Necrotic fasciitis is an infection that affects the subcutaneous tissue and fascia. (Fascias are membranes of connective tissue covering all organs, vessels covering muscles, tendons.) The disease is very dangerous, and if it is launched, it can even lead to death.
Causes of necrotic fasciitis
The disease is caused by pathogenic bacteria that have come under the skin from the outside: from a wound, cut – or from the inside: along with blood flow. As a result, an infectious process develops right under the skin and tissue destruction occurs. Most often, the legs are affected, as well as the perineum and abdominal wall, but the infection can affect other parts of the body.
Various bacteria can be causative agents, but pyogenic streptococcus Streptococcus pyogenes is especially Continue reading
HPV, also known as human papillomavirus, is a family of viruses that live in the epithelial cells of the human body and under certain conditions cause their rapid division and degeneration. As a result, such unpleasant formations as warts, papillomas, and condylomas grow on the skin. But this is not the worst when infected with papillomavirus. Scientists have found that HPV can trigger the development of a cancerous tumor.
Of course, this does not mean at all that if a person is found to have HPV, then he will certainly get cancer. Moreover, the papillomavirus, according to some sources, affects about 60-70% of the world’s population, and according to others – 90%. Continue reading
Rabies is an acute infectious disease of humans and animals caused by the rabies virus – rhabdovirus. Rabies virus leads to severe damage to the nervous system – specific encephalitis and, as a rule, ends with the death of the patient – after the onset of symptoms of the disease, there is no chance of salvation. Prevent the development of the disease can only urgent vaccination immediately after infection.
How rabies virus infection occurs
The main carriers of rabies virus are animals: both wild – wolves, foxes, rats, and agricultural, domestic and homeless – cows, dogs, cats. Theoretically, any warm-blooded animal, including humans, can be a virus carrier. But in most cases, a person is infected with a bite of a sick dog. Continue reading
