24 March is World TB Day.
It marks the date when the bacteria that causes tuberculosis was discovered by a German doctor back in 1882. On World TB Day, WHO calls on young people and adolescents to:
And everyone to:

We have a particular interest in how TB impacts children and it is a much bigger problem than people think. Tuberculosis can affect children indirectly as globally it kills around 1.5 million people each year, leaving millions of children orphaned and in increasing poverty because sick adults can’t provide for their families. It’s also a major cause of infertility in women and can increase the likelihood of complications in pregnancy and low-weight births.
One way that children can help is by being aware of how germs spread by coughing. They can make sure that they ‘cover their cough’ and help others do the same – especially young children they are with. We appreciate that the Covid-19 pandemic has taught all of us to be more careful with our coughs!
After a cough or a sneeze, children can make sure that they wash their hands properly – with soap and that they dispose of any cloths or papers used to ‘catch their cough’ safely.

Tuberculosis, or TB, is an infectious disease caused by the bacteria, Mycobacterium tuberculosis, which most commonly affects the lungs. It is spread by people with TB when they cough or sneeze.
In healthy people, infection with Mycobacterium tuberculosis doesn’t make them ill because their body makes enough antibodies quickly enough to stop the bacteria. When a child is weak or has been ill or has another disease like HIV then TB can make them very ill.
‘Musa’s uncle had a cough for a long time and there was blood in his spit. He coughed up TB germs which Musa and his baby sister breathed in. The germs settled in Musa’s lungs. He began to cough, lost weight and became very weak. His baby sister died.’
Children can be immunised against TB. Immunisation is with the BCG vaccine and protects children against TB meningitis. Scientists all over the world are working hard to find better immunisation for all kinds of TB, for all ages and all kinds of people.
