Mistake 11: Blood from blood donation centers is absolutely safe, no need to worry about contracting STDs AIDS has an empty window and there is no effective method to test for it (therefore, although blood from blood donation centers is screened for syphilis and AIDS, there is no guarantee that it is absolutely safe.) Mistake 12: As long as you don’t get involved in inappropriate places, you won’t get STDs. Vesicles and warts can often be contracted without sexual intercourse, and blood transfusions and sharing needles and syringes with STD carriers can lead to infection with STD syphilis and AIDS. The majority of STDs have an effect on the offspring. Syphilis or non-gonococcal urethritis pathogens can be transmitted to the fetus through the placenta, leading to miscarriage, premature birth, embryonic death, congenital malformations, fetal syphilis; Chlamydia trachomatis can lead to intrauterine growth retardation; spontaneous abortion is mainly associated with gonorrhea, mycoplasma or herpes simplex virus; gonorrhea can cause gonorrhea in newborns, resulting in defective Newborn babies are born, and can also lead to neonatal ophthalmia resulting in blindness. Mistake 14: If you get an STD, your partner doesn’t need to be treated if you don’t have symptoms. If you get an STD, your partner must be tested and treated at the same time to avoid ping-pong infection. Mistake 15: STDs only show symptoms in sexual organs Besides genitalia, symptoms of STDs may also appear in other organs of the body, including the skin, mouth, eyes, rectum, near the anus and joints of the whole body.
