12. Health risks and tuberculosis

 

The above picture depicts certain health risks which may harm or affect the health in various scenarios.

 

1.  When a person does not use toilets, the flies and mosquitoes sit on the faeces. These flies then again sit on the food that is consumed by humans and cause diseases.

2.  When the hands are not washed properly after touching the faeces, and the same hands are used for cooking and consuming food, it causes diseases.

3.  Usage of unsafe drinking water that is contaminated with faeces also causes diseases.

Communicable diseases such as tuberculosis, cholera, and typhoid are caused by microbes (bacteria) that spread through the air, water, and certain other organisms.

 

  

  

TB is a disease that is caused by the bacteria Mycobacterium tuberculae, a rod-shaped bacteria.

  

 

  

It transmits from person to person through air by spitting and prolonged contact with the materials that are shared with the patient.

 

 

Fever, weight loss, chronic cough, bloody spitting, and difficulty in breathing are some of the symptoms.
