Pneumonia is an inflammation of the lungs, typically caused by an infection. This infection can be bacterial or viral, and less commonly, fungal. It can also occur if foreign material, like food or water, enters the lungs. While many individuals recover within 2 to 4 weeks, certain groups are more vulnerable to severe illness. These include infants, older people, and those with pre-existing heart or lung conditions. Treatment usually involves antibiotics, and in more serious cases, hospitalization may be necessary for fluids, oxygen, and sometimes steroids. Rest, fluids, and pain relievers aid recovery.
