HIV begins to become resistant to drugs

HIV tends to develop complications when it begins to resist Tenofovir, the drug used to prevent and fight this virus.

In some African countries, the rate of HIV resistance to Tenofovir is up to 60%. This result is "extremely worrying", BBC quoted Dr. Ravi Gupta from University of London (UK) as saying.

Over four years, Dr. Gupta and his colleagues compared HIV patients from different continents and found that the rate of resistance to Tenofovir in Africa was 60%, while the figure in Europe was 20%. Writing in The Lancet, the authors said it was likely due to incorrect use of the drug. "If the dose is not taken correctly, for example, too little or not regularly, the virus will overcome and become resistant to the drug," Dr. Gupta said.

More dangerously, Tenofovir-resistant HIV strains can be transmitted from person to person. Experts are continuing to research to better understand how drug-resistant viruses develop and spread.

According to the World Health Organization, HIV remains the world's most deadly infectious disease. In 2014, there were 36.9 million people living with HIV worldwide.
