Syphilis - history, incubation period
The development of AIDS is the last stage of HIV infection. The immune system is destroyed, and the patient is left defenseless against various infections, under normal conditions trivial, and now potentially deadly. About a third of patients experience symptoms of a brain infection. Usually rare blood vessel tumors, manifested as nodules on the skin, are a common, sometimes the first symptom of AIDS, called Kaposi's sarcoma. Some symptoms and infections can be cured, but the total destruction of the immune system cannot be restored. AIDS is a deadly disease.
Pregnancy in a woman with HIV can be a double tragedy: the child can be born infected, and the mother has an increased risk of developing AIDS. Many babies born to infected mothers are infected from birth; in addition, the virus can be transmitted with breast milk. Children reach the later stages faster, because their immune systems are still immature.
Syphilis, since its sudden, unexplained appearance in the 15th century, until the discovery of antibiotics in the second half of the 20th century, who were able to fight it, was the most serious sexual disease. Over the past few decades, the incidence of syphilis has decreased markedly, but studies conducted in 1988 showed a steady increase in the incidence among prostitutes, drug addicts, their sexual partners and newborn babies, and studies in the 1990s revealed a high incidence of syphilis among HIV-infected. A particularly high-risk group consists of homosexual men.
Syphilis - Etiology
Syphilis is caused by tiny, spin-shaped bacteria called spirochetes. They bloom magnificently in the warm, moist membranes of the genital passages, rectum and mouth, but they die almost instantly outside the human body. Therefore, the infection is transmitted almost exclusively through sexual contact. Whether the penis, the tongue or (possibly) the finger are caressing the organ, and the mouth, the genitals or the anus are the recipient, the syphilitic focus on one can infect the second.In very rare cases, syphilis is transmitted through close, non-sexual contact (and this sometimes happens with doctors or dentists during work), but it cannot be transmitted by physical objects, such as a toilet seat, towel or cup. However, it can be inherited from an infected mother, which sometimes leads to stillbirth or congenital deformity, and in other cases a latent infection may appear later.
Syphilis - Incubation Period
There is an “incubation period” between infection with syphilis and the appearance of its first signs, which can last from 9 days to 3 months, but usually not less than 3 weeks. On infection, about 1000 pathogens are transmitted on average. After 3 weeks, their number increases to 100-200 million. If they are not fought, they can eventually capture the entire body, leading to death. Syphilis has four stages. In each stage, their symptoms, although the latter can vary and generally absent.
