Measles exposure warning issued for four New York counties

A traveler from Europe may have exposed people to measles in Chemung, Genesee, Livingston and Niagara counties, the New York state Department of Health warned Saturday. The traveler, who has a confirmed case of measles, visited multiple sites in upstate New York on April 30, and May 1-2. Anyone who visited the following locations on these dates and times could have been exposed:

  • Old Country Buffet, 821 Country Route 64, Elmira, between 1 and 4 p.m. April 30.
  • Ontario Travel Plaza on the New York state Thruway in Le Roy, between 4 and 6:30 p.m. April 30.
  • Sheraton Niagara Falls, 300 3rd Street, Niagara Falls, from 5:30 p.m. April 30 to 9:30 a.m. on May 2.
  • Niagara Falls Urgent Care, 3117 Military Road. Suite 2, Niagara Falls, between 3 and 6 p.m. May 1.
  • Exit 5 on Interstate 390 in Dansville, from 9:30 a.m. to noon May 2.

The times reflect the period that the infected person was in these areas and a two-hour period after the individual left the area. The virus remains alive in the air and on surfaces for up to two hours.

takyon: Measles outbreaks have been reported in Okinawa, Pennsylvania, and Missouri recently.

    Before the blood tests a lot of other viruses got diagnosed as measels since they cause the same symptoms. Also people used to literally spread measles on purpose and dont do that anymore. Dont you think the influence of those factors should be accounted for?

    It is not impossible that a different maculopapular rash disease can be mistaken for measles, although it isn't easy because measles has a pretty distinct rash presentation. How much error would you like in the numbers because it is still overwhelming even at 50% misdiagnosis. But I'm talking about the difference between 1980 and 2014, well into the realm of when MMR titers have been available and could be used if there was a question, and generally would be on autopsy if there was a question. So no, I don't think the influence of those factors means much.

      It seems to be somewhere between 90 and 99.5%, but no one seems to study this directly using doctors blinded to vaccination status:

      “A likely reason for this is that the case may have been misdiagnosed as a non-specific viral illness. Measles has become relatively uncommon in Singapore with two decades of widespread measles vaccination, and especially after the second dose policy was implemented in 1998. Many primary care doctors may not even see a single case of measles in a year. This makes diagnosis more difficult.”
      http://www.ncbi.nlm.nih.gov/pubmed/17609829 [nih.gov]

      “This was not a blind study, since the investigators knew which children had received measles vaccine. It seems probable that the occurrence of so much ‘measles-like’ illness in the vaccinated children was a reflexion of the difficulty in making a firm diagnosis of measles in the African child at one visit.”
      http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2134550/ [nih.gov]

      “As only approximately 7% of the clinically-diagnosed cases of measles reported locally turned out to be measles by laboratory testing, there is a need for laboratory confirmation of measles to avoid misidentification of cases and improve disease surveillance.(2)”
      http://www.ncbi.nlm.nih.gov/pubmed/17609829 [nih.gov]

      "Indeed, an average of only 100 cases of measles are confirmed annually [32], despite the fact that >20,000 tests are conducted [28], directly suggesting the low predictive value of clinical suspicion alone. "

      Another thing is we see these same "measles outbreak" stories every year at the same time, measles seems to be cycling in the US the same as it ever did. Last I really looked into it was a few years ago now but it shouldn't matter much:
