Symptoms and spread of HIV and AIDS

IIn the first stages of HIV infection, most people will have very few, if any, symptoms. Within a month or two after infection, they may experience a flu-like illness,

EARLY SYMPTOMS:-

  • Fever
  • Headache
  • Tiredness
  • Enlarged lymph nodes in the neck and groin area
  • These symptoms usually disappear within a week to a month and are often mistaken for another viral infection, such as flu.

Following initial infection, you may have no symptoms. The progression of disease varies widely among individuals. This state may last from a few months to more than 10 years.During this period, the virus continues to multiply actively and infects and kills the cells of the immune system. The immune system allows us to fight against the bacteria, viruses, and other infectious causes.The virus destroys the cells that are the primary infection fighters, called CD4+ or T4 cells.

LATER SYMPTOMS:-

                   During the late stages of HIV infection, the virus severely weakens the immune system, and people infected with the virus may have the following symptoms:

  • Rapid weight loss
  • Recurring fever or profuse night sweats
  • Extreme and unexplained tiredness
  • Prolonged swelling of the lymph glands in the armpits, groin, or neck
  • Diarrhea that lasts for more than a week
  • Sores of the mouth, anus, or genitals
  • Pneumonia
  • Red, brown, pink, or purplish blotches on or under the skin or inside the mouth, nose, or eyelids
