(CNN) – A new subtype of the Human Immunodeficiency Virus (HIV) has been identified.
More than 37 million people have been infected worldwide with HIV or AIDS.
HIV is the virus that causes AIDS.
The new strain of HIV is more like an ancestral strain, and it’s likely circulating in the Democratic Republic of Congo.
Researchers hope identifying new viruses like this one will help ensure new pandemics are stopped.
This is the first time a new strain has been identified since 2000.
