African countries are scrambling to avert an outbreak of the rapidly spreading coronavirus strain, as health officials warn that the poorest countries are ill-equipped to combat the deadly disease.

Across the continent, governments have stationed nurses at airports to check for feverish passengers and have suspended Chinese entry visas, while ordinary people grow increasingly nervous.

There have been no verified infections in Africa to date, but deep trade links with China and often overstretched healthcare systems are raising concerns about the capacity to respond to an outbreak.

The World Health Organization (WHO) on Thursday declared a global emergency as coronavirus infections spread, after initially downplaying the threat.

“Our greatest concern is the potential for the virus to spread to countries with weaker health systems,” WHO chief Tedros Adhanom Ghebreyesus said.

J. Stephen Morrison, director of the Global Health Policy Center at the Center for Strategic and International Studies in Washington, said the disease risked taking root if it reaches certain African countries.

He warned that such a scenario could usher in a “global pandemic”.

Several poor African states have recently suffered disastrous viral outbreaks -- and they’re keenly aware of the threat.

The Ebola virus raged through Liberia, Sierra Leone and Guinea in 2014-2016, killing about 11,300 people.

Mosoka Fallah, the head of Liberia’s public health institute, told lawmakers this week that the rapid spread of the new coronavirus was “catastrophic”.

“Steps must be taken as early as possible to prevent it from entering here,” he said, adding that the government had ramped up airport checks.

Anciao Fabiao Paulo, an Angolan student, told AFP that “it’s over” if coronavirus reaches his country.

“Our health system is vulnerable and there are no good specialists. With malaria, people are already dropping like flies,” he said.

Coronavirus has killed more than 200 people in China -- where it emerged in the central city of Wuhan -- and infected thousands more.

At Senegal’s Blaise Diagne International Airport, health officials peer into a small thermal camera before the passport check.

“The first sign of these communicable diseases is a fever,” said Barnabe Gning, in charge of sanitary control in the West African country’s airports.

The doctor, who previously helped prevent Ebola from reaching Senegal, said the airport installed the safety system late last week.

It was only able to do so quickly because, by chance, it had held disease-outbreak training in November.

However, Gning cautioned that thermal cameras are not foolproof.

Similar thermal cameras which detect feverish passengers are now going up across African capitals.

These allow people with a high temperature to be identified -- the camera screen shows their body heat -- and then quarantined pending a lab test confirming a coronavirus infection.
