Talking About Infectious Diseases


Infectious diseases are those caused by microbes. They can be viruses, bacteria, fungi, or protozoans. The most common infectious diseases are viral and bacterial infections. Some infections can spread from one person to another through water, bugs, contaminated food, or person to person.

You should never take infections lightly because they can turn into sepsis, leading to shock. The most common symptom of an infection is fever, therefore if you have the same complaint, you must seek professional help.

To treat bacterial infections, your healthcare providers would prescribe antibiotics. Make sure you take them on time and do not skip any dose. Always take antibiotics in the dose your healthcare provider prescribes. If you do not take it properly, it can result in antibiotic resistance.

Pathogens can enter our bodies through openings, such as the mouth, nose, eyes, ears, anus, urethra, or vagina. When they enter inside your body, they replicate and cause an infection. If your skin is damaged due to any cut or abrasion, the microbes can have an easy entrance into your body.

What Is The Difference Between Infectious And Non-Infectious Diseases?

Infectious diseases are those you get from pathogens such as viruses, bacteria, fungi, and protozoa. There is always an external causative agent in it. Non-infectious diseases do not occur due to pathogens. Instead, they may occur due to genetic or anatomical defects. You do not get non-infectious diseases from other people. They are non-transmissible.

The common examples of infectious diseases are COVID-19, urinary tract infection due to E.coli, typhoid, HIV, measles, mumps, and others. And common examples of non-infectious diseases are congestive heart failure, hypertension, diabetes, cancer, Alzheimer’s disease, and others.

What Are The Types Of Infectious Diseases?

Infectious diseases are differentiated based on the organism causing the disease. There are four types of microbes that we can not see from our naked eyes, and they can enter your body and cause an infection. They are named bacterial, viral infections, fungal and protozoal infections.

Who Is At Most Risk Of Getting Infections?

The risk of getting an infection remains for everyone. But some people are at increased risk for it. Often it happens when your immune system is compromised due to various reasons. It can happen due to long-term immunosuppressant intake. You have to take them if you have had an organ transplant. Moreover, you might also need to take immunosuppressants if you have immune system conditions, such as asthma, allergies, or systemic lupus erythematosus.

Your healthcare providers will prescribe it based on the risk versus benefit ratio. People who have HIV are at increased risk of getting infections- more commonly known as opportunistic infections. They occur when your immune system can not fight well against microbes. Unvaccinated people are also at increased risk of getting infections. When you get vaccinated against a certain organism, the risk of catching it is lowered. Young children, people over the age of 60, and pregnant women are at increased risk of getting infections.

Healthcare workers who serve patients day and night can easily catch the organism and get an infection. It is quite common in respiratory tract infections. If you travel to areas where typhoid, malaria, or dengue is prevalent, you might also get it.

How Can You Prevent Infections?

Infections are not totally preventable, but they can be up to some extent. For that, you need to play an essential role. Do the following things to stay healthy.

  • Get yourself and your family vaccinated on time. Make sure whenever the vaccine is due, you plan for it.
  • Wash your hands frequently with soap and water, especially when you come home from outside.
  • Eat food that is freshly and fully cooked. Do not eat old and undercooked food. Also, keep it in the refrigerator so that it remains fresh.
  • Wear a mask when visiting someone with a respiratory tract infection.
  • Drink treated water. Avoid drinking tap water in places where typhoid is prevalent.
  • Take all the medicines including prophylaxis antibiotics as prescribed by the healthcare provider.
