The CDC is expanding its testing of international air travelers for flu, RSV, COVID-19, and other viruses. Seven U.S. airports are participating in some fashion, either collecting voluntary nasal swabs or aircraft wastewater or both.
The study reveals that the SARS-CoV-2 delta variant was transmitted from humans to lions at a Singapore zoo, emphasizing the risk to captive and endangered animals. The researchers call for strict infection control measures and suggest vaccinations for susceptible animals to protect them from anthropogenic viral transmissions.
Early detection of emerging SARS-CoV-2 variants is critical to assessing risk, providing clear and timely communication messages, and coordinating public health action. CDC used a multicomponent surveillance approach to track the global spread of the SARS-CoV-2 variant BA.2.86.
