TREATMENT AND PREVENTION




Treatment and Preventive of TB | Vaccines Tuberculosis

General preventive measures can be taken to reduce the spread of TB in public places. Ventilation systems lessen the chance of infection by dispersing the bacteria. Ultraviolet lighting also reduces, but does not eliminate, the threat of infection by killing TB bacteria in confined spaces. Vaccines, such as the bacillus Calmette Guerin (BCG) vaccine, prepared from bacteria that have been weakened, are another preventive measure. The BCG vaccine is most effective in preventing childhood cases of TB. (TREATMENT AND PREVENTION TUBERCULOSIS, Preventive of TB, Vaccines Tuberculosis)

With the advent of effective antibiotics for TB, drug therapy has become the cornerstone of treatment. Single-drug treatment often causes bacterial resistance to drugs. Therefore, all recommended therapies include multiple drugs given for at least 6 months, often for as long as 9 to 12 months. Adjustments to the treatments are made based on susceptibility of the bacterial strain. A combination of antibiotics, including isoniazid, rifampin, streptomycin, pyrazinamide, and ethambutol, is usually prescribed. In 1998, scientists successfully decoded the entire gene sequence, or genome, of the tuberculosis bacteria. This advance is likely to lead to the development of new methods for treatment and prevention of TB. (TREATMENT AND PREVENTION TUBERCULOSIS, Preventive of TB, Vaccines Tuberculosis)
