The World health Organization is reporting that human-to-human transmission is likely in the Indonesian cluster of eight infected family members. [See Effect Measure: WHO update on Indonesia cluster: not comforting]
All confirmed cases in the cluster can be directly linked to close and prolonged exposure to a patient during a phase of severe illness. Although human-to-human transmission cannot be ruled out, the search for a possible alternative source of exposure is continuing.
While no cause for alarm now, this is disturbing news. It suggests the virus is mutating to be more compatible with humans.
