Adults can get influenza A. Influenza A itself is a contagious disease that is susceptible to the entire population, and adults with low immunity can also be infected and need to take good personal protective measures. Influenza A is influenza A, a common infectious virus of the respiratory system that usually occurs in spring and fall. Influenza A can occur in people of all ages, including adults. Elderly people and children are slightly more likely to get influenza A than adults because their immune systems are not well developed. In high-risk areas where influenza A is densely distributed, there is no significant difference in the likelihood of infection among all groups of people. During the high season of Influenza A or the change of seasons between spring and fall, it is recommended that adults or other susceptible people should take personal protection measures, and can wear masks to effectively isolate droplet transmission, which can greatly reduce the chance of Influenza A infection. At the same time, when there are infected people around, you should maintain an effective distance of personal protection and do a good job of hand cleaning. Because influenza A is highly contagious, it is recommended that all people need to take protective measures.
