Learn More About Infection : Go Down to Important Basics

You may often hear the word ‘infection.’ But do you know what happens when there is an infection? Most people think of it as ‘disease.’ They don’t care what it is as long as they get treatment.

However, having some in-depth knowledge about infections can be useful. For example, understanding the causes will help you prevent it. Also, studying symptoms will help you identify the infection during the initial stages.

So to help you, here is a list of some basic information about infections – this is relevant information and can help:


Infection is the body’s reaction to the invasion of microorganisms that cause disease. Infection may be a direct reaction from the body to the presence of organisms. That might also be the result of poisons produced by invaders.

Most people also believe that microorganisms such as viruses and bacteria only cause infection. However, infections can also be caused by larger organisms such as fungi, protozoa, and macroparasites.


The body can manifest different symptoms depending on the cause of the infection, the part of the body affected, and the severity of the condition. However, some common manifestations include fever, inflammation, pus, cough, and others.

But sometimes, the infection lies deep within the body (intestines, organs, passageways, etc.). In this case, symptoms may not be observed. Generally, asymptomatic infections are called ‘occult infections.’


Infection occurs because your body is fighting an invasion. This means it’s only a matter of time until your body gets rid of the infection. But this is just the case with non-malignant infections.

Sometimes, the body needs help fighting infections – this is why you go to the doctor. Some are easily cured and do not last long (acute). But some are more troublesome and need time to cure (chronic).


The drugs given to treat infections differ from one case to another. Treatment is different depending on the cause of the infection. However, most of the drugs given are antibiotics.

Penicillin is one of the most famous anti-infective drugs. This can be given orally and topically. Oral penicillin intake is intended to cure internal infections. Topical application of penicillin, on the other hand, is used to treat external infections (e.g., infected wounds).


Prevention usually consists of two parts: 1) adapting practices that prevent infectious microorganisms from entering the body and 2) strengthening the immune system so that it can fight disease-causing organisms when coming to the body.

The first part emphasizes good hygiene practices above all. The second part might include intake of food supplements and adaptation to a healthy lifestyle (getting enough sleep, eating healthy food, practicing safe sex, etc.).

And this is just some basic information about infections. Of course, you can expand your research to help you fight infections more effectively. This information will be beneficial for you and your family.
