For example Anopheles mosquito. #T- Lymphocyte cells (Immune cells) have another name called T-helper cells that defend our body from infection. #Opportunistic diseases: diseases caused by different disease-causing organisms that occur when the body has a disease resistance mechanism. #Retroviral drugs are used to stop or reduce viral replication in humans, but they don’t kill the virus. #Endemic: This disease occurs when a disease-causing agent exists permanently in a specific place or population, For example, malaria is endemic in the Afar region. #Epidemics are diseases that occur suddenly and then spread in a specific area or within a specific population group, For example, in 2015 Ebola was an epidemic in West Africa. #pandemic is an epidemic that spreads far more widely worldwide. It affects a huge number of people. Example COVID-19
