Vaccination plays a crucial role in preventing and controlling swine flu. Since the 2009 pandemic, the H1N1 strain has been included in seasonal influenza vaccines, providing ongoing protection against this specific virus. Annual influenza vaccination campaigns aim to reduce the impact of seasonal influenza, including H1N1, on public health. Surveillance is key to monitoring the circulation of H1N1 and detecting any potential changes in the virus. Surveillance systems track influenza-like illness, hospitalizations, and laboratory-confirmed cases to provide early warnings of emerging strains or unusual patterns. This data informs public health decisions, including vaccine composition for the upcoming influenza season. Ongoing research on swine flu involves studying the genetic evolution of the virus, understanding the factors influencing its transmission dynamics, and exploring novel antiviral treatments. Additionally, research efforts focus on improving the accuracy and speed of influenza diagnostics to enhance early detection and intervention.
