Yale researchers reveal Ebola virus spreads in social clusters
By Ziba Kashef
December 16, 2014
An analysis of the ongoing Ebola outbreak reveals that transmission of the virus occurs in social clusters, a finding that has ramifications for case reporting and the public health.

Prior studies of Ebola transmission were based on models that assumed the spread of infection occurred between random pairs of individuals. However, because transmission of the virus happens most often in hospitals, households, and funeral settings, Yale researchers, and an international team of co-authors, investigated the possibility of clustered transmission, or spread between individuals in small social groups.

...

Researchers were also able to estimate that for every Ebola case reported, fewer than one went unreported. This estimate, that up to 70% of cases were not reported, is significantly lower than previous estimates. ?For Sierra Leone, underreporting is lower than some more speculative estimates that ran as high as 250%,? Townsend noted...
