The Ministry of Health uses WHO case definitions for suspected cases, confirmed cases and probable cases. It has adapted a case definition for contact cases. Probable cases are defined as having returned from a high-risk country 14 days before the onset of symptoms. Contacts are defined as having had contact with a confirmed case of COVID-19 infection in the country. Contact tracing is being implemented. So far, the Ministry of Health is able to trace all cases to several clusters. The Ministry of Health is using event and indicator-based surveillance.
