What is Blood fluids?

Blood and body fluids, such as saliva, semen and vaginal fluid, can contain viruses that can be passed on to other people. Other body fluids,

such as sweat, tears, vomit or urine may contain and pass on these viruses when blood is present in the fluid, but the risk is low.

Protect yourself

•    Use latex condoms correctly.
•    Do not inject drugs.
•    Limit alcohol consumption. People take more risks when intoxicated.
•    Do not share needles or any devices that can break the skin. That includes needles for tattoos, piercings, and acupuncture.
•    If you receive medical or dental care, make sure the equipment is disinfected or sanitized.

Spread through sexual contact

These infections are most commonly transmitted by sexual contact:

  • genital to genital
  • oral to genital
  • genital to anal.

Examples of sexually transmitted infections:

  • Chlamydia infection
  • genital herpes
  • genital warts
  • gonorrhoea
  • hepatitis B
  • human immunodeficiency virus (HIV) infection
  • non-specific urethritis (NSU)
  • pubic lice (crabs)
  • syphilis
  • trichomoniasis.

Infectious Diseases in Saliva

Infectious diseases can be spread through several routes of transmission. When a person accidentally consumes microbe-contaminated items, such as saliva during kissing, the swallowing action of the tongue wipes the microbes against the back of the throat, allowing the microbe to enter the body.

Infections, such as mononucleosis caused by Epstein-Barr virus (EBV), and cytomegalovirus (CMV), are examples of infections spread via oral transmission from virus-containing saliva.

Saliva does not contain HIV or hepatitis C but may contain small amounts of hepatitis B.
