Your health: how to protect it

Every day your body fights a war against silent and invisible, but potentially deadly enemies. Like invaders, bacteria, viruses and parasites threaten your health *. You may not be aware of the battles within you, because your immune system repels or destroys most attackers even before symptoms appear. However, pathogens sometimes take over. You must then strengthen your immune system with medical treatment.

 

Four factors of illness: travel, microorganisms, poverty and poorly prepared food

For centuries, people knew next to nothing about the dangerousness of microbes and other small pathogens. But in the 19th century, scientists confirmed a link between germs and disease, which made us better equipped to defend ourselves. Since then, researchers have eliminated, or greatly reduced, the threat of certain infectious diseases, such as smallpox and polio. Recently, however, other diseases, such as yellow fever and dengue fever, have reappeared. Why ? Let us cite four factors.

 

Each year millions of people travel the world, many carrying pathogens. According to an article in the journal Clinical Infectious Diseases, international travelers can facilitate the spread of "almost all virulent contagious infections *".

 

Some bacteria have become resistant to antibiotics. "The world is moving into a post-antibiotic era, in which common infections ... may start killing again," says the World Health Organization (WHO).

 

Civil unrest and poverty often hamper efforts by governments to control the spread of disease.

 

Many people do not know how to protect themselves from disease.

 

Despite these disturbing facts, there is a lot you can do to protect yourself and your family. The following article will show that even if you live in a developing country, there are simple and effective prevention options available to you.
