The Human Immunodeficiency Virus (HIV) has two different types of the infection, which are HIV-1 and HIV-2. While diagnosis, infection routes, and treatment are similar, they do both present with some differences that make approaches to managing the infection unique. The folks at HealthLine have a great article that identifies the key differences with each type of the infection.
While HIV-1 is more common worldwide, HIV-2 tends to transmit less efficiently and may have a better overall outlook. Both require treatment and follow-up.
