Infectious diseases: main signs, symptoms, preventive measures

Methods of infection

Any disease cannot appear out of nowhere: infection occurs through airborne droplets through various objects or is carried by insects and animals. As for intestinal diseases, they are transmitted orally.

Bacteria and viruses are found on all surrounding objects and can get to you with dirty food, poorly washed hands, food that has spoiled in the heat and has not been heat treated.

When pathogens enter the body, they multiply intensively, which subsequently leads to illness. Infections of this kind resemble poisoning in their symptoms, because during the life of bacteria enterotoxins are released, which affect the balance of salts in the body and lead to their loss in the future.

Their pathogens are:

• entero- and rotaviruses;
• bacteria (salmonella, staphylococcus).

Possible diseases:

• dysentery;
• rotavirus infection;
• cholera;
• salmonellosis.

Each of them has its own incubation period, which can last from 6-7 hours to several days.

The main signs of intestinal diseases are diarrhea, nausea, vomiting, abdominal pain and fever.

If even some of them occur, you need to see a doctor and not let the disease get out of hand. Treating an infection at an early stage of development is much faster and easier.

How to prevent the disease

What can help a person avoid intestinal diseases? First of all, personal hygiene. Do not forget about the most basic thing - wash your hands before each meal. Many people remember from biology that human gastric juice and saliva have bactericidal properties. This means that by thoroughly chewing food, you reduce the risk of microbes entering the gastrointestinal tract, and this also promotes digestion. The mucous membrane also serves as a special protection, it contains beneficial microorganisms that protect the intestines from bacteria.

The body's susceptibility to infection is also affected by general health, immunity and even lifestyle. Constant stress, uncontrolled use of antibiotics and unbalanced nutrition are very harmful to health and make the body susceptible to various viruses. To avoid diseases, you need to lead a healthy lifestyle and strengthen your immune system.

But if you still fail to protect yourself, remember: any infection, especially intestinal, is quite dangerous, so you should not try to cope with it on your own, you need properly selected medications and observation by an infectious disease specialist.
