Pathogen or Causal Organism:
American scientist identified and named the causal organism of AIDS as HCLV-III (Human cell leukemia virus-III), but now the name of the virus changed to HIV (Human Immuno Deficiency Virus).
Mode of Transmission: AIDS is not contagious disease. It does not spread through contact, caring of infected persons, sharing meals, kissing, mosquito bites, handshake, bite of insect, etc.
But AIDS can transmitted in following ways :
- Sexual Intercourse : Unprotected sexual intercourse with an infected partner, (if there is tissue injury to permit blood contact).
- Sharing Needles : Use of contaminated needles and syringes to inject drugs or vaccines.
- Sharing Utensils : Use of contaminated razors for shaving.
- Transfusion of Blood and blood Products : Transfusion of HIV contaminated blood can infect the recipient.
- Mother to Child : A woman infected with HIV may spread the disease through breastfeeding.
- Use of contaminated needles for boring pinnae.
- Organ Transplant: The organs of infected person spread HIV to recipient through organ transplant.
- Perturition from mother to baby due to rupturing of blood vessels.
