Article Synopsis
  • Understanding SARS-CoV-2 infection in vulnerable populations, like those in Kakuma Refugee Camp in Kenya, is essential for controlling the disease.
  • From March 2020 to December 2021, data showed that out of 18,864 tests, there were 1,024 positive cases among refugees and the host community, with calculated attack rates and case fatality ratios (CFR) for both groups.
  • While refugees had a lower attack rate of 325.0/100,000 but a higher CFR of 2.9% compared to the host community, this highlights the urgent need for targeted COVID-19 prevention strategies, especially vaccination efforts.
