Preexposure is referred to as the delivery of antiretroviral medications to an uninfected person before and during potential HIV exposure to lower the risk of infection. The logic behind this method is to give a preventative dose of the drug(s) before being exposed to HIV so that HIV replication is suppressed as soon as the virus enters the body and HIV cannot develop a permanent infection.

You should know about HIV preexposure prophylaxis to be safe.Continuing high-risk sexual behavior, such as violent sex, coercive and non-consensual sex, rape, and unprotected sexual activities, makes women the most vulnerable to sexually transmitted infection/HIV, necessitating a more radical approach to HIV prevention in high-risk individuals do not have HIV.

Difference between HIV PrEP and PEP

Patients with HIV can prevent transmission by sharing HIV PrEP and PEP information with their sex and drug injection partners who do not have HIV. Health care practitioners can also volunteer to support the dialogues or refer partners to providers who can give PrEP and PEP.

• PrEP is used by HIV-negative people at high risk of contracting with the virus through sexual contact or through injectable drug use. These drugs can help prevent HIV infection in those exposed to the virus through sex or injectable drug use. Find out more about PrEP.

• PEP is used as antiretroviral medications to prevent HIV infection in HIV-negative people after a single high-risk exposure. To be successful, PEP must be started as soon as feasible – always within 72 hours of potential vulnerability – and sustained for four weeks. Find out more about PEP.

PEP's is very effective in Reducing Your Risk of Contracting HIV infections. PrEP is likely to be a superior preventative method than PEP for those who inject drugs and have many exposures.

What can reduce the chances of contracting HIV?

• Get an HIV test done.

Before you have sex, reduce your risk of HIV infection, talk to your partner about HIV testing, and get tested. Find an HIV testing center near you using the Centers for Disease Control and Prevention's (CDC) testing locator.

• Select sexual acts that are less dangerous.

Having anal or vaginal sex without using a condom or taking HIV prevention or treatment medications is a way for HIV to spread.

Anyone can contract HIV, but there are things you can do to protect yourself.

• When you have sex, always use condoms. Read this CDC fact sheet to learn how to properly use condoms.

• Don't use needles to inject drugs. If you must, use only sterilised medication injection equipment and water, and never share your equipment.

• You should get tested for STDs and treated if necessary. Insist on having your partners checked and treated as well. If you have an STD, you are more likely to contract HIV or spread it to others.

• Preexposure prophylaxis is something you should discuss with your doctor (PrEP). You should use this medicine wisely and in limited amount.
