Are mosquito-borne diseases becoming more common in Minnesota?


MINNEAPOLIS — Whether you’ve been eaten alive or spared this summer, health officials say don’t let your guard when it comes to mosquitoes just yet.

Minnesota Department of Health epidemiologist supervisor Elizabeth Schiffman says mosquito-borne diseases peak at the end of summer into early fall when there is a larger mosquito population and they’ve had more time to circulate viruses.

“I don’t think it’s something where want people to panic about of course, but definitely knowing that the risk is there and this time of year is definitely the highest risk time,” Schiffman said.

In Minnesota, six mosquito-borne diseases are on the radar of health officials: West Nile virus, La Crosse encephalitis, Jamestown Canyon virus, Western equine encephalitis, Eastern equine encephalitis and St. Louis encephalitis The most common is the West Nile virus.

“We see cases every year, but some years we have a lot of activity and some years not so much,” Schiffman said.

Most who get infected have no symptoms but for some, the West Nile virus can be severe or deadly.

“It’s actually the most serious of the mosquito-borne diseases that we have in the United States,” Schiffman said.

West Nile virus can cause flu-like symptoms and is deadly for about one-third of people who develop it. While EEE has been found in Wisconsin, no human cases have been reported in Minnesota.

“We in Minnesota are in the western edge of the range for that virus, but we have mosquitoes that can spread it. But we just don’t see a lot of activity with it here,” Schiffman said.

Schiffman says a warming climate could mean a longer mosquito season and a greater spread of disease.

“Things are changing and viruses are changing,” she said. “People move so it’s very possible. You know, West Nile virus wasn’t a virus we had in the United States 25 years ago.”

The best way to protect yourself is prevention.

The threat typically diminishes by the end of the month or early October. The first hard frost will get rid of the mosquitoes, too.

5 tornadoes confirmed in Friday’s outbreak in southeastern Minnesota


The National Weather Service confirmed that at least five tornadoes touched down in southeastern Minnesota on Friday, including four that hit Olmsted County. At least another three twisters were confirmed in southwestern Wisconsin.

The NWS was still analyzing data and other information to determine if more tornadoes occurred in the area.

The storms started Friday afternoon, with the first tornado touching down north of Sargeant in Mower County around 1:45 p.m. The short-lived EF0, with top wind speeds of 80 mph, traveled about 3 miles northeast into rural Dodge County near the unincorporated town of Oslo. It lasted for about five minutes in total, the weather service says, and caused minor damage to a grain silo before dissipating.

A new tornado formed a few minutes later, less than a mile away south of Oslo. The storm was also considered an EF0, with wind speeds around 80 mph. Lasting less than 10 minutes, it traveled 4 miles into Olmsted County, causing light damage to farm outbuildings and trees.

The line of storms seemed to pick up intensity as it entered Olmsted County.

Around 2:17 p.m., the EF2 tornado that would later hit Marion Township first touched down just northeast of Stewartville. The weather service estimates that the twister had wind speeds of about 130 mph and traveled nearly 10 miles northeast, before dissipating around 2:31 p.m. Multiple homes were severely damaged with roof removal and partially collapsed exterior walls.

An EF1 tornado was also confirmed to have hit near Potsdam around 2:30 p.m.

The first portion of the tornado was weak, the weather service said, with mainly EF0 damage. On the second portion of the 12-mile track, the tornado intensified to produce approximately 100 mph winds with tree and farm outbuilding damage. It lifted around 2:54 p.m.

A second EF2 tornado was confirmed in Olmsted County around 2:46 p.m. about 5 miles east-northeast of Viola and traveled about 7.5 miles, ending in Wabasha County, a few miles south of Plainview, around 3 p.m. Maximum wind speeds were around 125 mph. The storm affected mainly rural areas and damaged trees and outbuildings. One farmhouse lost a roof and a garage roof, the weather service said.

No injuries were reported in the Minnesota-Wisconsin outbreak.

Friday was a historic day for the NWS La Crosse office, which issued 26 tornado warnings – the most for any one day since the office opened in 1995.

Minneapolis city leaders say law enforcement, community members making Uptown safer, but more must be done

Minneapolis city leaders say law enforcement, community members making Uptown safer, but more must be done


Minneapolis Mayor Jacob Frey, Police Chief Brian O’Hara and other city leaders outlined ongoing efforts to improve safety and livability in the city’s Uptown neighborhood during a news conference Tuesday morning.

The discussion focused on a series of public safety initiatives, including expanded patrols by the Minneapolis Police Department and the planned growth of the city’s Community Safety Ambassador Program in Uptown.

That program is already in place elsewhere in south Minneapolis, on East Lake Street and Franklin Avenue. Officials said Tuesday it will come to Uptown in November. One dispatcher and up to eight ambassadors will be available to perform safety escorts, wellness checks, first aid and more.

Officials say efforts to increase safety in the area have been ongoing since December, when dedicated police patrols were introduced.

“Uptown is experiencing a comeback, but we need to be doing the work to make sure that it happens faster. We’ve all got these beautiful, nostalgic memories about what Uptown was six, seven, eight years ago. Twenty years ago,” Minneapolis Mayor Jacob Frey said. “What’s certain is the Uptown of the future is going to be dramatically different than the Uptown of the past.”

In March, dozens of people lined up for a community meeting discussing safety and livability concerns in the Uptown neighborhood. Data from the city shows there are more assaults, car thefts, robberies and calls for gunshots in the neighborhood compared to the same time last year. Community members, business owners and others have come together to launch community initiatives — like United Uptown — to get the area back on track.

Leaders describe the city’s approach as a coordinated strategy that combines public safety resources, infrastructure investments and partnerships with community organizations. City Council member Elizabeth Shaffer said the goal is “an Uptown that is safe, welcoming and enjoyable for everyone.”

Frey, O’Hara and Shaffer all highlighted drug use as a serious problem in the area. Shaffer and Frey said law enforcement has been helpful in curbing the issue, but more needs to be done. 

“We need to be stepping up to be honest about it, to do something about it, to provide the supports for people who need it and yes, also make sure that we’re enforcing the law,” Frey said. “That’s part of the comeback that we’re going to see in Uptown.”
