article imageWHO reveals high risk TB countries

By Tim Sandle     Dec 17, 2014 in Health
The estimated rate of tuberculosis (TB) per 100,000 people, compiled from World Health Organisation (WHO) data for each country (2013), shows a rise. There are some interesting geographical findings.
How the WHO data is interpreted varies with different countries. In the U.K., the interpretation is set by the National Institute for Health and Clinical Excellence (NICE). Here countries/territories with an estimated tuberculosis incidence rate of 40 per 100,000 or greater are considered to have a high incidence of tuberculosis.
The report is titled "Global tuberculosis report 2014," and it is the 19th report issued by the health body on this particular disease.
The top ten countries that fall into this category are:
1. Swaziland – 1382 cases per 100,000 people
2. Lesotho – 916 cases
3. South Africa – 860 cases
4. Namibia – 651 cases
5. Djibouti – 619 cases
6. Mozambique – 552 cases
7. Zimbabwe – 532 cases
8. Timor-Leste – 498 cases
9. Kiribati – 497 cases
10. Democratic People's Republic of Korea – 429 cases
With the above, these are, WHO indicates, 'best estimate' figures of incidence.
Tuberculosis (TB) is an infection caused by a bacterium belonging to the Mycobacterium tuberculosis complex. TB usually the lungs but can also affect almost any other area of the body. Most transmissions occur from some people with pulmonary or laryngeal TB are infectious.
As Pharmaceutical Microbiology points out, tuberculosis is only transmitted by people, and the organism cannot survive in the environment. It thrives, however, in the crowded conditions of prisons, refugee camps and slums. Globally, tuberculosis is the second most common cause of death from infectious disease (after those due to HIV/AIDS).
In related news, scienitsts have modified the precursor to one of the drugs used to treat tuberculosis. This is seen as an important first step toward new drugs that can transcend antibiotic resistance issues and treat serious global diseases.
