Tuberculosis and Malaria
Why treating tuberculosis and malaria within the same lesson? After all, they are quite different diseases, one of them being caused by a bacterium and the other one by a parasite (see Sect. 4.1). These pathogens do not attack the same organs. The clinical manifestations and diagnostic methods of the two diseases are not the same. Their dynamics of transmission are not at all alike, tuberculosis being transmitted directly from man to man whereas malaria passes through an intermediate host. As a consequence, preventive measures against tuberculosis and malaria also differ fundamentally. Therefore in Vietnam there exist two separate networks of services, one devoted to tuberculosis and the other one to malaria, each headed by a central institute in Hanoi.
