Ways of HIV infection

Blood sugar

Direct blood transfusion from people with HIV to normal people is the fastest way to spread HIV. However, this case is very rare because before taking blood, it is necessary to go through the test to see if it is eligible for transmission.

HIV virus is in the blood of patients, when injecting needles, containing HIV-infected blood. After this needle is not cleaned, it will be injected to another person, leading to the transmission of the virus.

Sex

HIV infection rate for each unprotected relationship is estimated at 0.1% to 1%. This rate will increase with the frequency of relations. Sex with condoms is still at risk of HIV infection, but the rate is much lower. Condoms increase safety by up to 90-95% if practiced properly.
