Costco, Masonville mall, Walmart: Health unit releases latest list of measles exposures
As always, public health doctors were tight-lipped about the individual cases, citing privacy concerns, but said most of the cases are related to a larger, unvaccinated cluster linked to a broader outbreak in southwestern Ontario, according to Dr. Joanne Kearon, the associate medical officer of health for the Middlesex-London Health Unit.
All but one of the 16 people were not vaccinated against the disease, she added, and the majority of cases are in kids between the ages of five and nine. The youngest person to get measles is six months old, and the oldest is 35 years old, Kearon said.
The more significant outbreak has been linked to a large gathering of Mennonites in New Brunswick in the fall, the province's chief medical officer of health has said.
"Cases could spread in any unvaccinated community or population but are disproportionately affecting some Mennonite, Amish, and other Anabaptist communities due to a combination of under-immunization and exposure to measles in certain areas," Dr. Kieran Moore wrote to public health officials across the province earlier this month.
Elgin, Oxford, and Norfolk counties have large populations of Mennonite and Amish communities. The outbreaks have forced the London Health Sciences Centre to tighten its visitor rules, and Southwestern Public Health officials are offering vaccines to infants that normally wouldn't be eligible.
Here in Middlsex-London, the cases that aren't linked to the broader outbreak are related to international travel, or the origin isn't known, Kearon said.
The measles virus can live in the air for up to two hours once an infected person leaves an area and can infect nine out of 10 unvaccinated people. People are asked to monitor themselves for symptoms of the illness for up to 21 days from the date of exposure.
The health unit released the following list of places visited by infected people in the previous week:
March 20 - Costco on Wonderland Road North, from 1 p.m. to 4 p.m.
March 20 - Walmart on Fanshawe Park Road West from 2:15 p.m. to 5 p.m.
March 22 - Masonville Place from 2 p.m. to 6:30 p.m.
March 22 - St. Michael's Parish from 5 p.m. to 8 p.m.
March 23 - St. Joseph's Urgent Care from 10 a.m. to 2 p.m.
March 23 - Victoria Hospital adult ER from 1:20 p.m. to 3:45 p.m.
"We are intending to use that exposure list as a way to communicate to the public all of the potential places that the public may have been exposed to measles," Kearon said. "The most important thing that people can do to protect themselves is to get vaccinated."
The Middlsex-London region has a 95 per cent vaccination rate for those over 17 years old, so the overall risk is low, she added.
"Measles vaccine with one dose is 90 per cent effective and with two doses it's 97 per cent effective," Kearon said.
The health unit previously released the following list of places where people may have been exposed to measles:
March 14 - Tiger Jacks on Wharncliffe Road South from 3:20 p.m. to 6:30 p.m.
March 14 to March 15 - Jack's on Richmond Street from 9:30 p.m. to 4:10 a.m.
March 15 - Burrito Boyz on Central Ave from 2:15 a.m. to 4:30 a.m.
March 15 - St. Michael's Parish from 5 p.m. to 8 p.m.
March 16 - Binge Bins on Wonderland Road South from 9:45 a.m. to 4 p.m.
March 16 - Argle Mall Walmart from 3 p.m. to 6 p.m.
March 16 Carter's Osh Kosh at 1925 Dundas St. from 4 p.m. to 7 p.m.

Create Account Data released by Public Health Ontario shows no additional illnesses in the area covered by Southwestern Public Health, which in April accounted for 45% of the province's cases and the highest count in Canada. The benchmark comes after the region reported just one new case for each of the previous three weeks, although there are nine new cases in the neighbouring health unit of Middlesex-London. Public Health Ontario says they are among 22 new cases over the past week, including four reported by the Grand Erie health unit, eight in the summer destination of Huron Perth and one in Chatham-Kent. Southwestern Public Health said earlier this week it was ending local weekly measles reports but stressed that the outbreak was not over.

Read More The province's weekly case additions have hovered around the 20s and 30s lately, with 32 additions logged last week, 21 the week before that, and 11 on July 3. The latest data brings the province's total number of infections to 2,298 since an outbreak began in October. Meanwhile, the Alberta Medical Association is hoping to draw more attention to its outbreak, which logged 1,511 cases as of Thursday. An expert AMA panel called the province's measles situation an epidemic on Wednesday. 'We're probably just seeing the tip of the iceberg,' Dr. Lynora Saxinger, an infectious diseases specialist with the University of Alberta, said on the panel. This advertisement has not loaded yet, but your article continues below. Dr. James Talbot, former chief medical officer of health in Alberta, said describing the spread as an epidemic would appropriately raise the level of urgency for parents to get their kids vaccinated before school resumes. Talbot urged the government to make measles vaccines available to infants as young as six months old in Edmonton and Calgary. The province offers early shots to infants in the hardest hit south, central and north zones. The Alberta government said more than 82,000 measles vaccines were administered across Alberta between March 16 and July 12, representing an increase of more than 55% compared to the same time last year. Nova Scotia reported 30 cases of measles in the northern zone Thursday, up from the single case reported July 7. Health officials say they believe the cases stemmed from travel within Canada to regions where measles is circulating. Manitoba said there were 12 new cases in its weekly report Wednesday, bringing its total number of confirmed infections to 158. Sports Canada Editorials World Toronto & GTA

Colorado's measles outbreak is over, and the weekly US case count continues to diminish
Health officials in Colorado say the state's measles outbreak is over, and the U.S. added just 10 confirmed cases nationally in the last week. Wednesday's national case count stood at 1,319, according to the U.S. Centers for Disease Control and Prevention. Earlier this month, the U.S. passed the total count for 2019, when the country almost lost its status of having eliminated measles. A vast majority of this year's cases are from Texas, where a major outbreak raged through the late winter and spring. Other states with active outbreaks — which the CDC defines as three or more related cases — include Arizona, Georgia, Iowa, Kansas, Kentucky, Michigan, Missouri, Montana, New Mexico, Oklahoma and Utah. There have been three deaths in the U.S. this year, and all were unvaccinated: two elementary school-aged children in West Texas and an adult in New Mexico. North America has three other large outbreaks. The longest, in Ontario, Canada, has resulted in 2,276 cases from mid-October through July 15. The province logged its first death June 5 in a baby who got congenital measles but also had other preexisting conditions. Another outbreak in Alberta, Canada, has sickened 1,472 as of Tuesday. And the Mexican state of Chihuahua had 3,296 measles cases and 10 deaths as of Tuesday, according to data from the state health ministry. Measles is caused by a highly contagious virus that's airborne and spreads easily when an infected person breathes, sneezes or coughs. It is preventable through vaccines and has been considered eliminated from the U.S. since 2000. How many measles cases are there in Texas? Texas did not add any cases in the last week, coming in at 762 measles cases Tuesday across 36 counties, most of them in West Texas. Throughout the outbreak, 99 people have been hospitalized. State health officials estimated less than 1% of cases — fewer than 10 — were actively infectious as of Tuesday. Statewide, only Lamar County has ongoing measles transmission, officials said. In total, though, more than half of Texas' cases (414) have been in Gaines County, where the virus started spreading in a close-knit, undervaccinated Mennonite community. The April 3 death in Texas was an 8-year-old child, according to Health Secretary Robert F. Kennedy Jr. Local health officials said the child did not have underlying health conditions and died of 'what the child's doctor described as measles pulmonary failure.' A unvaccinated child with no underlying conditions died of measles in Texas in late February; Kennedy said the child was 6. How many measles cases are there in New Mexico? New Mexico also stayed steady at 95 measles cases on Tuesday. Lea County has seen the most with 67, but Lea and six other counties no longer have active measles spread, officials said Tuesday. An outbreak of 14 cases tied to a jail in Luna County remains active. An unvaccinated adult died of measles-related illness March 6. The person did not seek medical care. Seven people have been hospitalized since the state's outbreak started. How many cases are there in Oklahoma? Oklahoma held steady a third week at 17 confirmed and three probable cases. The state health department is not releasing which counties have cases, but no counties have recent public exposures. How many cases are there in Arizona? Arizona has four cases in Navajo County. They are linked to a single source, the county health department said June 9. All four were unvaccinated and had a history of recent international travel. How many cases are there in Georgia? Georgia has an outbreak of three cases in metro Atlanta, with the most recent infection confirmed June 18. The state has confirmed six total cases in 2025. The remaining three are part of an unrelated outbreak from January. How many cases are there in Iowa? Iowa announced another measles case on Tuesday, bringing the state's total to eight in 2025. The state health department said the new case isn't linked to others in the state, and occurred in a person who was fully vaccinated. An outbreak in eastern Johnson County involves four cases in members of the same household. How many cases are there in Kansas? Kansas was steady this week with 90 cases across 11 counties in the southwestern part of the state, with eight hospitalizations. All but three of the cases are connected, and most are in Gray County. How many measles cases are there in Kentucky? Kentucky has 13 cases this year. Central Kentucky's outbreak rose to nine cases as of July 8. The cases are in Fayette County, which includes Lexington, and neighboring Woodford County. How many cases are there in Michigan? The state has had 18 cases total in 2025; eight are linked to outbreaks. In northern Michigan, Grand Traverse County has an outbreak of four cases as of Wednesday. An earlier outbreak of four cases in Montcalm County was declared over on June 2. How many cases are there in Missouri? Missouri stayed steady with seven cases as of Wednesday. Five cases are in southwestern Cedar County, and four of those are members of the same family. The fifth case is still under investigation, according to county health director Victoria Barker. How many cases are there in Montana? Montana added two measles cases this week for a total of 27. Cascade County confirmed its first case. Seventeen were in Gallatin County, which is where the first cases showed up — Montana's first in 35 years. Flathead County has two cases, Yellowstone County had three and Hill County had four cases. There are outbreaks in neighboring North Dakota and the Canadian provinces of Alberta, British Columbia and Saskatchewan. How many cases are there in Utah? Utah's measles case count rose by one to 11 as of Tuesday. At least three of the cases are linked, the state health department said last week. State epidemiologist Dr. Leisha Nolen has said there are at least three different measles clusters in the state. Where else is measles showing up in the U.S.? Measles cases also have been reported this year in Alaska, Arkansas, California, District of Columbia, Florida, Hawaii, Louisiana, Maryland, Minnesota, Nebraska, New Jersey, New York, North Carolina, Oregon, Rhode Island, South Carolina, South Dakota, Vermont, Virginia, Washington and Wyoming. Earlier outbreaks in Illinois, Indiana, North Dakota, Ohio, Pennsylvania and Tennessee are over. Cases and outbreaks in the U.S. are frequently traced to someone who caught the disease abroad. The CDC said in May that more than twice as many measles have come from outside of the U.S. compared to May of last year. Most of those are in unvaccinated Americans returning home. What do you need to know about the MMR vaccine? The best way to avoid measles is to get the measles, mumps and rubella vaccine. The first shot is recommended for children between 12 and 15 months old and the second between 4 and 6 years old. Getting another MMR shot as an adult is harmless if there are concerns about waning immunity, the CDC says. People who have documentation of receiving a live measles vaccine in the 1960s don't need to be revaccinated, but people who were immunized before 1968 with an ineffective vaccine made from 'killed' virus should be revaccinated with at least one dose, the agency said. People who have documentation that they had measles are immune and those born before 1957 generally don't need the shots because so many children got measles back then that they have 'presumptive immunity.' Measles has a harder time spreading through communities with high vaccination rates — above 95% — due to 'herd immunity.' But childhood vaccination rates have declined nationwide since the pandemic and more parents are claiming religious or personal conscience waivers to exempt their kids from required shots. What are the symptoms of measles? Measles first infects the respiratory tract, then spreads throughout the body, causing a high fever, runny nose, cough, red, watery eyes and a rash. The rash generally appears three to five days after the first symptoms, beginning as flat red spots on the face and then spreading downward to the neck, trunk, arms, legs and feet. When the rash appears, the fever may spike over 104 degrees Fahrenheit, according to the CDC. Most kids will recover from measles, but infection can lead to dangerous complications such as pneumonia, blindness, brain swelling and death. How can you treat measles? There's no specific treatment for measles, so doctors generally try to alleviate symptoms, prevent complications and keep patients comfortable. ___ The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute's Science and Educational Media Group and the Robert Wood Johnson Foundation.

Create Account Southwestern Public Health announced the change Tuesday, adding that doesn't mean the outbreak is over. It encouraged residents to check for weekly updates on the region from Public Health Ontario, which are released Thursdays. The local health unit began posting weekly reports online in April when communities including St. Thomas, Elgin and Oxford counties accounted for 45% of cases in the province and the most measles infections in Canada. But in its last update Thursday, the public health unit reported just one new case for the third week in a row. Public health experts have expressed cautious optimism about Ontario's overall slowing counts with 32 new cases reported last week.

However, the medical officer of health for Southwestern Public Health says the risk of measles persists, especially for those who are not vaccinated. 'Please continue to be vigilant in preventing measles and protecting yourselves and loved ones through vaccination,' Dr. Ninh Tran said Tuesday in a statement. Public Health Ontario releases weekly reports on measles cases, which are compiled from public health unit data. But as the outbreak surged, the southwestern public health unit also released its own data publicly, with a more localized break down, such as hospitalizations and immunization status of infected individuals within the area. Carolyn Richards, who oversees epidemiologists and public health planners at Southwestern Public Health, said that was done to meet increasing public interest as cases rose. This advertisement has not loaded yet, but your article continues below. 'We had a lot of people on our website and our social media, so we wanted to put out our data in the same place that people were looking for other information,' she said. Richards said her team felt comfortable ending those reports now that spread has slowed, but they could return if cases surge again. 'We don't know that it couldn't increase again. We just know that the cases are low at this time and that it could be possible that's related to summer holidays, kids aren't in school,' Richards said. RECOMMENDED VIDEO Ontario had recorded 2,276 measles cases as of last week. While its case count is still the country's highest, attention has lately turned to Alberta. Alberta reported 47 new cases over the weekend, bringing its total cases since March to 1,454 as of Monday. The province's former chief medical officers of health Dr. Mark Joffe said July 9 that Alberta had twice the rate of confirmed cases than the more populous Ontario. The province of Alberta updates its measles count on weekdays and breaks down the number of cases in each zone, with its south zone accounting for more than half of the cases.
