Nigeria restricts access for travellers from India, Brazil and Turkey. Nigeria will restrict access to its territory to all foreign travellers who have stayed in Brazil, India and Turkey over the past two weeks, in order to limit the spread of the coronavirus, health authorities announced Sunday. The travel restriction will take effect from May 4. Sunday's statement -- issued by Boss Mustapha, chairman of the pandemic presidential steering committee, comes in light of the urgent spike in COVID-19 cases and the believed even more contagious virus variants in the concerned countries. This measure does not apply to passengers having made a transit stop by one of these countries. The anti-COVID 19 committee said it made the decision based on a "risk assessment taking into account epidemiology, the prevalence of variants of concern and average passenger volume between Nigeria and each country, among other indicators".
