>> now to the resurgence of the measles here in the united states . at least 159 cases have been documented this year with the biggest outbreak tied to a mega church in texas. janet has details on this. good morning to you.
>>> hey, matt, this outbreak is alarming health officials because generally we don't see cases of measles anymore. this concentration is tied to this church . it is led by a celebrity minister and his pastor daughter who have been critical of vaccines in the past.
>> reporter: this sprawling texas mega church near fort worth is the epicenter of the outbreaks. at least 16 cases originated here. 7 adults, 9 children. the youngest, 4 months old. and many home skoochooled. officials say 11 had no vaccines with no medical records of vaccines for the others. dr. karen smith works at the church and spotted the disease most think of as wiped out.
>> this little guy presented to the clinic with textbook symptoms one day and i didn't know enough to know that meeasles should be gone.
>> the outbreak is blamed on a church visitor that travelled overseas and then interacted with other church members.

>> reporter: the cdc reports an alarming spike in the number of cases. 159 so far this year. almost triple the 2012 total of 55.
