Common types of viral diseases include cold, influenza, chickenpox, HIV/AIDS, viral hepatitis, HPV, viral meningitis, herpes, etc. These diseases are often contagious. When a virus enters the body and starts to multiply, they can spread from one person to another. Some of these viral diseases can be life-threatening, causing complications like pneumonia and diarrhea.
Viruses can spread from one person to another in different ways. For instance, air, food, or water contaminated with virus, or having sexual contact with an infected person can cause viral disease. In some cases, virus hosts, like mosquitoes or mouse can transmit the disease.
People of all ages can be affected by a viral disease. However, the very young and very old, and also those with chronic diseases or a compromised or suppressed immune system are at greater risk of complications from these diseases. Centers for Disease Control and Prevention reports that between 71% and 85% of seasonal flu-related deaths occur in people 65 years and older each year, mainly because with age, human immune defenses become weaker. In the U.S., 57,062 persons died in 2015 due to influenza and pneumonia.
