Kissore Samad, 12, is sick. He has had a strong fever for 2 days. A surveillance worker who is visiting him is pretty sure that he has malaria as he works 4 hours a day in a forest area around Rourkela in Orissa state, which is one of the Indian states most concerned by malaria. Later in the day, Kissore will attend a clinic where he will be diagnosed with malaria.
