To describe: The HIV virus and its effect on the immune system.
Introduction: Viruses can spread through various agents such as air, water, direct contact, and many more. HIV (Human immunodeficiency virus) is a virus, which spreads through direct contact. HIV causes acquired immuno deficiency syndrome (AIDS), which makes a person immunocompromised thus exposing it to multiple infections.
To explain: The pathological changes which can be observed due to HIV infection.
Introduction: Viruses can spread through various agents such as air, water, direct contact and many more. HIV is a virus which spreads through direct contact. Human immunodeficiency virus causes acquired immuno deficiency syndrome which makes a person immunocompromised thus exposing it to multiple infections. Acquired Immuno Deficiency Syndrome abbreviated as AIDS is caused by HIV virus. This virus affects T cells responsible for acquired immunity. This disease makes a person immuno compromised and can prove to be fatal. Modern medicines can help in controlling this disease and provide a better life expectancy.
