Coronavirus may be the Disease X WHO cautioned about years ago – Business Standard

Published

The cautioned years ago that a mysterious “disease X” could spark an contagion. The new coronavirus, with its ability to quickly morph from mild to deadly, is emerging as a contender.

From recent reports about the stealthy ways the so-called Covid-19 virus spreads and maims, a picture is emerging of an enigmatic pathogen whose effects are mainly mild, but which occasionally — and unpredictably — turns deadly in the second week. In less than three months, it’s infected about 77,000 people, mostly in China, and killed more than 2,200.

“Whether it will be contained or not, this outbreak is rapidly becoming the first true pandemic challenge that fits the disease X category,” Marion Koopmans, head of viroscience at Erasmus University Medical Center in Rotterdam, and a member of the WHO’s emergency committee, wrote on Wednesday in the journal Cell.

The disease has now spread to more than two dozen countries and territories. Some of those infected caught the virus in their local community and have no known link to China, the US Center for Disease Control and Prevention said.

“We are not seeing community spread here in the United States yet, but it’s very possible — even likely — that it may eventually happen,” Nancy Messonnier, director of the CDC’s National Center for Immunization and Respiratory Diseases, told reporters on Friday.

Unlike SARS, its viral cousin, the Covid-19 virus replicates at high concentrations in the nose and throat akin to the common cold, and appears capable of spreading from those show no, or mild, symptoms. That makes it impossible to control using the fever-checking measures that helped stop SARS 17 years ago.

Spreading surreptitiously

A cluster of cases within a family living in the Chinese city of Anyang is presumed to have begun when a 20-year-old woman carried the virus from Wuhan, the outbreak’s epicentre, on January 10 and spread it while experiencing no illness, researchers said Friday in the Journal of the American Medical Association.

Five relatives subsequently developed fever and respiratory symptoms. Covid-19 is less deadly than SARS, which had a case fatality rate of 9.5 per cent, but appears more contagious. Both viruses attack the respiratory and gastrointestinal tracts, via which they can potentially spread.

While more than 80 per cent of patients are reported to have a mild version of the disease and will recover, about one in seven develops pneumonia, difficulty breathing and other severe symptoms. About 5 per cent of patients have critical illness, including respiratory failure, septic shock and multi-organ failure. “Unlike SARS, Covid-19 infection has a broader spectrum of severity ranging from asymptomatic to mildly symptomatic to severe illness that requires mechanical ventilation,” doctors in Singapore said in a paper in the same medical journal Thursday.

“Clinical progression of the illness appears similar to SARS: patients developed pneumonia around the end of the first week to the beginning of the second week of illness.” Older adults, especially those with chronic conditions, such as hypertension and diabetes, have been found to have a higher risk of severe illness. Still, “the experience to date in Singapore is that patients without significant co-morbid conditions can also develop severe illness,” they said.

COVID-19 immunization clinics open to B.C. kids ages five to 11 today – Toronto Star

Published

 on


VICTORIA – Children in British Columbia between five and 11 years old can start getting shots of a pediatric COVID-19 vaccine today.

Provincial health officer Dr. Bonnie Henry said last week that about 350,000 children are eligible to receive the modified dose of the Health Canada-approved Pfizer-BioNTech vaccine.

Health Canada approved the pediatric shot for use in Canada after an independent scientific review confirmed the first vaccine formulated for younger children is safe and effective.

Henry says the same vaccine has been administered to more than three million children in the United States and there have been no “safety signals” as a result.

She says the vaccine will help children and families safely return to activities that benefit physical and mental health.

Dr. Penny Ballem, the executive lead for B.C.’s vaccination drive, has said she expects the full children’s immunization effort including second doses to conclude by the end of January.

This report by The Canadian Press was first published Nov. 29, 2021.

More than 90,000 out of the 350,000 eligible children, or 26 per cent, in that age category were registered a week before the rollout, according to the B.C. government.

The government’s own surveys show that most parents support getting vaccines for their young children, but there are some whose views might keep the vaccination rate lower for this age category.

Of B.C. parents who responded, 58 per cent will register to vaccinate their children right away, while another 18 per cent planned to wait, and nearly 25 per cent said they are not sure they will do it, according to Penny Ballem, the executive lead for B.C.’s immunization efforts.

A parent or legal guardian has to give verbal consent ahead of a child being vaccinated, according to Ballem.

Health Canada approved the Pfizer vaccine for children aged five to 11 on Nov. 19. This vaccine uses a lower dose of 10 micrograms that is one-third of the dose given to older children and adults.

COVID-19 information from the B.C. Centre for Disease Control from Nov. 25 shows that 80 per cent of British Columbians at the next age group up, aged 12 to 17, are now fully vaccinated and more than 87 per cent have a first dose.

There are varying rates in different health authorities, however. In Fraser, Vancouver Coastal and Vancouver Island, it is higher at 82 per cent, 89 per cent and 83 per cent, respectively. In Interior, it was 70 per cent and in Northern, it was 59 per cent.

Within authorities, there is also a wide spectrum. As of Nov. 23, Enderby and Kettle Creek in the Interior authority had only 38 per cent of 12- to 17-year-olds double vaccinated, while Kimberley posted 80 per cent. In Vancouver Coastal, Bella Coola Valley had 59 per cent of 12- to 17-year-olds double vaccinated, while North Vancouver was at 93 per cent.

Between Oct. 27 to Nov. 25, the number of average daily cases per 100,000 people among the double vaccinated for this 12 to 17 age group across B.C. was 2.5. Among those who had one vaccination, the number of average daily cases per 100,000 people was 8.2. And for the unvaccinated, the figure was 46.8 per 100,000.

For that same period, in the category of 0-11 year olds, who are all unvaccinated, the number of average daily cases per 100,000 people was 16.8.

“I think the most important thing is that vaccinations be readily available for all children and families,” said Teri Mooring, president of the B.C. Teachers’ Federation.

“For families where it’s not convenient for them to book an appointment in a separate clinic or perhaps they work long hours or there are other various individual circumstances, we think there should be an option (for COVID-19 vaccination) in schools as well.”

Mooring said that “it was a concern with the 12- to 17-year-olds as well and what we’re seeing in some parts of the province, where we have vaccine hesitancy, we are still those (vaccination) numbers lag behind. We don’t want that to be the case for the five to 11-year-olds.”

Youth aged 12 to 18 have to carry a B.C. Vaccine card, or have a trusted adult carry one for them, to go to restaurants and attend indoor, organized events. Unlike adults, they don’t have to also show government-issued identification. Children aged five to 11 are not be required to show proof of vaccination.
