Answer:
by the means of air example corona
Answer:
1.Airborne infections spread when bacteria or viruses travel on dust particles or small respiratory droplets that become aerosolized when an infected person sneezes or coughs. Healthy people can inhale the infectious droplets, or the droplets can land on their eyes, nose and mouth.
2) Two air borne diseases.
- Chickenpox is caused by the varicella-zoster virus.
- Measles is a very contagious disease, particularly in crowded conditions.
3) Infectious diseases can be spread through contaminated water. Some of these water-borne diseases are Typhoid, Cholera, Paratyphoid Fever, Dysentery, Jaundice, Amoebiasis and Malaria. Chemicals in the water also have negative effects on our health.
4) HIV (human immunodeficiency virus) is a virus that attacks the body's immune system. If HIV is not treated, it can lead to AIDS (acquired immunodeficiency syndrome). Receiving blood transfusions, blood products, or organ/tissue transplants that are contaminated with HIV. Being bitten by a person with HIV. Contact between broken skin, wounds, or mucous membranes and HIV-infected blood or blood-contaminated body fluids.
5) A vector is an organism that does not cause disease itself but which spreads infection by conveying pathogens from one host to another. Species of mosquito, for example, serve as vectors for the deadly disease Malaria.
They can be 'communicated', and so are also called communicable diseases. Such disease-causing microbes can spread through the air. This occurs through the little droplets thrown out by an infected person who sneezes or coughs.
