After a two-month hiatus, the mysterious coronavirus that killed one man and hospitalized another is back on the scene. This time it has infected members of the same family.
The new cases raise the known total to six, including two deaths.
Scientist are trying to figure out if the involvement of a family says something new about the virus.
It now appears that the new coronavirus found on the Arabian Peninsula is more widespread than initially thought, even though only two people are known to have gotten sick from it.
At first it seemed likely that the two known cases of illness from the new cousin-of-SARS virus may have been exposed in or near the Saudi Arabian city of Jeddah on the Red Sea coast.
