Local cases of Lyme disease up substantially from 2020 to 2022

Published

 on

The number of local confirmed cases of Lyme disease has increased substantially since 2020. 

A report on the vector-borne disease program was presented at a Haldimand-Norfolk health and social services advisory committee meeting on Nov. 27.
Vector-borne diseases are human illnesses caused by bacteria, viruses and parasites. These illnesses or infections are transmitted to humans by vectors such as mosquitoes, ticks, flies, sandflies and fleas, with mosquitoes responsible for the majority of the diseases.

The report indicates there were 27 human cases of Lyme disease, transmitted to humans by the bites of deer ticks infected with the Borrelia bacterium, identified within the Haldimand Norfolk Health Unit in 2022, compared to 26 in 2021, but up from seven in 2020.

Last year, the health unit identified, through active tick surveillance, Port Dover and Jarvis as new risk areas for Lyme disease in Haldimand-Norfolk.

Across the province there were 1,455 reported human cases of Lyme disease, down from 1,587 cases the previous year but significantly higher than the 809 cases reported in 2020.

Alexis Atkinson, program manager of the environment health team, said possible reasons for the fluctuation in numbers include more travel to risk areas as pandemic restrictions were lifted and climate change.

“Warmer temperatures are expected to increase the incidence of Lyme disease through increased tick maturation rates and a longer available season of transmission,” said the report.

There continue to be no local confirmed cases of West Nile Virus, typically spread by mosquitoes. The health unit tested eight mosquito traps bi-weekly from June to August last year. Four were set in different locations in Norfolk and another four in Haldimand County. No mosquito pools tested positive and no human cases of West Nile Virus were identified in 2022, 2021 or 2020.

Last year in Ontario, there were 29 reported human cases of the virus, compared to 24 in 2021 and 98 in 2020.

Coun. Chris Van Paassen questioned the need for trapping.

“If we recognize that ticks are endemic to Haldimand-Norfolk and mosquitoes are endemic, why do we waste money trapping them and identifying them,” said Van Paassen. “Shouldn’t more of the resources be put into education?”

Atkinson said surveillance is used to determine trends so education about how people can protect themselves from disease can be targeted to areas with high tick populations.

Dr. Joyce Lock, acting medical officer of health for Haldimand-Norfolk, said determining where ticks are is important to the initial period of assessment for Lyme disease. 

“Testing isn’t helpful in the initial period and assessment is made based on the risk of Lyme disease within a certain geographical area,” said Lock. “That’s why tick dragging is so important. We need to know where the ticks are and where people get bitten because it is a significant contributor to making a clinical decision about whether that person may be at risk for getting Lyme disease from that tick. Testing comes into play later on.

“Usually, these diseases show up six, eight, 12 months or two years after the initial bite. At that time, the test is required and is really reliable.”

Lock said the real risk of Lyme disease begins after a tick has been attached to a person for more than 72 hours, so it’s important people do a check right after they’ve been out in an area known to have a high tick population.

Canada to donate up to 200,000 vaccine doses to combat mpox outbreaks in Africa

Published

 on

 

The Canadian government says it will donate up to 200,000 vaccine doses to fight the mpox outbreak in Congo and other African countries.

It says the donated doses of Imvamune will come from Canada’s existing supply and will not affect the country’s preparedness for mpox cases in this country.

Minister of Health Mark Holland says the donation “will help to protect those in the most affected regions of Africa and will help prevent further spread of the virus.”

Dr. Madhukar Pai, Canada research chair in epidemiology and global health, says although the donation is welcome, it is a very small portion of the estimated 10 million vaccine doses needed to control the outbreak.

Vaccine donations from wealthier countries have only recently started arriving in Africa, almost a month after the World Health Organization declared the mpox outbreak a public health emergency of international concern.

A few days after the declaration in August, Global Affairs Canada announced a contribution of $1 million for mpox surveillance, diagnostic tools, research and community awareness in Africa.

On Thursday, the Africa Centres for Disease Control and Prevention said mpox is still on the rise and that testing rates are “insufficient” across the continent.

Jason Kindrachuk, Canada research chair in emerging viruses at the University of Manitoba, said donating vaccines, in addition to supporting surveillance and diagnostic tests, is “massively important.”

But Kindrachuk, who has worked on the ground in Congo during the epidemic, also said that the international response to the mpox outbreak is “better late than never (but) better never late.”

“It would have been fantastic for us globally to not be in this position by having provided doses a much, much longer time prior than when we are,” he said, noting that the outbreak of clade I mpox in Congo started in early 2023.

Clade II mpox, endemic in regions of West Africa, came to the world’s attention even earlier — in 2022 — as that strain of virus spread to other countries, including Canada.

Two doses are recommended for mpox vaccination, so the donation may only benefit 100,000 people, Pai said.

Pai questioned whether Canada is contributing enough, as the federal government hasn’t said what percentage of its mpox vaccine stockpile it is donating.

“Small donations are simply not going to help end this crisis. We need to show greater solidarity and support,” he said in an email.

“That is the biggest lesson from the COVID-19 pandemic — our collective safety is tied with that of other nations.”

How many Nova Scotians are on the doctor wait-list? Number hit 160,000 in June

Published

 on

 

HALIFAX – The Nova Scotia government says it could be months before it reveals how many people are on the wait-list for a family doctor.

The head of the province’s health authority told reporters Wednesday that the government won’t release updated data until the 160,000 people who were on the wait-list in June are contacted to verify whether they still need primary care.

Karen Oldfield said Nova Scotia Health is working on validating the primary care wait-list data before posting new numbers, and that work may take a matter of months. The most recent public wait-list figures are from June 1, when 160,234 people, or about 16 per cent of the population, were on it.

“It’s going to take time to make 160,000 calls,” Oldfield said. “We are not talking weeks, we are talking months.”

The interim CEO and president of Nova Scotia Health said people on the list are being asked where they live, whether they still need a family doctor, and to give an update on their health.

A spokesperson with the province’s Health Department says the government and its health authority are “working hard” to turn the wait-list registry into a useful tool, adding that the data will be shared once it is validated.

Nova Scotia’s NDP are calling on Premier Tim Houston to immediately release statistics on how many people are looking for a family doctor. On Tuesday, the NDP introduced a bill that would require the health minister to make the number public every month.

“It is unacceptable for the list to be more than three months out of date,” NDP Leader Claudia Chender said Tuesday.

Chender said releasing this data regularly is vital so Nova Scotians can track the government’s progress on its main 2021 campaign promise: fixing health care.

The number of people in need of a family doctor has more than doubled between the 2021 summer election campaign and June 2024. Since September 2021 about 300 doctors have been added to the provincial health system, the Health Department said.

“We’ll know if Tim Houston is keeping his 2021 election promise to fix health care when Nova Scotians are attached to primary care,” Chender said.

Newfoundland and Labrador monitoring rise in whooping cough cases: medical officer

Published

 on

 

ST. JOHN’S, N.L. – Newfoundland and Labrador‘s chief medical officer is monitoring the rise of whooping cough infections across the province as cases of the highly contagious disease continue to grow across Canada.

Dr. Janice Fitzgerald says that so far this year, the province has recorded 230 confirmed cases of the vaccine-preventable respiratory tract infection, also known as pertussis.

Late last month, Quebec reported more than 11,000 cases during the same time period, while Ontario counted 470 cases, well above the five-year average of 98. In Quebec, the majority of patients are between the ages of 10 and 14.

Meanwhile, New Brunswick has declared a whooping cough outbreak across the province. A total of 141 cases were reported by last month, exceeding the five-year average of 34.

The disease can lead to severe complications among vulnerable populations including infants, who are at the highest risk of suffering from complications like pneumonia and seizures. Symptoms may start with a runny nose, mild fever and cough, then progress to severe coughing accompanied by a distinctive “whooping” sound during inhalation.

“The public, especially pregnant people and those in close contact with infants, are encouraged to be aware of symptoms related to pertussis and to ensure vaccinations are up to date,” Newfoundland and Labrador’s Health Department said in a statement.

Whooping cough can be treated with antibiotics, but vaccination is the most effective way to control the spread of the disease. As a result, the province has expanded immunization efforts this school year. While booster doses are already offered in Grade 9, the vaccine is now being offered to Grade 8 students as well.

Public health officials say whooping cough is a cyclical disease that increases every two to five or six years.

Meanwhile, New Brunswick’s acting chief medical officer of health expects the current case count to get worse before tapering off.

A rise in whooping cough cases has also been reported in the United States and elsewhere. The Pan American Health Organization issued an alert in July encouraging countries to ramp up their surveillance and vaccination coverage.
