“In July, about seven cases of suspected Lassa fever were reported in Yobe ."
“They were subjected to normal clinical appraisal and three of the seven were looking less of Lassa fever.We have isolated the cases to prevent unnecessary contact."
“Our epidemic response team has also gone to the affected communities to carryout contact-tracing as well as educate the people on how to deal with the situation,” Kawuwa said.
