The H1N1 virus does not typically lay dormant in the human body like some other viruses, such as herpes viruses. Instead, it usually causes an acute respiratory infection that the body clears relatively quickly. After infection, the immune system generally eliminates the virus, and any remaining antibodies provide protection against future infections. However, like other influenza viruses, H1N1 can mutate, leading to new strains that may evade immune protection.
