Читать книгу 100 Ways to Boost Your Immune System - Theresa Cheung, Theresa Cheung - Страница 10

Diseases and infections are not the same thing. Infection is the first step to disease when bacteria, viruses or other antigens enter your body and try to multiply and take hold. Disease or illness occur when the cells in your body are damaged by infection, and signs and symptoms of illness will become evident.

Common symptoms of infection, such as sweating, chills, fever, runny nose, sore throat, coughing and sneezing, are all indications that your immune system is doing its job and fighting back. In most cases the natural healing response your immune system offers is effective in warding off invading antigens but sometimes things don’t work so efficiently. Bacteria, a virus or other antigens make it past your immune defences and you get ill. And the most common way to get ill is with a cold or flu virus.
