Wastewater COVID numbers soared in late summer ahead of possible fall wave

Published

 on

WORCESTER, Mass — A temporary rise or the start of something bigger? Epidemiologists can’t predict what’s next for Covid-19. But one indicator suggests the virus may be getting a foothold — one that could mean a wave in the fall.

Biobot Analytics reports the amount of Covid in wastewater rose sharply from July to August — more than doubling nationally, from about 240 copies per milliliter to more than 500 copies. That is still a relatively low number, said Cristin Young, MPH, PhD, an epidemiologist with Biobot — with levels in July five times lower than what Biobot measured the same time last year.

“We were in a pretty high plateau for most of 2022, then it started to decrease to levels that we saw in 2020 and 2021,” said Young.

(For perspective, at the height of the Omicron wave, wastewater concentrations of Covid exceeded 4,000 copies per milliliter.)

While Covid-19 has not proven to be a true seasonal virus, it does seem to follow patterns of infection that pivot on geography and resultant togetherness. In past summers, Covid cases tended to rise in hot parts of the country, as residents of the South and West sought refuge in air conditioned spaces. In Northern states, outbreaks usually hit in fall and winter, as residents escaped the cold.

“I’m not surprised that we’re seeing an increase,” said Young. “It’s summer, people might be spending more time inside, especially with the heat waves we’ve been having.”

Those historic heat waves are likely only part of the reason for Covid’s resurgence. At this point, immunity, for millions, is waning and just as new variants have emerged. The most important of these carry a spike protein mutation known as F456L. One of them, EG5, now accounts for about 20 percent of cases nationally, according to the CDC.

Sandeep Juball, MD, is an infectious disease physician and medical director of the Covid Treatment Center at UMass Memorial Health. He said for much of the summer, he saw a steady trickle of patients.

Now it’s more like a torrent.

“Past, I would say, two or three weeks, there’s been an uptick in the number of treatments we are providing in our center,” Juball said. In fact, the number of patients has risen about six-fold in recent weeks.

“I expect this number to go up,” Juball added.

One wild card in Covid’s deck: an emerging, massively mutated variant known as BA.2.86. So far, five cases have been confined to four countries — the UK, Denmark, Israel and the United States. What concerns researchers about BA.2.86 — also known as BA.X — is that its dozens of mutations are to the spike protein — the very structure targeted by vaccines.

This is a developing story. Check back for updates as more information becomes available.

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.
