Hanoi, Muharram 9, 1436, Nov 2, 2014, SPA -- A patient with fever immigrating into Vietnam from Ebola-hit Guinea has been tested to show that he is negative with the deadly virus, medical authorities said on Sunday. Chu Van Chung was hospitalized in the general hospital of Da Nang, central Vietnam, with symptoms of high fever on Saturday, only five days after he returned from Guinea, Xinhua reported. The Department of Health of Da Nang, some 760 km south of Hanoi, announced Sunday afternoon that tests on the 26-year-old patient showed that he is free from the Ebola virus. Chung was isolated at once while his blood and exudates were tested in the National Institute of Hygiene and Epidemiology for Ebola virus. The results showed that Chung was infected with malaria parasites and negative with Ebola virus. Chung was then diagnosed with malaria due to parasite Plasmodium Falciparum and received treatment for severe malaria, said health department said on its website. As of Sunday afternoon, the patient was well responding to the treatment regimen with temperature dropping to 38 degree Celsius with no other special symptoms, according to the health department. In a related development, head of the department Pham Hung Chien said on Sunday afternoon "Blood pressure and other indexes of the patient are stable while he continues to be closely monitored." --SPA 16:50 LOCAL TIME 13:50 GMT www.spa.gov.sa/w
