There are so many kinds of Infectious diseases, depending on the type of organism that attacks the body. Although not all organisms are classified as dangerous, but will still cause health issues that make everyday activities uncomfortable. Besides, the cause can occur in various ways such as direct contact, through food consumed, or through contact with objects around. To find out more about the types of infectious diseases, let’s look at some types of infectious diseases that usually attack humans.

HIV / AIDS

This HIV AIDS is a deadly malignant disease. HIV stands for the Human Immunodeficiency Virus, while AIDS is Acquired Immunodeficiency Syndrome. From the name, it is clear that this disease is caused by a virus that attacks the human body’s immune system.

Although most diseases are related to the immune system, this is very dangerous because it can be fatal. Sequentially, the virus attacks white blood cells, commonly called T lymphocytes. If the development of white blood cells is damaged, then the antibody will be disrupted.

Pneumonia

Pneumonia may not be as popular as cancer. But, it does not mean this disease can be underestimated. Pneumonia, which is often referred to as wet lung or pneumonia, is characterized by an infection of one or both lungs that is usually caused by bacteria.

Meningitis

One of the diseases that attacks the brain is meningitis. Meningitis is often referred to as inflammation of the lining of the brain. More clearly, meningitis is a disease that arises due to inflammation of the meninges, which is a protective layer whose role is to envelop the brain and spinal cord. The inflammation is mostly caused by fungal infections. Virus infection may occur due to the food consumed. As a result, inflammation causes nerve and brain damage due to swelling. In addition, meningitis can also be contagious.

Kidney Failure

A kidney is one of the important organs in the body whose role is to filter and cleanse the blood of foreign substances and compounds that enter the body. However, an unhealthy kidney will cause a dangerous disease that is kidney failure. Bacterial and viral infections such as hepatitis A, B or C, strep throat, and urinary tract infections can cause sudden inflammation in the kidneys which ultimately results in kidney failure.

Polio

Polio is a disease caused by the genus enterovirus. This virus enters through the mouth, then infects the intestinal tract. After that, it enters through the bloodstream and attacks the central nerve causing permanent paralysis within hours. Polio can be transmitted through human contact, through feces or virus-contaminated feces. Usually, if one family member is infected, then other family members will also be infected. People infected with this virus will experience muscle weakness and can cause paralysis, especially in the legs. In toddlers prone to polio, because the immune system is not as strong as adults.

Measles

The cause of measles is in the form of an RNA virus, which is a virus whose genetic material is nucleic acid in the form of twisted chains. This virus is still classified as the Paromyxavirus family. If the HIV virus is transmitted by contact, Measles is transmitted through the respiratory tract.
