Many people do not feel symptoms of HIV in the first few months after infection and may not know that they are infected. Others may experience influenza-like symptoms, including fever, headache, rash and sore throat. However, these first few months are when the virus is most infectious.
As the disease progresses, symptoms will be expanded and more pronounced. These can include swollen lymph nodes, weight loss, fever, diarrhoea and cough. HIV weakens the body’s ability to fight other infections, and without treatment people will become more susceptible to other severe illnesses such as tuberculosis, cryptococcal meningitis, bacterial infections and some cancers including lymphomas and Kaposi’s sarcoma.
Diagnosis of HIV uses rapid tests that provide same-day results and can be done at home, although a laboratory test is required to confirm the infection. This early identification greatly improves treatment options and reduces the risk of transmission to other people including sexual or drug-sharing partners
HIV/AIDS
Human immunodeficiency virus (HIV) is an infection that attacks the body’s immune system, specifically the white blood cells called CD4 cells. HIV destroys these CD4 cells, weakening a person’s immunity against infections such as tuberculosis and some cancers.
WHO recommends that every person who may be at risk of HIV should access testing. People diagnosed with HIV should be offered and linked to antiretroviral treatment as soon as possible following diagnosis. If taken consistently, this treatment also prevents HIV transmission to others.
If the person’s CD4 cell count falls below 200, their immunity is severely compromised, leaving them more susceptible to infections. Someone with a CD4 count below 200 is described as having AIDS (acquired immunodeficiency syndrome).
HIV can be diagnosed using simple and affordable rapid diagnostic tests, as well as self-tests. It is important that HIV testing services follow the 5Cs: consent, confidentiality, counselling, correct results and connection with treatment and other services
