It is also called the "stomach flu." Disrupting the gastrointestinal tract, it carries the danger of dehydration of the body. The main thing is to detect the disease in time to prevent a critical condition. The level of modern medicine makes it possible to treat this virus. But in countries where medical care is poor, 61,000 people die each year. Very often this infection is called "dirty hands disease".
9. Arboviruses of the Flaviviridae family
They are dangerous because they can cause Dengue fever, which is accompanied by pain in the spine and joints, especially the knees. The patient's body temperature rises, chills, nausea appears. The skin becomes covered with a rash. If the disease is severe, it can cause death in up to 50% of cases. A person becomes infected mainly through an insect. Therefore, you should carefully examine your skin after a walk in the woods.
8. Virus of the family Flaviviridae
Very often this virus provokes the appearance of a disease called "yellow fever". This disease is caused by the bite of mosquitoes that live in the subtropics of Africa and South America. The patient develops jaundice. The liver fails to cope with its function, and in most cases death occurs. Special ointments, aerosols, sprays are not bad protection. Tourists visiting countries inhabited by mosquitoes can be vaccinated to support the body.
7. Hepatitis C virus (HCV)
Very often it is called the "gentle killer" because the disease develops and there are no symptoms. A person feels good, does not suspect anything about the presence of the terrible virus in the body. The disease progresses and becomes chronic. The virus cannot be cured, there is no vaccine. The infection affects the liver. Infection occurs through blood. Prevention - sterilization of medical and cosmetic instruments, observance of personal hygiene rules, exclusion of unfamiliar sexual partners.
6. Hepatitis B virus (HBV)
Sometimes a carrier of the virus does not suffer from a disease that destroys the liver. However, he or she does pass the infection on to others. The virus is very resistant to high and low temperatures. It persists for a long time in blood stains, on the end of a needle, on a razor blade. It is perfectly transmitted by household (sharing towels, toothbrushes, razors) and by injection, when several people are served with the same needle. Good personal hygiene, avoiding promiscuity, is the best protection against this terrible virus.

3. Human immunodeficiency virus
It is called the "plague of the 20th century." This infection simultaneously affects all human organs and destabilizes their functions. The immune system ceases to protect the body, and any minor illness may be fatal. Scientists have not yet found a vaccine that would be a reliable barrier to this virus. We can only hope for prudence of people who want to avoid the dangerous disease. Careful choice of sexual partners, avoidance of drugs.
2. Rabies virus.
This infection is completely indiscriminate. Affects humans, domestic and wild animals. It is transmitted through saliva. First symptoms are the appearance of fear, depression, later hallucinations.
