Prophylaxis (PEP Post-Exposure)
PEP is any prophylactic (preventive) treatment started immediately after exposure to blood or bodily fluid contaminated with a pathogen (such as a disease-causing virus), in order to prevent infection and the development of disease.
Although multiple diseases can be transmitted from exposure to blood, the most
serious infections are hepatitis B virus (HBV), hepatitis C virus (HCV), and
HIV. Fortunately, the risk of acquiring any of these infections is low.
In order to be exposed to a blood borne pathogen, you must have contact with
blood, a visibly bloody fluid (i.e., phlegm or urine containing blood), or
another bodily fluid (i.e., semen or vaginal secretions) that contain an
infectious organism (virus or bacteria). The blood or fluid must come in direct
contact with some part of your body. A virus can enter your body through the
bloodstream, open skin, or mucous membranes, which include the eye, mouth, or
genitals. Contact with skin that is intact (without new cuts, scrapes, or
rashes) poses no risk of infection.
Thus, exposure to a blood borne pathogen is possible after:
A skin injury such as a needle stick or cut with a sharp object and/or contact
with a mucous membrane (including exposure through sexual intercourse,
especially if an ulcer is present or vaginal/rectal tissues are injured) or
non-intact skin.
What do I do after blood or body fluid
exposure?
• Wash the area - The first and most
important step after being exposed to blood or bodily fluids is to wash the
area well with soap and water. You can clean small wounds and punctures with an
antiseptic such as an alcohol-based hand gel, since alcohol kills HIV,
hepatitis B virus, and hepatitis C virus. However, the alcohol may sting. For mucosal
surfaces (mouth, nose), the area should be flushed with copious amounts of
water. Eyes should be flushed with saline or water. There is no evidence that
expressing fluid by squeezing the wound will further reduce the risk of blood
borne infection. we suggest you best If you are searching best HIV exposure treatment in Delhi for medical checkup.
What can the doctor do after implementing first aid measures?
• Human immunodeficiency virus (HIV) -
Treatments are available to reduce the risk of becoming infected with HIV after
exposure. Previous studies have suggested that the use of an anti-HIV
medication, reduced the already low risk of healthcare workers becoming
infected with HIV by about 81% (but perhaps a higher rate of prevention with
the new anti-HIV agents available). The risk of becoming infected with HIV as a
result of other types of exposure (i.e., trauma, rape) is probably even lower
than the risk of infection after a needle stick.
Anyone who is exposed to potentially infected
blood or bodily fluids should be tested for HIV at the time of exposure
(baseline) and at six weeks, three months, and six months post exposure. The
baseline HIV test is necessary (and required) to document that the HIV
infection was not already present at the time of the incident. Experts from the
United States Center for Disease Control recommend use of medications to reduce
the risk of HIV infection if all of the following criteria are met:
• Exposure occurred less than 72 hours previously
• One or more of the following areas were exposed: the vagina, rectum, eye,
mouth, or other mucous membrane, open skin, through the skin (i.e., from a
sharp object or needle)
• One or more of the following bodily fluids were involved in the exposure:
blood, semen, vaginal secretions, rectal secretions, breast milk, or any body
fluid that is visibly contaminated with blood.
However, the CDC also recommends that each situation be considered on an
individual basis; preventive treatment may be recommended to people who do not
meet these criteria in some situations. The CDC recommends NOT using preventive
treatment when: the exposure occurred more than 72 hours prior; when intact
skin was exposed; or when the bodily fluid is urine, nasal secretions, saliva,
sweat, or tears, and is not visibly contaminated with blood. Are you find std

The Centers for Disease Control and
Prevention (CDC) recommends a combination of two or three medications to
prevent developing HIV after exposure; the best regimen should be determined by
a healthcare provider who is experienced with HIV prevention and treatment
regimens. The optimal length of preventive treatment is unknown, although four
weeks is generally recommended.
• Hepatitis B - The risk of becoming infected with hepatitis B is greater than
the risk of becoming infected with other viruses. Fortunately, there is an
effective vaccine that can help to prevent infection.
• Hepatitis C - HCV can cause a form of hepatitis that leads to chronic liver
disease. There is no known way to prevent this infection following exposure.
Blood tests should be done immediately after exposure to measure your liver
function and test for the presence of hepatitis C; the tests should be repeated
after four to six weeks and again after four to six months or sooner if
symptoms of hepatitis develop. On an individual bases a physician may recommend
anti-HCV treatment in patients recently infected with hepatitis C.
