 Nigeria has added South Africa to its red list of countries for arriving passengers. Director-General of the Nigeria Centre for Disease Control, Chikwe Ihekwazu, says the introduction of the restrictions is due to the spread of the Delta variant in South Africa. South Africans join India, Brazil and Turkey on the list. Non-Nigerian passport holders and non-residents who visited the country on the list within 14 days are barred entry from Nigeria while passport holders and residents must undergo a seven-day quarantine in a government-approved facility at a cost to the passenger.
