Hello. For everyone's safety and to avoid spreading, in western and developed countries they will isolate people with TB until treatment is complete (ie about 4-6 months and confirmed by culture). sputum for tuberculosis is negative). In Vietnam, this is quite difficult, but the longer the quarantine, the better. We still recommend avoiding contact with people with AFB (+) pulmonary TB at least during the attack, i.e. the first 2-3 months of treatment. Your family member has completed treatment for tuberculosis, so drinking beer with you will not have a risk of contracting TB germs.
If you still have questions about "is drinking beer from the same glass as someone who has had tuberculosis at risk of infection? "You can go to the hospitals of Vinmec Health System for more advice.
