To fight the coronavirus, labs are printing its genome – The Verge

Published

 on


Advancements in genetic technology are making it easier, faster, and less expensive for public health experts to understand how the new coronavirus spreads. Time is of the essence for the people on the frontlines of this viral outbreak as the virus has already sickened more than 40,000 people and killed 910.

Researchers got an early win in January. It only took two weeks after public health officials reported the virus to the World Health Organization (WHO) for scientists to isolate the virus and figure out the full sequence of its genetic material. As soon as that sequence was public, biotechnology companies started creating synthetic copies of the virus that could be used in research.

This all happened faster than it ever has before. During the SARS outbreak in 2002, it was months before the viral genome was sequenced and longer still before it was remade in the lab. Speed is important because the outbreak is unlike anything public health experts have seen before. Since the start of February, over 20,000 new people developed confirmed cases of the viral infection. Despite efforts to stop the spread of the virus, some experts worry that it won’t be possible.

Genetic synthesis is also much cheaper than it was two decades ago. Then, it cost $10 to create a synthetic copy of one single nucleotide, the building block of genetic material. Now, it’s under 10 cents. The new coronavirus gene is around 30,000 nucleotides long, so that reduction in price makes a big difference in how many copies scientists can make.

With genetic sequences and synthetic copies, experts were able to quickly develop diagnostic tests for the virus. Last week, just over a month after the virus was reported, the Centers for Disease Control and Prevention (CDC) started shipping testing kits it developed to labs in the US and internationally. It was also able to start creating vaccines. Dozens are under development at pharmaceutical companies, and Anthony Fauci, director of the National Institutes of Allergy and Infectious Diseases, says that one vaccine candidate will enter clinical trials within three months.

In our latest Verge Science video, we take a look at the genetic processes that made these developments possible and how they’re helping in the fight against the coronavirus epidemic.

Correction: An earlier version of this story referred to the coronavirus genetic material as DNA. The coronavirus is an RNA virus.

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

Published

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.
