Frequently Asked Questions

A healthy diet gives your body the right amounts of carbs, proteins, fats, vitamins, minerals, and water so that it can work properly. It keeps energy, growth, and disease resistance up and stops deficiencies.

Pathogens (like TB and malaria) spread from person to person, while non-communicable diseases (like diabetes and cancer) do not. The first is caused by germs, and the second is caused by genetics or lifestyle, but it doesn't spread.

Vaccines have microbes that are weak or dead that teach the immune system to make antibodies without making people sick. The body remembers the pathogen so it can respond quickly when it gets sick.

Vectors are animals like mosquitoes, flies, and ticks that carry germs from sick people to healthy people. They carry diseases like malaria and dengue without getting sick themselves.

Roughage makes stool bigger, stops constipation, and helps food move through the digestive system. You can find it in fruits, vegetables, and whole grains. It doesn't give you calories, but it's good for your gut health.
