In the United Kingdom, the Leicestershire County Council has announced that it will be sending parents information about tuberculosis (TB) after more than 20 cases of the disease were discovered at a Leicester school. According to health officials, 22 children and a teacher at Crown Hills Community College have been diagnosed with the disease, together with three of the infected children's relatives; another 60 students may be infected. The British government recently stated that it would once again start immunizing children against TB, starting in September 2001. The immunization program was stopped in 1999, after manufacturing problems led to a shortage of the Bacillus Calmette-Guerin vaccine.
