Influenza A is a type of virus that causes the flu in humans and animals. It is known for its ability to mutate rapidly, leading to seasonal outbreaks and occasional pandemics. Research in this area focuses on understanding the virus's genetic changes, developing effective vaccines and treatments, and predicting and preventing future outbreaks. Scientists study the virus's structure, transmission, and immune response to inform public health strategies and improve control measures. Additionally, research on influenza A helps to monitor the virus's evolution and identify new strains that may pose a threat to global health.
