Los Angeles County is on alert after the detection of H5 avian flu at a local wastewater sampling site. The Department of Public Health is now diving into the task of identifying potential sources of the virus, which has caused a nationwide outbreak among birds and mammals, though it remains at low levels within the County.
As of now, reports of human cases of the H5N1 strain in Los Angeles County are nonexistent, and the risk to residents continues to be low, despite the virus's presence in both northern and southern California, including more than 200 dairies. Public Health officials and agencies, including the CDC and state agriculture counterparts, are tracking developments closely, according to a bulletin released by the County. The virus may have entered wastewater systems through various avenues, such as infected wild bird droppings or the disposal of contaminated animal products.
Key risk groups are under scrutiny, particularly dairy and meat processing sites, where the virus could have originated. Public Health is working to ensure the identification and testing of symptomatic birds, pets, and wild mammals, a proactive measure to control the possible spread of H5N1. The department also engages in routine wastewater sampling aimed at surveillance for infectious diseases including this one, an effort that has proven its worth in detecting diseases before they can cause significant harm to the human population.
Preventative measures have been suggested to the public, and are critical in maintaining the low-risk status. Officials urge avoidance of raw dairy products and undercooked meats, and caution against direct contact with sick or dead animals, or areas contaminated with avian feces. Measures include observing birds from a distance, practicing hand hygiene when contact is necessary, and reporting any sightings of sick or deceased birds to local authorities. For pet owners, keeping animals away from such risks is advised. Notably, an annual flu vaccine is recommended, particularly for those who have or might be exposed to infected birds, despite it not being preventive for avian flu, it can reduce the risk of simultaneous infection with human and bird flu viruses.
Symptoms of H5N1 infection in humans are typical of influenza and can range from coughs and sore throats to gastrointestinal distress. However, not all infected individuals may exhibit fever, a factor to consider particularly in the elderly or those with immunosuppression. LA County residents with concerns or symptoms can contact the Public Health InfoLine daily for clinic locations or to speak with a doctor.
