HIV, tuberculosis and malaria are the three major infectious diseases in the world. In sub-Saharan Africa, the damage caused by these infectious diseases is greater. In recent years, immunochromatography using the rapid diagnostic test (RDT) has been widely used in this area. RDT is used for the initial diagnosis in Japan. In sub-Saharan Africa, it can be easily diagnosed, and this has been funded by The Global Fund. However, now, the microscopic diagnosis of tuberculosis is being carried out, and new tests for TB diagnosis are being requested. On the other hand, in Japan, patients with these infectious diseases are fewer. Thus, the diagnosis of infectious diseases by PCR leads to higher accuracy. In conclusion, reasonably identifying patients with highly prevalent infectious diseases in a country is important. It is also important to accurately diagnose low-prevalence infectious diseases in a country.
