B. syphilis

Explanation:

Syphilis is an STI, ie a sexually transmitted infection. This means that the infection is transmitted mainly through condomless sexual intercourse. It can also be transmitted from mother to baby during pregnancy. It is caused by the bacteria Treponema pallidum.

This disease is divided into three stages of infection, the first stage being the simplest to treat but is characterized by the emergence of a hard base ulcerated wound that usually arises at the site of infection. The wound is painless, yet produces a highly infectious fluid that can infect other people.

The second stage is represented by major damage characterized by small wounds on the skin (especially the palms) and mucous membranes. Any surface of the body can be affected by these lesions that carry a large amount of bacteria and are highly infectious. Other symptoms include low fever and malaise.

The third stage is represented by severe symptoms. At this stage, the disease can cause paralysis, seizures, heart disease, organ failure. Injuries at this stage can cause extensive tissue damage, leading to perforation of the roof of the mouth and impairing speech. They can also cause disfigurement and disability and can be fatal. It is common for the nervous and cardiovascular systems to be impaired.
