Germs Facts: Understanding the Invisible Threats Around Us


Germs are invisible tiny organisms that exist all around us. They are not living creatures, but they can cause havoc on our health and wellbeing. We cannot see them with our naked eye, but they exist on surfaces we touch, in the air we breathe, and even inside our bodies. If ignored, they can cause severe illnesses and diseases that can be life-threatening. In this article, we will explore different germ facts that will help you understand the invisible threats around us.

What are Germs?

Germs are tiny organisms that can exist in different forms – bacteria, viruses, fungi, and parasites. They are found everywhere – on surfaces, in water, soil, food, and air. While some germs are harmless, others can cause serious illnesses and infections. They enter our bodies through different means – breathing, touching, eating, and drinking. Once inside our bodies, they can multiply and spread rapidly, causing severe damage to our organs.

Types of Germs

There are four main types of germs – bacteria, viruses, fungi, and parasites.

– Bacteria: Bacteria are single-celled organisms that exist in different shapes and sizes. While some bacteria are beneficial, others can cause infections and diseases such as pneumonia, tuberculosis, and strep throat. They can be found on surfaces, in water, and even in our bodies.

– Viruses: Viruses are tiny infectious agents that exist in different shapes and sizes. They can cause a variety of illnesses, ranging from the common cold to more severe diseases such as COVID-19. They can spread through the air, touching, and close contact with infected people.

– Fungi: Fungi are multi-cellular organisms that exist in different shapes and sizes. Some fungi are beneficial, while others can cause infections such as athlete’s foot and ringworm. They can be found in soil, water, and on surfaces.

– Parasites: Parasites are organisms that live on or inside other organisms and harm them. They can cause a variety of illnesses ranging from malaria to tapeworm infections. They can be found in contaminated food, water, and soil.

How do Germs Spread?

Germs can spread in different ways –

– Touching contaminated surfaces: Germs can live on surfaces, such as doorknobs, handles, and countertops. If we touch these surfaces and then touch our faces, we can transfer the germs into our bodies.

– Inhalation: Germs can spread in the air and cause infections. This is especially true for respiratory viruses such as COVID-19.

– Eating contaminated food: Germs can contaminate food and cause food poisoning.

– Drinking contaminated water: Germs can exist in water and cause waterborne diseases, such as cholera and typhoid fever.

How to Protect Yourself from Germs?

There are several ways to protect yourself from germs –

– Wash your hands regularly: Washing your hands with soap and water for at least 20 seconds can help kill germs.

– Use hand sanitizer: If soap and water are not available, use a hand sanitizer that contains at least 60% alcohol.

– Cover your mouth and nose: When coughing or sneezing, cover your mouth and nose with a tissue or your elbow.

– Avoid close contact: Avoid close contact with people who are sick.

– Disinfect surfaces: Disinfect frequently touched surfaces such as doorknobs, handles, and countertops.
