Virus Outbreak Impacts Africans at Home and Abroad Salem Solomon WASHINGTON - African nations are preparing for what experts believe is the inevitable emergence of cases of coronavirus on the continent. With growing economic ties and increased travel between the African continent and China, health professionals say they must be ready to treat and isolate cases. On Tuesday, Ethiopia announced it had quarantined three Ethiopian students and one Chinese student returning from a university in Wuhan, China. The students were stopped during a screening at the airport when it was discovered they had symptoms including sore throat and a cough. Dr. Munir Kassa, chief of staff for Ethiopia's Minister of Health, said the country has been determined to stay ahead of the outbreak. Since the beginning of January, the Ethiopian government has communicated with the World Health Organization and the Chinese government for status updates. "We had several meetings and there is also an emergency center [that] has been activated. And so active surveillance and vigilance. So we have been doing active surveillance of the case for this potential threat," he told VOA's Horn of Africa service. Checking temperatures At Bole International Airport in Addis Ababa, Ethiopia has been using thermal scanners to take temperatures of airline passengers arriving from the affected Chinese region, quarantining anyone sick and taking the addresses of healthy people for follow-up visits. The country has set up quarantine centers and formed a high-level task force that reports to the prime minister. Kassa said they have screened 22,000 passengers and have sent samples from potential coronavirus cases for testing in South Africa. "So currently in our country, we don't have anyone who has contracted this novel coronavirus and those who are suspected are under quarantine. So people can go about their daily business," Kassa said. There is no reason to "be afraid currently." But, he added, "because this is a global issue, particularly in China, and because we have frequent flights, people should take cautions." Other African countries including Kenya, Nigeria and Uganda have begun screening passengers arriving from Wuhan. .
