Ghanaian health authorities have warned against non-essential travel to Covid-19 hotspot countries.
Those planning to travel to countries with high infection rates have been urged to postpone or cancel their trips.
The government mentioned Asia and South America as some of the regions with “alarming rates of infections”.
Health officials at the Kotoka International Airport had noted an increase in travellers testing positive for Covid-19.
The authorities want people arriving from countries with increased coronavirus cases to present themselves for another test three days after arriving.
Ghana has been campaigning for mass vaccination and held a vaccination week during which thousands received the jab.
