JOHANNESBURG (AP) — The normally bustling supermarket in Wuhan was deserted, looking more foreign than ever. Khamis Hassan Bakari walked the aisles and saw just two other shoppers, and fear sank in.

“Everybody is scared. Scared of seeing anyone,” the 39-year-old Tanzanian doctor said, as authorities around the world scramble to contain the new virus that began in the industrial Chinese city of 11 million. “You don’t even want the supermarket to touch the products you buy.”

Bakari spoke with The Associated Press this week from his university housing in Wuhan as China’s astonishing lockdown of more than 50 million people continues. Transport links have been cut. Streets are largely empty. Lunar New Year festivities have fallen flat.

With thousands of foreigners stranded in Wuhan, and with richer countries like the United States and Japan preparing to evacuate some citizens, the PhD student has become a leader for hundreds of African peers with little chance of a similar escape.

“I’m feeling like I’m trapped here,” said one Ethiopian student at Wuhan University of Science and Technology, who gave only his first name, Abel. He, like other students, cited worries that angering Chinese or their country’s authorities could lead to retaliation, like loss of scholarships.

Beijing’s push to expand its influence on the youthful African continent means Africans now make up the second-largest population of foreign students in China, behind those from elsewhere in Asia, according to China’s education ministry. In 2018 African students numbered more than 80,000.

More than 4,000 are estimated to be in Wuhan alone.

None of them expected this. No one knows how long the lockdown will last, or all the ways the virus can spread. The southern African nation of Botswana has openly worried about its students’ supplies of water and food. Kenya’s government has had to defend itself against accusations it was not helping its students.

So Bakari and a small committee of fellow doctors from his East African country regularly send updates on social media about the outbreak to the more than 400 Tanzanian students in Wuhan, as well as hundreds of countrymen elsewhere in China.

“They don’t have a clue what is going on,” Bakari said. And, because the updates are largely in Swahili, the lingua franca of East Africa, many beyond his country can follow them, too.

“Together we are one family,” the association tweeted Tuesday, encouraging fellow Africans to follow precautionary measures.

The concerns are real. Even Africa’s most developed economy, South Africa, has signaled it will not evacuate citizens. On Sunday it told students in China to adhere to university instructions, warning that leaving without permission “can have far-reaching consequences.” Morocco’s King Mohammed VI, however, has ordered his government to repatriate 100 nationals of the north African nation from Wuhan.

Speaking by phone, Bakari sounded remarkably relaxed, even chuckling, as he described life under lockdown.

“For me as a doctor, I know how to cope with the stress,” the specialist in nuclear medicine said. “So we have initiated a way of going through this ordeal.”

To help keep people calm, the Tanzanian committee has recommended this: Exercise at least 20 minutes a day — and don’t spend too much time online. The committee looked into an online video showing an ill Congolese student at a Chinese hospital that quickly led to fears he had the virus.

“But that guy, he actually had kidney stones,” Bakari said. “We don’t have a foreign student here in Wuhan suffering from the virus, we haven’t heard of any case.”

A Ghanaian student said campus authorities at Wuhan University of Science and Technology had warned students against sharing videos, photos or messages about the virus on WeChat, the popular Chinese messaging app, threatening to cut their WiFi connections if they do.

Students were only trying to learn about the situation, said the student, adding that he wants to leave China the moment transport links are restored.

“This is not the time to be adventurous,” Ghana’s ambassador to China, Edward Boateng, has warned. “Let’s not panic in the process.” The African diplomatic corps in Beijing has been exploring options to help students, reaching out to the U.N. migration agency and others.

Another Tanzanian on the grassroots committee, Dr. Hilal Kizwi, described a situation “full of panic” especially for newer African students who don’t yet speak Chinese.

The new virus started out like a flu, he said. Then authorities told him and others doing their residency at a local hospital to be careful and cover their mouths. Patients started dying, and the number of patients soared. Supplies of masks and other items ran low. Finally, students were told to no longer report to work.

“It’s like I’m locked up in a cell,” Kizwi said shortly after his evening prayers. “The only thing I have is to talk to my family: ‘I’m safe, I’m doing fine.’” And he was, until he heard a local doctor had died of the virus. When he ventured outside after the death, he wore two face masks instead of one.

Students have reached out to Tanzania’s embassy about leaving Wuhan and were told authorities were working on it, Kizwi said. “But I don’t expect it.”

There is little to do. Police are constantly monitoring people who are out and about, his countryman Bakari said. Most supermarkets and pharmacies are closed. The one shop at his and Kizwi’s school, Tongji Medical College, quickly sells out every day.

Bakari said the Tanzanian committee has begun collecting phone numbers of international representatives for all universities in Wuhan so students can report on any shortages or which campuses are being especially helpful.

Some students are given thermometers and visited every day for a temperature check, Bakari said. At his school, they are given face masks daily.

“Our university gave us supplies the day before yesterday,” he said, including two boxes of chocolate, cookies, sugar, cooking oil and bottles of water. “Today there’s new information that if we want to go around the city, we have to ask the local community. They have provided us with a phone number and we call them to ask for transport or supplies, if possible.”

He complimented Chinese authorities on their response: “We really appreciate what they’re doing.”

But Bakari said he has no plans to go out again.

With his new stash from his supermarket visit of fruit, vegetables, legumes and milk powder — to help combat protein deficiency now that eating eggs, fish or meat is not an option since the virus jumped from animals to humans — he has settled into his role as an investigator, semi-therapist and amateur media outlet.

This new reality can be tiring. But “actually we don’t sleep these days,” he said.
