President Muhammadu Buhari has thanked millions of Nigerians who have been sending good wishes and praying for his health and well-being in mosques and churches throughout the country, his spokesperson said Tuesday.

The president’s special adviser on media and publicity, Femi Adesina, said in a brief statement that the president was immensely grateful for the prayers, show of love and concern, and said there was “no cause for worry”.

The statement said “President Buhari wishes to reassure Nigerians that there is no cause for worry.”

Mr. Adesina said on Tuesday that “During his normal annual check-up, tests showed he needed a longer period of rest, necessitating the President staying longer than originally planned.”
