Researchers look for answers to HIV

Why is it that some Indians who are exposed to the Human Immunodeficiency Virus (HIV) don’t get Acquired Immunodeficiency Syndrome (AIDS)? How do the anti-HIV and anti-tuberculosis drugs interact with each other inside patients who have both the diseases? What is the pattern of drug resistance in the HIV-positive population?
 
These are just three of the many crucial questions that Indian researchers might be able to answer by tapping into a centralised repository of serum samples that the government is building. The samples would be collected from AIDS patients, and from people who are at a high risk of contracting it.
