Confirmatory test for TB

If any person has positive TB skin test or QHT - G test then some additional tests should be performed for confirmation of TB infection. These usually include a chest x - ray & test of the phlegm coughed up by the patient. This is done because pulmonary TB is most common & it is highly contagious unlike other forms of TB. If these tests show negative results then one should go for other types of TB. For this purpose blood & urine samples of the patient will be tested. If one has active TB disease then he/she should start taking medicines as directed by the physician. One should also keep in mind that to treat TB one has to take medicine for at least 6 months even if the symptoms are no longer existing (i.e. have to complete the course). Otherwise the TB bacteria will develop resistance against the drugs, as latent asymptomatic form may still exist in the patient’s body if the course of medicine is not followed.

New findings in Malaria

Malaria is one of the most important infectious disease in human history. To eliminate Malaria, countries must treat their entire population, even asymtomatic adults. But there's rarely enough money and medicine for developing nations to do that. So Doctors focus their energies on the young people who are clearly ill. Adults who have developed some level of immunity to malaria end up as reservoirs for parasites, continuing to spread the illness without ever feeling sick.
