Question

Name a disease which is caused by virus, bacteria and protozoa. Any two

Answer 1

Hint: Diseases are those that are transmitted from one person to another. These diseases are caused by microorganisms such as protozoa, fungi, viruses and bacteria that enter the body and cause a series of changes that lead to infection and damage to the body.

Complete answer:
Disease caused by virus
Viruses are very small infective agents. They are made up of a piece of genetic material, such as DNA or RNA, which is wrapped in a protein coat. Viruses enter cells in your body and use the cells' components to help them multiply. This also affects or kills infected cells.Viral disease is any disease or health disorder caused by a virus. Not that all viral diseases are contagious. This means that they're not always spread from person to person.Example : Common cold, HIV.

Disease caused by Bacteria:
Bacterial diseases include any form of disease caused by bacteria. Bacteria are a type of microorganism that are tiny forms of life that can only be seen through a microscope. Millions of bacteria usually live on the skin, in the intestines, and on the genitals. The vast majority of bacteria do not cause disease, and many bacteria are actually beneficial and are often referred to as 'good bacteria' or 'healthy bacteria.' Bacterial diseases arise when harmful bacteria, pathogenic bacteria, invade the body and begin to reproduce and crowd out healthy bacteria or develop in tissues that are normally sterile. Example: Pneumonia, Tuberculosis (TB).

Disease caused by Protozoa :
Protozoa are single-celled organisms known as eukaryotic. Protozoa can be found everywhere. They will survive on their own as free-living organisms in the environment, sometimes in dirt, water, or mud. They may also be resting cysts, which allow them to live through dry seasons. Infections caused by protozoa can be spread through the ingestion of cysts (the dormant stage of life), sexual transmission, or through insect vectors. Example :Malaria, Diarrhoea.

Note: A healthy diet will provide the body with the required nutrients and help prevent a lot of diseases. Sleeping for 7-8 hours frequently increases the immunity and protects from being sick. Research shows that if we miss a decent night's sleep, then the body is more vulnerable to illness.
