Meaning, Types, Treatments, Symptoms and Controls of Infections


When a microorganism enters a person’s body and causes harm what occurs is an infection. An infectious disease is when germs get into the body, increase in the body in number and cause a sensitive and harmful reaction in the body.

Types of infections

There are different types of infections and some of them that will focus on the most common and deadly types of infection: bacterial, viral, fungal, and prion will be discussed in this article.

1. Viral infections

Viral infections are infections occurring as a result of a virus. There are millions of viruses existing, though not more than 5,000 types were identified up to date.

Viral diseases usually contain a genetic code and a piece of protein and fat molecules. Viral infections are an item of information within a protective shell.

There are many examples of viral infections such as encephalitis, meningitis, COVID-19, gastroenteritis, herpes, warts, HIV, hepatitis C, polio, zika virus, influenza (flu), Ebola, etc.


Antiviral medications may assist to relieve the symptoms of some viruses while the disease passes. Antiviral drugs can either prevent the virus from reproducing or boost the host’s immune system to counter the effects of the virus.

Be informed that antibiotics cannot cure viruses. Therefore, most treatments are aimed to relieve symptoms while the immune system combats the virus without any assistance from medication.

It is possible for you to manage most viral infections with over-the-counter medications for your symptoms until you feel better

2. Bacterial infections

Bacterial infections are tiny organisms with instructions written on a small piece of DNA. Bacteria can be found both on the skin and inside our bodies. Though many bacterial infections are dangerous, certain bacterial infections release toxins.

Research has it that bacterial infections tend to live virtually in any type of environment, from extreme heat to intense cold. It has been found that there are trillions of strains of bacterial infections but few of them cause diseases in humans.

There are examples of bacterial infections such as cholera, diphtheria, dysentery, typhoid, tuberculosis, typhus, bubonic plague, bacterial meningitis, otitis media, pneumonia, gastritis, eye infections, food poisoning, skin infections, sexually transmitted infections (STIs), urinary tract infections (UTIs), upper respiratory tract infection, sinusitis, etc.


Antibiotic medications are effective against bacteria Doctors can indeed treat bacterial infections with antibiotics.

This is because some strains, however, become resistant and can survive the treatment. Bacterial infections can be treated with antibiotics.

3. Fungal infections

Similar to bacteria, there are different fungal infections. They live both on and inside the body. When your fungi infections get overgrown into the body system through the mouth, your nose or a cut in your skin will get sick.

Approximately, up to 5.1 million fungi species, the body usually has a population of good bacteria that help maintain the balance of microorganisms.

This lines the intestines, mouth, vagina, and other parts of the body. There are examples of fungi infections such as candidiasis, valley fever,  histoplasmosis, athlete’s foot, ringworm, eye infections, thrush, fungi nail infections, etc.


Antibiotics can be effective if it is used for a long time. It is important to build your immune system, especially for those living with HIV or diabetes or receiving chemotherapy treatment.

4. Parasitic infections

Parasites that use the bodies of other organisms to live and reproduce are called parasite infections Parasitic infections include worms (helminths) and some single-celled organisms (protozoa). There are other examples such as giardiasis, toxoplasmosis, hookworms, pinworms, etc.

Symptoms and causes of infectious diseases

1. Symptoms

Symptoms of infectious diseases are concerned with the illness. Most local symptoms such as rash and itching are caused by fungal infections.

Viral and bacterial infections have symptoms in many areas of the body such as fever, cough, fatigue, congestion, muscle aches, headaches, chills, diarrhea, nausea, vomiting, etc.

2. Causes

Various agents cause infectious diseases to invade the body from the outside. The agents include the following: viruses, bacteria, fungi, parasites, prions, etc.

When your cells are damaged or destroyed caused by the invading organism and as your immune system responds to the infection, then there is tendency for you to develop symptoms.

4. Disinfect rooms having high bacterial concentrations.

This is important to disinfect rooms that may have high concentrations of bacteria including the kitchen and the bathroom and reduce the risk of sexually transmitted infections (STIs) by receiving regular STI checks.
