Everyone is still sensitive to this disease, which is a highly contagious STD, a sexually transmitted disease caused by syphilis spirochetes. Although the initial stage mainly occurs in the external genitalia localization, but if left unchecked, the whole body are very harmful, leading to neurological, cardiovascular and other systemic lesions, serious life are at risk. And syphilis spirochetes can be transmitted to the fetus through the placenta, the consequences are very serious is.

There is a situation in real life where a syphilis carrier may not have symptoms for many years. Early symptoms are not too obvious, and many people may not even know they have the disease. Even if an ulcer appears, perhaps it is ignored and left untreated for a long time. After the initial infection, small ulcers may flare up over a period of 1 to 20 years, and many patients then inadvertently infect others.

So, it is still very important to know the characteristics of syphilis, which allows us to treat it early to prevent it from becoming serious.

There is an incubation period for this disease, which is the period between the invasion of the pathogen into the organism and the initial appearance of the characteristics, and the incubation period varies from a few hours to a few months, or even a few years.

And syphilis is generally divided into three stages, stage I, stage II and stage III.

Stage 1 syphilis: The skin and mucous membranes are broken, and the syphilis spirochetes invade the body, first reproducing under the skin and mucous membranes, and then going through an incubation period of 2-4 weeks, and then forming a hard nodule or ulcer in the local area. There are also syphilis spirochetes that can enter the nearby inguinal lymph nodes along the lymphatic vessels, causing painless lymphadenitis, resulting in swollen lymph nodes, and stage 1 syphilis, also known as the hard chancre.

Clinical symptoms: the beginning of a hard knot, about the size of a fingernail, painless, itchy, soon ulcerated, but usually not pus, and will be accompanied by inguinal lymph node enlargement, but do not feel the pain. Usually, it occurs in the genital area, and in males it occurs in the coronary groove, near the foreskin, the body of the penis, the glans, the anus and the rectum. In women, it occurs in the labia majora and minora, perineum and cervix.

Stage 2 syphilis: In untreated stage 1 syphilis, the syphilis spirochete enters the bloodstream after 7-10 weeks, creating syphilis spirochete sepsis and spreading throughout the body. The site of infection at this stage is much more, and most tissues and organs may be infected, such as the skin, mucous membranes, lymph nodes, eyes, brain, liver, spleen and so on. An immune response is then triggered, and if the syphilis spirochetes are killed in the body, the disease will not continue to progress. Some data show that without treatment, 60%-70% of patients will not develop stage III syphilis and will terminate in stage II syphilis.

Clinical Symptoms: Some patients will have mild systemic symptoms in the early stage, such as low-grade fever, headache, fatigue, etc., and this usually lasts for 3-5 days. The main manifestations are syphilitic rash, flat warts, syphilitic alopecia, etc. The whole body can be infected, and it is accompanied by swollen lymph nodes.

Stage 3 Syphilis: After about 2 years, 30-40% of patients may develop stage 3 syphilis, also called advanced syphilis. Although stage I and II syphilis are highly contagious, there is less tissue destruction and it is easier to cure. If it reaches an advanced stage, the efficacy of the treatment is worse, and destructive, but also cause a variety of serious lesions.

Clinical symptoms: there will be nodular syphilis rash, gumbo, neurological syphilis, paralytic dementia, syphilitic aortitis and so on.

There is another situation that needs special attention, that is, Syphilis Symptoms in Infants, because pregnant women with syphilis may transmit syphilis to their children, and infants suffering from syphilis may have the following symptoms:

Intermittent fever;

Enlarged spleen and liver (hepatosplenomegaly);

Lymphatic enlargement;

Prolonged sneezing and runny nose with no obvious allergens (persistent rhinitis);

Mottled papules on the hands and soles of the feet.

Syphilis is actually not a particularly serious disease, early detection can be cured early. If you want to prevent it, I think we should all know, we all know in our hearts, is to pay more attention to men and women that. Also, syphilis is not spread through **** with objects, such as door knobs, toilets or swimming pools, etc., this point I hope you can have a correct cognition.

If you suspect you have syphilis, don't hesitate to seek medical attention.
