<s>[INST] Who should be tested for TB? [/INST] People should be tested for TB if:

they have spent time with someone who is known or thought to have infectious TB disease;

they were born in or frequently travel to countries where TB disease is common;

they live or are employed in a large group setting where TB is more common – such as a homeless shelter, prison or nursing home;

they are a health care worker who cares for patients with TB disease;

they are living with HIV; or

they are a child who may have been in contact with someone with TB disease – children, especially those under 5, have a higher risk of developing TB disease once infected and it is therefore very important to test for TB infection in children who may have been in contact with someone with TB disease.
