When the Kenyan Government announced the country’s first case of COVID-19, clinician Jackson Njoroge was already hard at work. He and his colleagues from the Kenyan Ministry of Health’s Rapid Response Team had already drawn up a list of people who might have come into contact with the first patient. Now they were rushing to find them. His mission was to find another passenger from the flight that had brought Kenya’s case into the country. The World Health Organization (WHO) has already helped train 1,500 Kenyan health workers in various health facilities to prepare for just this situation. With the announcement, the country’s government and WHO Office shifted from a state of readiness to response mode.
