CMV, or Cytomegalovirus, is a common virus that belongs to the herpesvirus family. It can infect people of all ages and is usually harmless in healthy individuals. However, CMV can cause serious complications in people with weakened immune systems, such as those with HIV/AIDS, transplant recipients, and newborn babies. Research on CMV focuses on understanding how the virus causes disease, developing diagnostic tests, and exploring potential treatments and vaccines. Scientists are also studying how CMV interacts with the immune system and its potential impact on chronic diseases such as cancer, cardiovascular disease, and autoimmune disorders. Overall, research on CMV is aimed at improving our understanding of the virus and developing strategies to prevent and treat CMV-related diseases.
