This study sheds new light on understanding COVID-19 response in South Africa, Nigeria, Ghana, Kenya, Zambia, and Zimbabwe by employing social network analysis for Twitter. This study finds that African countries have different social networks for COVID-19. For instance, news media play an important role in South Africa, governmental key players exert a significant impact on Nigeria, and African key players play a significant role in Ghana. The Ministries play a significant role in Kenya, institutes and organizations play a critical role in Zambia, and the Minister of Health and the President of Zimbabwe play an important role in Zimbabwe. Second, African countries show different social network systems according to groups.

Third, African countries have different top-mentioned tweeters in the networks.
