Researchers have identified a new strain of human immunodeficiency virus (HIV), the first discovered after 2000, informs the Press Association, cited by Agerpres.
It is the first time a new subtype of Group M has been identified, the most common strain of HIV virus, following the establishment of classification guidelines, at the turn of the century.
Group M viruses are responsible for the global pandemic, and its origin has been identified by researchers in the Democratic Republic of Congo (DRC), in sub-Saharan Africa.
Researchers have noted that the new discovery helps them to be one step ahead of a mutant virus and prevent new pandemics.
Before an unusual virus can be detected, a new subtype has to be independently detected three cases.
The first two samples of the new HIV-1
The third, collected in 2001, was difficult to sequence at that time due to the amount of viruses in the sample and existing technology.

Carole McArthur of the University of Missouri-Kansas City, one of the study's authors, said: & # 39; In an increasingly connected world, we can no longer believe that viruses can be restricted within an area. This discovery reminds us that in order to end the HIV pandemic, we must continue to take on the ever-changing virus and use the latest technological advances and resources to monitor its development. & # 39; & # 39;
Existing diagnostic tests and medications Antiretroviral drugs that suppress HIV development are designed to target areas of the virus common to all groups, the Press Association notes.
The HIV virus causes AIDS, which gradually attacks and destroys the body's immune system. The disease manifests itself through serious infections that cause weight loss, the brain and central nervous system.
To reproduce, HIV must enter a cell in the immune system. The virus enters the body through sexual contact, through contamination with the infected blood or from the infected mother to the fetus, during pregnancy, birth and breastfeeding. HIV can be found in biological fluids, such as blood, sperm, vaginal secretions and breast milk.
An HIV positive person does not necessarily have signs of the disease. However, it is a virus carrier and therefore susceptible to transmission.
