New strain of hiv virus

The fight against HIV has made some formidable gains in treatment and treatment outcomes with remarkable gains in longevity. Undoubtedly one of the most promising achievements is the reduction in mother-to-child transmissions around the world.

But the HIV response does not favour complacency. The notion that HIV is no longer an emergent threat is one that jeopardises the work of scientists and communities who continue to drive prevention of HIV and fight against the pervading stigma. The HIV emergency is not over. The epidemic still needs vigilant attention, especially as reduction rates stall.

The ultimate solution is a working cure and preventative vaccine. But they were halted in early February This points to the need to refocus our energy on scaling up the effective treatment and prevention tools we have in hand to all those who need them.

There are now many types of antiretroviral drugs available to treat HIV.

According to the National Institutes of Health NIH , taking antiretroviral medications each day as directed can reduce viral load to undetectable levels in 6 months or less. Not only can having an undetectable viral load keep the immune system healthy, but it can also prevent transmission of HIV to others.

People with an undetectable viral load have no risk of transmitting HIV to their partners via sex. HIV-2 is rare outside of western Africa. HIV-1 viruses are very diverse. There are four groups of HIV Viruses in Group M are further divided into nine subtypes, which can be made up of numerous variants, or strains. Getting tested for HIV is important after a potential exposure. Antiretroviral medications can be used to effectively reduce virus to undetectable levels. Reads this article in Spanish.

Can you contract more than one strain? Comparisons chart. Does it have groups? The sample was small, and while it seemed similar to the two older samples, scientists wanted to test the whole genome to be sure.

At the time, there wasn't technology to determine if this was the new subtype. So scientists at Abbott and the University of Missouri developed new techniques to study and map the sample. Rodgers said it was "like searching for a needle in a haystack," and then "pulling the needle out with a magnet. They were able to fully sequence the sample, meaning they were able to create a full picture of what it was, and determine that it was, in fact, subtype L of Group M.

It's unclear how this variant of the virus may impact the body differently, if it does act differently at all. Current HIV treatments can fight a wide variety of virus strains, and it is believed that these treatments can fight this newly named one. Get CNN Health's weekly newsletter.
