Most germs are spread through the air in sneezes or coughs. Germs can also spread in sweat, saliva and blood. Some pass from person to person by touching something that is contaminated, like shaking hands with someone who has a cold, then touching your nose. If one of your relatives is sick, cover your mouth and stay away from them if possible. If you're in a closed space, try and open a window to let fresh air in and germs out.
Wash your hands. Remember that germs fear soap and water. Washing your hands often is the best way to beat germs. Keep strong and healthy by eating well, exercising regularly and getting a good night's sleep. This will help you to be prepared to fight germs.
Tuberculosis (TB) is caused by tiny bacteria (germs). The TB bacteria spreads through the air when a person with TB coughs, sneezes, speaks, or sings. People nearby may breathe in these bacteria and become infected. Look out for the following signs: night sweats, feeling weak and tired, an ongoing cough that lasts at least three weeks, blood when you cough, chest pain, a wheezing sound when you breathe, and breathing problems. If you feel strange or think that there's something wrong, don’t wait. Go straight to your closest clinic or hospital.
