Who hasn’t got an infection? all of us have! Today let’s understand the real science and meaning behind an infection. Infection is the conquering of an organism’s body tissues by any kind of germ like bacteria, virus, fungus, etc. When a germ enters our body, they multiply in number and cause several reactions in our body.

There are 3 things necessary for an infection to occur:

  • Source: The place/person from where you catch the infection( eg. surfaces, washrooms, handshake)
  • An easy-to-target person: helps them to enter the body without many obstacles.
  • Spread of the disease to the person. Germs don’t move, they depend on people or the environment to start the transmission.

After the germs multiply in our body, they target a body tissue or organ and start killing it. Meanwhile, our body’s immune system gets awakened and it tries to fight back with the germ, and we experience certain symptoms of the particular disease.

There are 5 types of infections, viz; bacterial, protozoan, fungal, viral, and par, ascetic worms. The most common type of infection is caused by either bacteria or viruses.

  • Bacterial infections include pneumonia caused by Streptococcus pneumonia, Tuberculosis caused by Mycobacterium tuberculosis, meningitis(swelling of the brain) caused by Neisseria meningitides, Urinary tract infections, skin infections, etc

2. Viral infections include common cold caused by the rhinovirus, COVID-19 caused by a coronavirus, skin infections and warts caused by HP virus, polio caused by poliovirus, influenza flu, etc

3. Fungal infections include mucormycosis caused by mucor fungi, candidiasis caused by candida fungi, athletes foot

4. Protozoan infections include African sleeping sickness caused by the tsetse fly, amoebic dysentery caused by Entamoeba histolytica, malaria caused by plasmodium, etc

5. Worm infections include common water-related diseases are caused by guinea worm, schistosomiasis, giardiasis, etc

Signs of infections

Some general signs of infections are fever, chills, sweats, stuffed or runny nose, headaches, sore throat, tiredness, body ache, joint pain, etc


Here are some general ways to prevent infection :

  • Washing hands well with a handwash or even a sanitizer frequently to avoid being contacted with germs
  • cover your mouth while coughing or sneezing to prevent others from getting the disease( don’t be selfish lol)
  • Always cover open wounds or blemishes and never squeeze pimples
  • Don’t share the personal stuff like bath towels, soaps, creams, razors, etc ( sharing is not caring in this case)
  • Rinse all meat, poultry, fish, fruits, and vegetables under running water before cooking or serving them.
  • Do not eat foods that are refrigerated for more than 3 days (unless they contain preservatives)
  • Get vaccinated for all the necessary diseases.
  • keep the surroundings clean by using disinfectants.

Although prevention is better than cure, in case you get an infection here’s what you can do (even though different infections have different medications):

  • Doctors/Health officers usually prescribe oral antibiotics to kill the underlying germs in the body.
  • in addition, natural immunity boosters like citrus fruits, ginger, lemon, curds, nuts, etc can be taken to fasten the healing process
