In China, a major contributor to tuberculosis (TB) infections will be the older population in the next few decades. This will require dedicated efforts to control the disease in the country that can affect million in the country.
The researchers from the London School of Hygiene and Tropical Medicine elucidated the fact that developing a vaccine for “post infection” for TB can control the spread of the diseases by almost one third in the country by 2050.
Worldwide, 2050 is the year to eliminate TB as a public epidemic. China though has advanced considerably to control the disease in the last 20 years, but is still affected hard by the disease.
As per World Health Organization numbers, China has 980,000 cases every year which is only second to India, and has 41,000 deaths each year from the airborne disease. The more concern is that one third of the drug resistance cases are found in China.
China was chosen as the region of study owing to high magnitude of the disease that is present cases and the rising elderly population in the region. The idea of the study was to understand the factors that would affect the elimination of the disease in the country.
It was further elucidated; this is the first type of study in which the impact of giving TB vaccine to the elderly has been considered. The study also finds how future vaccine deployment strategy and clinical trials will be developed.
The earlier studies also suggest that the transmission of TB infection from the elderly could increase from 18% to 53%, and the burden for TB could increase from 13% to 71% for all new cases reported.
