Practice safer sex, do not share needles and avoid contact with blood. Safer sex basically means ..
A condom should be put on (properly) before there is any genital contact. Use a non-spermicidally-lubricated condom with extra water-based or silicone lubricant at all times. It is useful to wear an extra-strong condom, but more important to use sufficient lubrication, without which the condom is more likely to burst. Never move from anal to vaginal sex without changing the condom. If there is no spare condom handy, move from the vagina to the anus. === === Cover cuts, sores and other skin lesions on fingers with waterproof plasters or latex gloves, particularly during a menstrual period or if anal foreplay is involved. If you do not have latex gloves to hand, it is safer to use a non-spermicidally-lubricated condom over one or two fingers than bare hands. If you are not using protection and you are going to move on to vaginal foreplay, it is vital to wash your hands after anal foreplay. If you are sharing toys, use the same level of protection as for penetrative sex. Wash toys thoroughly between partners. Keep whips, chains and other articles used during S&M (sadomasochistic) fetish foreplay for personal use, particularly if you draw blood (or body fluids containing blood) during use. There is no risk of infection if you are alone and using unshared items, unless a disease from one part of the body infects another through poor hygiene technique. An unwashed finger, for example, can spread genital gonorrhea or chlamydia to the eye. During masturbation with a partner, follow the guidelines for foreplay. Use a non-spermicidally-lubricated condom, or a dental dam. Take care not to rip the condom and ensure that you have good oral health (do not brush your teeth or floss within an hour of engaging in oral sex and do not use a mouth wash).

Handwashing
Abstinence is indeed the most effective way to prevent contracting a sexually transmitted disease (STD) because it eliminates any risk of exposure to infected partners. By refraining from sexual activity, individuals can protect themselves from both STDs and unintended pregnancies. However, for those who are sexually active, consistent and correct use of condoms and regular testing can significantly reduce the risk of STDs. Education about safe sex practices is also crucial in preventing the spread of infections.
The most effective weapons against germs are proper hand hygiene (washing hands with soap and water) to prevent the spread of germs, cleaning and disinfecting frequently-touched surfaces, and practicing good respiratory hygiene (covering coughs and sneezes). Additionally, vaccines are an important tool to help prevent the spread of infectious diseases.
Viral conjunctivitis spreads through contact with infected eye secretions or contaminated surfaces. The most effective ways to prevent its transmission include washing hands frequently, avoiding touching the eyes, and not sharing personal items like towels or eye makeup.
The most effective spray for dogs' paws to prevent excessive licking is a bitter apple spray.
Aside from abstinence from vaginal sex, the contraceptive implant Nexplanon is the most effective. It has the lowest failure rate, there is no way that patient error can affect how well it works, and it's completely reversible.
The most effective measures to prevent Zika virus transmission include using insect repellent, wearing long sleeves and pants, using screens on windows and doors, and removing standing water where mosquitoes breed. Additionally, practicing safe sex and avoiding travel to areas with Zika outbreaks can help prevent the spread of the virus.

Prevention is the safest and most effective method of birth control. Hormonal methods (the Pill, Mirena IUD, Patch, implant, DepoProvera) are highly effective when used as directed. Barrier methods (cervical cap, diaphragm, condoms) are also effective. Some women choose abstinence and fertility awareness. Once a pregnancy is established abortion is the only means of termination.
