COVID in Context: How high-case countries are seeing different kinds of spread
BRYAN, Texas (KBTX) - The World Health Organization is reporting an uptick in cases globally.
However, data suggests that COVID-19 is spreading differently in different countries. For example, in high-case countries like the United States and much of South America, the spread is considered “community transmission,” whereas, in similarly high-case countries like Russia, Spain, and Saudi Arabia, cases are related to “clusters.”
The official Centers for Disease Control and Prevention definitions are as follows:
Clusters of cases: Countries/territories/areas experiencing cases, clustered in time, geographic location and/or by common exposures
- Community transmission: Countries/area/territories experiencing larger outbreaks of local transmission defined through an assessment of
factors including, but not limited to:
- Large numbers of cases not linkable to transmission chains
- Multiple unrelated clusters in several areas of the country/territory/area
