Contagious diseases are diseases that can be transmitted or passed from people who are sick to a healthy person or have not been exposed to the contagious disease. The transmission of the disease can occur both through intermediaries and direct.
Contagious disease groups
Contagious diseases caused by an infectious agent or toxic product of a person or animal can occur either directly or indirectly.
There are three main groups of contagious diseases, namely:
- The disease is very dangerous because the mortality rate is high
- Certain contagious diseases cause death and disability, although the result is lighter than the first.
- Contagious diseases rarely lead to death and disability, but can cause epidemics that raise material and health losses.
Contagious Disease Lists
Here are some list of contagious diseases that we can summarize for you:
Influenza or more commonly known as the flu are the most common contagious disease suffered by people. Influenza is caused by viruses. The influenza virus is a virus that at any time mutates, so the immune system is difficult to detect these viruses. Because of the difficult body immune system to detect this influenza virus, the body tends to be prone to flu. Even the body can be several times gets the flu at the adjacent time.
The Flu can be transmitted through the respiratory system also through saliva. So if we are close to the flu person, chances are we are infected with the flu is very large. Air intermediaries are the most rapidly transmitted media of the flu.
How to prevent it
Keep your body immune from being easily infected by viruses. For example with regular eating, adequate rest, drink water as needed, exercise, and have a healthy lifestyle.
In addition, maintaining endurance can also be supported by vitamin C intake, which can be obtained in both fruits and vitamins sold in stores.
Another precaution is to use masks in the public place, especially for those suffering from influenza.
Acute respiratory tract infections (ARI)
Respiratory tract infections can attack the nose, throat, airway, and lungs. ARI begins with fever accompanied by one or more symptoms of sore throat or swallowing pain, dry or phlegm cough, and colds. This condition is often caused by viruses, but can also be caused by bacteria.
The ARI caused by viral infections will usually improve within 3 – 14 days. ARI can be prevented by behaving a clean and healthy life, familiarizing hand washing. Observe the ethics of coughing and sneezing, and use masks to prevent viruses and bacteria from spreading to others.
Diarrhea is a disturbance of bowel movements. The disease is characterized by a bowel movement more than three times a day or frequent bowel movements, accompanied by a sense of heartburn, with the consistency of liquid stool, and can be accompanied by blood and or slime.
Diarrhea may be considered trivial when it can be potentially death, especially in infants. Diarrhea is transmitted through water, soil, or food contaminated by viruses, bacteria, or parasites.
Tuberculosis (TB) is a highly contagious infectious disease that primarily attacks the lungs. According to the World Health Organization (WHO), TB is one of the top 10 causes of death globally, killing 1.7 million in 2016. TB is a preventable and cured disease with proper treatment.
What are the symptoms of TB?
Some people are infected with the Mycobacterium bacteria tuberculosis cause TB, but do not experience symptoms. This condition is known as latent TB. TB can settle in the body in an inactive state for years, before it develops into an active TB disease.
Active TB usually causes some symptoms. The clinical symptoms of active pulmonary TB are:
- Cough more than 3 weeks
- Cough with phlegm or blood
- Night Sweats
- Fever without a clear cause
- Weight loss
- Unexplainable fatigue.

Typhus is a group of infectious diseases that include various types of fever caused by the bacterial infection of Salmonella typhi. These bacteria can be carried by an ectoparasitic like lice and mites that then infect humans.
These bacteria are usually often found in animals such as mice, cats, and squirrels. These bacteria can also be carried away through clothing, sheets, skin, and hair.
To prevent typhoid can be done by avoiding direct contact with the sufferer for a long period. Also avoid the habit of using personal belongings together. If necessary, consume the antibiotic prescribed by the Doctor and follow the instructions.
Pneumonia is a deadly contagious infection that can be caused by either bacteria, viruses, or fungi. This disease can be very serious and deadly if not treated immediately.
This deadly contagious disease caused the body to produce white blood cells to fight infections, so inflamed lungs and bacteria and viruses precisely fills the air sacs in the lungs with fluid.
Although it can affect people of all ages, the disease is generally more risky for toddlers, seniors, and people with poor immune systems. This infection is transmitted through cough, sneezing, or physical contact with objects that are touched by people with pneumonia.
The disease is still curable. The healing can be done based on the cause:
- Pneumonia that occurs because bacteria can be treated with antibiotics.
- Viral Pneumonia can be treated by increasing body endurance, resting and increasing fluid intake into the body.
- Pneumonia caused by fungal infections can be treated with anti-fungal drugs.
