I have TB, what can I do to stop my family from catching it from me?
If you are diagnosed with TB in the lungs or throat you may be contagious until you have been receiving treatment for two to three weeks. Good hygiene, fresh air and sunlight can all help prevent the spread of TB.
Some useful precautions you can take to prevent the spread of TB to your family or friends:
- cover your mouth when coughing or sneezing
- dispose of any used tissues
- open curtains to ensure a good supply of UV light, this helps kill the bacteria
- open windows to let in fresh air, this prevents bacteria from building up
Only return to work, school or college when your TB treatment team advises you are well enough and that your TB is no longer contagious.
