What are the types of infectious diseases?

Hemorrhagic fever is a group of diseases of viral origin, accompanied by signs of a feverish state: elevated body temperature, vascular damage, the occurrence of hemorrhagic syndrome.

Hepatitis D is a severe and dangerous disease that affects the liver and is viral in nature. It is a concomitant disease of hepatitis B.

Hepatitis A (called Botkin's disease) is the most common liver disease. It is quite mild and treatable, with virtually no consequences for a person.

Hepatitis B is a liver disease caused by an anthroponous viral infection that affects the liver. The disease has many clinical manifestations: it can be asymptomatic or lead to the destruction of the liver parenchyma. During the inflammatory process, autoimmune damage to liver cells is observed.

Hepatitis E is an acute viral disease that is dangerous to human life. It has a fecal-oral type of infection.

Hepatitis C is the most severe form of viral hepatitis. This is a viral anthroponotic disease with a parenteral mechanism of infection, most often occurring as post-transfusion hepatitis. It does not have icteric forms, and tends to become chronic.

Flu is an acute viral disease of humans, primarily affecting the respiratory tract and cardiovascular system, and is spread in an epidemic manner.

Acute osteomyelitis is a disease characterized by bacterial inflammation of the bone marrow and all structural elements of the bone. Appears after injuries or surgery.

Panniculitis is an infectious pathology of the skin and subcutaneous tissues.

Human papillomavirus (HPV, genital warts) is an infectious disease characterized by the development of papillomatous formations on the skin and mucous membranes. In most cases, it can recur, spread widely, and is highly contagious.

Paragnizure is an acute viral disease, the course of which is accompanied by damage to the upper respiratory tract (mainly the larynx) and is characterized by mild intoxication of the body.

Paratyphus A and B are acute infectious diseases that are similar in their symptoms to typhoid fever.

Paratonsillitis is a severe infectious disease characterized by acute inflammatory-purulent processes in the peritonsillar tissue.

Inguinal lymphadenitis is a type of lymphadenitis characterized by the occurrence of inflammatory processes of the lymph nodes in the groin area.

Axillary lymphadenitis is an inflammation (usually purulent) of the lymph nodes in the axillary region. It is usually caused by staphylococcal and streptococcal flora that enter the lymph nodes.

Submandibular lymphadenitis is a process in which the lymph nodes located under the lower jaw become inflamed.

Leprosy is a disease caused by an infection that affects the skin and peripheral nervous system of a person.

Pseudotuberculosis, or Far Eastern scarlet fever-like fever, is an acute infectious disease of the gastrointestinal tract, liver and skin, which is characterized by an intoxication-febrile state of the body. The causative agents of the disease are pseudotuberculosis bacilli.
