health. Recorded cases of Lyme disease more than doubled in Estrey in 2021 compared to 2020, Esty Public Health revealed. Once again, the RLS in La Pommeraie and Haute-Yamaska ​​had the highest infection rates in the region, with nearly 90% of all infections in the Istrian region.

These two areas totaled 344 cases out of the 387 cases registered in Istria, which is a significant increase compared to the 2020 data, i.e. 157 cases in total in Istria. In the county, 709 cases have been recorded.

In the case of La Pommeraie, which includes most MRC patients in Brome-Missisquoi, the incidence in 2021 was 357.3 per 100,000 population. For Haute-Yamaska, the ratio is 101.3 per 100,000 inhabitants. For comparison, the district rate is 4.0 per 100,000 population.

La Pommeraie and Haute-Yamaska ​​stand out with very high infection rates that are similar to those found in the northeastern United States, according to DPH medical advisor Dr. Genevieve Barron. These two areas of Estri account for 50% of Quebec’s cases. »

However, 2020 saw a decrease in the number of reported cases of Lyme disease compared to the previous year. Just over 200 cases were identified in Istry in 2019.

Public Health indicates that the 2020 cases may have been underestimated due to the effects on the health system and on the consultation habits of the population during the first year of the epidemic.

Bromont is the most likely acquisition spot in the area. Approximately 20.7% of all Istrei cases, and approximately 11.3% of county cases, are associated with the city of Bromont.

It was followed by Granby (12.9% of Estrie cases), Cowansville (8.5%), Lake-Broom (8.3%), Sutton (7.8%), Shefford (7%), Brigham (3.9%), and Denham (3.6%). %) and Frelighsburg (2.8%), all Brome-Missisquoi or Haute-Yamaska ​​municipalities.

Prevent

Dr. Barron took advantage of a public health report on tick-borne diseases to call out key prevention methods to avoid contamination.

» It is recommended to wear mosquito repellent, with either DEET or icaridin, wear long clothing that covers the whole body, if it is not too hot, limit walking in open trails, avoid tall weeds, or graze plants, she said. When you return from an outdoor activity, it is suggested that you take a shower so that you can examine yourself and remove ticks quickly, if you have any. »

She also reminds us that she can get medication to prevent Lyme disease from her doctor or pharmacist. She suggests calling 811 to see if she qualifies.

Lyme disease causes several symptoms, such as localized redness at the site of the bite that can reach 5 cm, fever, chills, or muscle and joint pain.

Public Health also recommends monitoring pets after they have been in the wild. There are animal treatments for Lyme disease.

Dr. Barron also pointed out some tips for controlling ticks in the home by avoiding leaf litter, mowing the lawn regularly, removing weeds and creating clear paths in wooded areas, as well as installing patio spaces and children’s play areas in sunny locations.

Anaplasmosis

An initial group of 35 confirmed or probable cases of anaplasmosis, a disease with symptoms similar to Lyme disease, has also been included in 2021 in the region.

Like Lyme disease, anaplasmosis is also transmitted by tick bites. One of the only occasional differences between the two diseases is the lack of redness typical of Lyme disease.

“In most people, symptoms are mild, but elderly people or people who are immunocompromised can develop more serious illnesses that can lead to hospitalization,” Dr. Barron said.

Half of the anaplasmosis cases were identified among the Bromont population.
