Portugal is extending until May 16 flight restrictions that stop non-essential travel from countries including Brazil with high coronavirus incidence rates, and added India to the list due to the rapid rise in infections there. Travellers from countries where 500 or more cases per 100,000 people have been reported over a 14-day period - which also include South Africa, France and the Netherlands - can only enter Portugal if they have a valid reason, such as for work or healthcare, the government said on Saturday. Arrivals must then quarantine for 14 days. The decision on India means Portugal is joining a growing number of countries imposing such restrictions. Neighbouring Spain also on Saturday said passengers arriving there from India must go into quarantine for 10 days to avoid spreading COVID-19, a government bulletin said. read more Portugal said people from countries where the incidence rate is 150 or more COVID-19 cases per 100,000 inhabitants, such as Spain and Germany, can also travel by plane to the country only for essential reasons. They will have to present proof of a negative COVID-19 test taken within 72 hours of departure for Portugal. Those without a test will have to take one on arrival and wait for the result at the airport. The extension of air travel restrictions came on the same day most of Portugal moved to the final phase of a gradual easing of rules imposed in January to tackle what was then the world"s worst COVID-19 surge. As infections dropped sharply, lockdown restrictions started to be eased in mid March. Schools, restaurants and cafes, shopping malls, museums and other non-essential services have since reopened, but under strict rules to reduce contagion risk. Portugal"s 1,200 km land border with Spain also reopened on Saturday after more than three months of restrictions and border checks.
