Understanding Infectious Diseases

Infectious Diseases

Tiny germs that can make people sick cause catching diseases. We call diseases caused by bugs like viruses, germs, fungi, or sucker infectious diseases. Infectious diseases spread in different ways: directly or indirectly. Furthermore, local germs can cause toxic diseases if they enter various body parts. Overuse of drugs may kill bugs and cause toxic diseases. Infectious diseases may develop resistance, thus evading treatment. Germs sneak into our bodies in many ways. When they get in, they can cause problems. Let’s learn more about these diseases and how to stay safe.

What Are Infectious Diseases?

Germs cause infectious diseases. These diseases can spread from one person to another. When sick people cough or sneeze, tiny drops of germs fly into the air. If you breathe in these tiny drops, you might get sick too.

Germs can also hide on things like door handles and toys. When we touch these things, the germs can jump onto our hands. If we touch our faces, the germs can go inside our bodies.

Different Kinds of Germs

Two main types of germs cause infectious diseases: viruses and bacteria.

  1. Viruses: Viruses, on the other hand, are like tiny attackers. They enter our cells and make them do bad things. Consequently, they can cause the flu, colds, and COVID-19. Fortunately, vaccines can help protect us from some viruses.
  2. Bacteria: Bacteria are tiny living things. Some are good, but some are bad and make us sick. Antibiotics are medicines that can fight bad bacteria.

How to Stay Safe

Staying safe from infectious diseases is important. Here’s how you can protect yourself:

  1. Wash Your Hands: Use soap and water to wash your hands. Scrub for at least 20 seconds. This washes away germs on your hands.
  2. Cover Your Mouth: When you cough or sneeze, use a tissue or your elbow. This stops germs from flying into the air.
  3. Stay Away from Sick People: If someone is sick, therefore, try to keep your distance. Consequently, germs can jump from them to you.
  4. Vaccines: Vaccines are like shields for your body. Consequently, they make your body strong against some germs. Therefore, doctors give you shots to help your body fight these germs.

What Doctors Do

Doctors help when we’re sick with infectious diseases. They ask questions and sometimes do tests. Tests can show what germ is making you sick.

If it’s a bacterial infection, in that case, they might give you antibiotics. Consequently, these medicines kill bad bacteria. But if it’s a virus, like the flu, antibiotics won’t work. Viral infections need time and rest to get better.

Doctors also give vaccines to keep us healthy. When you get a vaccine, it’s like your body is practicing to fight germs. Then, if the real germs come, your body knows how to protect you.


Common Infectious Diseases

  1. Now, let’s talk about some common infectious diseases you might have heard of:
  2. Flu: The flu makes you feel sick. Moreover, you get a high fever, cough, and a sore throat. Fortunately, rest and fluids help your body fight the flu.
  3. Colds: Colds are like a milder version of the flu. Additionally, you sneeze a lot, have a runny nose, and feel tired.
  4. COVID-19: This is a new disease caused by a virus. It spreads easily, so it’s important to wear masks and get the vaccine to protect yourself and others.
  5. Chickenpox: Chickenpox gives you itchy red spots all over your body. Consequently, most kids get a vaccine to prevent it.
  6. Strep Throat: Strep throat makes your throat hurt a lot. However, doctors can give you antibiotics to help you get better.
  7. Tuberculosis (TB): TB is a lung disease that makes it hard to breathe. Additionally, it’s treated with medicines.

Final Thoughts

Infectious diseases are serious, but we can be superheroes by protecting ourselves. By washing our hands, covering our mouths, and getting vaccines, we create protective shields. Consequently, they keep us safe from those sneaky germs.
