c. The American army used a lot of antibiotics to treat syphilis amongst the soldiers, unfortunately this created a stronger drug resistant version of syphilis. Explain in detail how this could happen?

Assignment 4 - I:

7. Despite the World Health Organisation efforts to expand access to the tuberculosis treatment, multidrug resistant tuberculosis (MDR-TB) remains a major threat. MDR-TB represents a challenge for clinicians and staff operating in national tuberculosis (TB) programmes/centres. In sub-Saharan African countries including Burundi, MDR-TB coexists with high burden of other communicable and non-communicable diseases, creating a complex public health situation which is difficult to address. Tackling this will require targeted public health intervention based on evidence which well defines the at-risk population. In this study, using data from two referral anti-tuberculosis in Burundi, we model the key factors associated with MDR-TB in Burundi.

a. What type of pathogen is MDR-TB?

b. Why is MDR-TB more dangerous than regular TB?

c. Some kids in the Netherlands have been vaccinated and others have not, why is there a difference in this policy?
