and well-being of the community are of utmost importance, and everyone must play an active role in keeping themselves and their neighborhoods safe from mosquito-borne illnesses.
