An infection (Latin infectum - to nourish, to infect) is a disease caused by the penetration into the body and the reproduction in it of pathogenic microorganisms - bacteria, viruses, fungi, protozoa.
The infectious process begins with the penetration of the pathogen into the human or animal body. This is followed by the stage of reproduction of the microorganism, during which tissue damage occurs and the normal functioning of organs and systems is disrupted. This leads to the development of an inflammatory reaction and the appearance of symptoms of the disease.
Infectious diseases differ from non-infectious diseases in that they are transmitted from a sick person or animal to a healthy one. The routes of transmission are varied - airborne, fecal-oral, sexual, blood, etc.
Prevention of infectious diseases includes sanitary and hygienic measures, vaccination, and timely treatment of patients. Infection control is an important public health task.
Infection is a term used in medicine and biology to refer to the infection of an organism by microorganisms. The term is of Latin origin and means “to infect.” In the context of medicine, the concept of infection involves the presence of harmful microorganisms in the body that can cause various diseases and symptoms.
Infections are among the most common diseases in the world. They can be caused by a variety of microorganisms, including bacteria, viruses, fungi and parasites. There are many forms of infections. For example, acute infections such as the flu or chickenpox can occur quickly and cause severe symptoms. Chronic infections, such as tuberculosis, can last a long time and cause many complications.
Factors that increase the risk of infection include a weakened immune system, chronic illness, poor diet, smoking and alcohol consumption. Prevention includes general health maintenance, proper nutrition and a healthy lifestyle. If you notice any symptoms of the disease, you should consult a doctor.
Diagnosis of infections includes medical history, laboratory tests, x-rays and other diagnostic methods. Treatment of infections depends on the form and severity of the disease. Medicines may include antibiotics, antivirals, and antifungals. Sometimes surgery is required.
The importance of infection prevention is evidenced by the fact that there are a large number of infections that are spread through blood and the infection of which can lead to death. This is especially true for sexually transmitted infections. It could be HIV or syphilis. Vaccination also plays a significant role
