Question

How does a pathogen enter the body?

Answer 1

Hint: A pathogen is a disease-causing organism. Microbes are found in abundance in your body. These microorganisms, on the other hand, only become an issue if your immune system is compromised or if they enter a typically sterile portion of your body. Pathogens are different from bacteria in that they can cause disease if they enter the body.

Complete answer:
A pathogen just needs a host to flourish and survive. The infection avoids the body's immune reactions and uses the body's resources to replicate before exiting and spreading to a new host once it has established itself in the host's body.

Depending on the pathogen, it can be spread in a variety of ways. Skin contact, bodily fluids, airborne particles, contact with faeces, and touching a surface touched by an infected person are all ways they might spread.

Pathogen classifications:-
- Pathogens come in a variety of forms, but we'll focus on the four most common: viruses, bacteria, fungi, and parasites.
- Viruses are made up of a bit of genetic information (DNA or RNA) that is protected by a protein coating. Viruses infect host cells in your body once you've been infected. They then multiply using the components of the host cell, producing additional viruses.
- Bacteria are microorganisms that are made up of only one cell. They come in a wide range of forms and sizes, and they can live in just about any environment, including within and on your body. Infections aren't caused by all bacteria. Pathogenic bacteria are microorganisms that can cause disease.
- On the planet, there are millions of distinct fungus species. Only about 300 trusted sources are known to cause illness. Fungi can be found in almost any habitat, including indoors, outdoors, and on people's skin. When they outgrow their confines, they spread infection.
- A nucleus and other components of fungi cells are protected by a membrane and a thick cell wall. They may be more difficult to kill due to their structure.

Parasites are microorganisms that live in or on a host and feed on or at the expense of the host. Despite the fact that parasite diseases are more common in tropical and subtropical areas, they can happen anywhere.

Note: The following are some techniques to keep yourself and others safe from infections. Hands should be washed frequently, Vaccinate yourself and make sure your immunizations are up to date, Meat and other foods should be properly prepared, cooked, and stored, When you're unwell, especially if you have a fever, diarrhoea, or are vomiting, stay at home, Personal things such as razors and toothbrushes should not be shared.
