Adenovirus is a type of DNA virus that can infect various hosts, including humans. It is responsible for a wide range of illnesses, from mild respiratory infections to more serious conditions such as pneumonia and gastroenteritis. Adenoviruses are known for their ability to cause outbreaks in settings such as hospitals, schools, and military installations. Research in this area focuses on understanding the different strains of adenovirus, their modes of transmission, and how they interact with the host immune system. Scientists are also working on developing vaccines and antiviral treatments to prevent and treat adenovirus infections. Additionally, research is conducted to investigate the potential use of adenoviruses as vectors for gene therapy and cancer treatment.
