Whoopee! Cases of Whooping Cough Dropping

Following a record 1,144 cases of whooping cough in 2010, the number of reports of the illness has dropped by 50 percent in Southern California, reports CBS. And last week, no new cases were reported in San Diego County for the first time in eight months.

Despite the encouraging news, it's still too early to say what will happen going forward, says CBS:

Health officials caution that while the data is encouraging, it may be too early to determine whether the epidemic is over.
