About one third of all the pneumonias in the US each year are caused by respiratory viruses. The most common viral cause of pneumonia for adults is the flu virus (influenza). The most common viral cause of pneumonia in children younger than one year of age is respiratory syncytial virus (RSV). In HIV+ children, cytomegalovirus-associated pneumonias are also common.
TB often occurs as a lung infection, but can affect almost any organ of the body. Mycobacterium tuberculosis, the bacterium that causes TB, can spread when a person with active TB disease coughs, sneezes or spits. Tiny droplets of fluid from the lungs are carried in the air and can be inhaled by someone nearby.
In healthy people, the immune system can usually prevent the bacteria from causing symptoms of TB (active disease). In HIV+ people, the bacteria may get out of control, resulting in active disease with symptoms. TB and HIV make each other worse. Worldwide, TB is the leading cause of death in HIV+ people. For more information on TB, please see our Tuberculosis info sheet.
Pneumonias can be very serious for HIV+ people. However, ongoing medical care allows for the effective prevention or early diagnosis and treatment of pneumonias.
