Tuberculosis (TB) is a bacterial infection spread by inhaling tiny droplets from the coughs or sneezes of an infected person. Typical symptoms include a persistent cough - sometimes with phlegm that is bloody, weight loss, night sweats, high temperature (fever), tiredness and fatigue, loss of appetite and swellings. An antibiotic called isoniazid (INH) is often prescribed to help prevent the dormant infection from becoming active. If you have active TB disease, your doctor will give you several antibiotics to treat the infection.
