Tanzanian Health Authorities on High Alert to Stop Coronavirus Charles Kombe DAR ES SALAAM, TANZANIA - Dar es Salaam'sKariakooMarket is the biggest in Tanzania and depends on manufactured products imported from China.But the outbreak of the COVID-19diseasehas dried up shipments from China. KhalfanHawadi, a mobile phone trader, said the coronavirus has led to problems with keeping stock up to date. When a trader needs acertain type of phone,he said, it can't be obtained on time -- and meanwhile, the price rises. Those close trade ties with China make Tanzania one of the African countries most at risk of importing COVID-19. Health authorities are on high alert. The assistant director of epidemiology at the Ministry of Health, Dr. JanethMgamba, said officials hadtaken all precautions. A key thing that's been done, he said, "is to strengthen the port of entry because, as you know now, our threat is now coming from the 58 infected countries, including China. We have employed more staff in the port of entry, and we have built their capacity to be able to detect the cases." Tanzania's Health Ministry said140 thermal scanners hadbeen set up in all ports of entry. GeorgeNdaki,a health officer with Tanzania Airports Authority,said some suspected cases had been detected, which showed the machines were working properly. He also said thatin additionto the scanning equipment, ambulances have been standing byto take patients to hospitals. Mobile lab In Tanzania's more remote areas, such as the tourist city of Arusha, the East African Community's Mobile Lab project helps testforsuspected coronavirus infections. Dr. MunaAffara,a laboratory diagnostic coordinator, said that "ifthe outbreak occurs in remote areas, where there may not be diagnostic capacity, the idea is that the mobile laboratory can move quickly and set themselves up in these remote areas and then start diagnosing cases." Meanwhile, Tanzanian doctors such as KelvinKaziriare urging everyone to take precautions to avoid the virus. Kazirisaidthe biggest partof the precautionsinvolves personal hygiene--washing hands with soap, avoiding physical contact with others and covering the mouth when coughing. But at the busy market in Dar es Salaam, avoiding physical contact is a challenge for traders likeHawadi. Even though the coronavirus is a threat to traders'health, without regular shipments of Chinese products, it's a bigger threat to their livelihoods. .
