( CNN ) -- Washington state health officials have issued a warning to anyone who may have been in the vicinity of a particular woman at the end of March : You may have been exposed to measles , a highly contagious and potentially fatal respiratory disease . Privacy laws prevent them from showing you the woman 's picture or telling you her name , so they 're trying another tack : they 're telling you where she 's been . The Department of Health posted where she was virtually every hour of the day between March 26 , when she became contagious , and March 29 , so that you can determine whether you are at risk and possibly need medical attention . `` I 've seen it happen pretty regularly when it comes to significant infectious disease circumstances , '' agency spokesman Tim Church said Tuesday when asked whether this was a unique approach to quelling a public health crisis before it starts . `` What 's unique is the extent of the schedule this person had while ill , '' he told CNN . The 20-something Whatcom County woman did n't seem to be slowed a bit by the infectious disease . She kept a schedule that would be the envy of any healthy bon vivant . On Friday , March 28 , for example , after working from 7 a.m. to 5 p.m. at the at the Lynden Dutch Bakery ( home of the `` world 's best scones '' according to its website '' ) , she made a stop at Lynden Wine and Spirits before checking into the Best Western in downtown Seattle at 7:15 p.m. She then took in the Kings of Leon concert at Key Arena -- about a 20-minute walk from the hotel -- until midnight . She kept the party going at a place called Wasabi Bistro until 3 a.m. before finally heading back to her hotel . The next day was spent traipsing around like an energetic tourist : lunch in Pike Place Market , then south to Tacoma to take in the LeMay car museum and a visit to a place called the Celebrity Cake Studio before bellying up at Harmon Brewing Co. and Eatery in Pierce County . Measles is so highly contagious that you can get it by simply walking into a room where someone with it had been hours before -- which is why her attending the concert is a concern . `` This was n't a local bar , '' Church said . `` It was a major concert at a major venue . '' Even though most people in Washington state are vaccinated -- 96 % statewide by 6th grade -- Key Arena holds 15,000 people for concerts , signifying the potential for exposure , given some concertgoers may have been from out of state . `` It 's a serious illness , '' said Church . `` Measles has a way of finding those who are not vaccinated . '' There have been no linked reported cases thus far , according to Church . `` It 's still early . '' The department says the woman became contagious with measles on March 26 after visiting a local family member with measles linked to an outbreak in British Columbia . Fraser Health , the health authority in British Columbia , confirms 375 cases of measles as of April 8 . Church would not pinpoint when the woman was diagnosed , only that it occurred between March 29 and April 2 , when the agency posted her schedule online . `` Anyone who was in those locations at the listed times should find out if they have been vaccinated for measles or have had measles previously , '' the agency said . Those who are n't and `` develop an illness with fever or unexplained rash should consult a health care professional immediately . '' As for the patient , Church says that she is recovering . CNN 's John Newsome contributed to this report .
