Winning the early battle
One thing that does seem certain, says Nkengasong, is that many African leaders got it right in the early stages of the fight.
"The leadership on the continent was extraordinary in responding in a coordinated way," he said.
He says the swift action by many African leaders to close down their economies should get significant credit for slowing community spread in the early months.
South Africa led the way by closing its borders to high risk travelers and shutting its schools in mid-March before reaching 100 confirmed cases. A strict lockdown swiftly followed.
Health experts say that these tough decisions, and the long experience dealing with diseases like Ebola and yellow fever, made a significant impact on transmission rates.
But Karamagi and a group of leading African scientists now believe that socio-ecological factors, the complex way that humans and their environment interact, could be playing an important role.
"We are expecting that the rate of transmission in Africa is lower. It could take a longer time to get to people who are susceptible. And the deaths, the severity of the outbreak will be less severe than we have seen in other countries," he said.
