The National Disaster Risk Reduction Management Council (NDRRMC), raised the code blue alert, activating the national Health Cluster, led by DoH.
Between 1 January to 29 June 2019, including 456 deaths were officially reported through the routine surveillance system from the DOH, with a CFR of 0.43% (see Table 1).
