Here's how long coronaviruses may linger on contaminated surfaces, according to science – CNN

It is unknown exactly how long the novel coronavirus can linger on contaminated surfaces and objects with the potential of infecting people, but some researchers are finding clues by studying the elusive behaviors of other coronaviruses.

Coronaviruses are a large group of viruses common among animals. In rare cases, they are what scientists call zoonotic, meaning they can be transmitted from animals to humans, according to the US Centers for Disease Control and Prevention.
Officials do not know what animal may have caused the current outbreak of novel coronavirus in Wuhan, China. But previously, studies have suggested that people were infected with the coronavirus MERS, or Middle East Respiratory Syndrome, after coming in contact with camels, and scientists have suspected that civet cats were to blame for SARS, Severe Acute Respiratory Syndrome.
These human coronaviruses, such as SARS and MERS, have been found to persist on inanimate surfaces — including metal, glass or plastic surfaces — for as long as nine days if that surface had not been disinfected, according to research published earlier this month in The Journal of Hospital Infection.

Cleaning with common household products can make a difference, according to the research, which also found that human coronaviruses “can be efficiently inactivated by surface disinfection procedures with 62-71% ethanol, 0.5% hydrogen peroxide or 0.1% sodium hypochlorite” or bleach within one minute.
The new research involved analyzing 22 previously published studies on coronaviruses, which researchers hope can help provide insight into the novel coronavirus.
“Based on the current available data, I would primarily rely on the data from SARS coronavirus, which is the closest relative to the novel coronavirus — with 80% sequence similarity — among the coronaviruses tested. For SARS coronavirus, the range of persistence on surfaces was less than five minutes to nine days,” said Dr. Charles Chiu, an infectious disease professor at the University of California, San Francisco, and director of the USCF-Abbott Viral Diagnostics and Discovery Center, who was not involved in the new study.
“However, it is very difficult to extrapolate these findings to the novel coronavirus due to the different strains, viral titers and environmental conditions that were tested in the various studies and the lack of data on the novel coronavirus itself,” he said. “More research using cultures of the novel coronavirus are needed to establish the duration that it can survive on surfaces.”

The CDC has noted that coronaviruses are thought to spread most often by respiratory droplets, such as droplets in a cough or sneeze, and coronaviruses in general have “poor survivability” on surfaces — but there is still much to learn about the novel coronavirus disease, named COVID-19.
“It may be possible that a person can get COVID-19 by touching a surface or object that has the virus on it and then touching their own mouth, nose, or possibly their eyes, but this is not thought to be the main way the virus spreads,” according to the CDC’s website.
While there are some similarities between other coronaviruses and the novel coronavirus, there are some differences emerging, too.
“It also appears that COVID-19 is not as deadly as other coronaviruses, including SARS and MERS,” Tedros Adhanom Ghebreyesus, director-general of the World Health Organization, said during a media briefing with reporters Monday.
“More than 80% of patients have mild disease and will recover. In about 14% of cases, the virus causes severe diseases including pneumonia and shortness of breath. And about 5% of patients have critical diseases including respiratory failure, septic shock and multiorgan failure,” he said. “In 2% of reported cases, the virus is fatal, and the risk of death increases the older you are. We see relatively few cases among children. More research is needed to understand why.”
While the novel coronavirus fatality rate is lower than for SARS and MERS, it still seems to be comparable to the 1918 Spanish flu pandemic, Neil Ferguson, professor of mathematical biology at Imperial College London, said in January.
“It is a significant concern, globally,” Ferguson said, noting that we don’t yet fully understand the severity.
Ferguson said he believes the fatality rate is likely to be lower because of an “iceberg” of milder cases that have not yet been identified, but he highlights that novel viruses spread much more quickly through a population.
“Remain informed, but do not panic,” Chiu said.
If you do have concerns, “my recommendations would be frequent hand-washing, avoiding contact with people who are sick, follow home quarantine recommendations according to the latest public health agency guidelines if you have recently traveled from China or were in contact with a known or suspected infected patient,” he said.
But overall, “it is still far more likely that you contract influenza rather than this novel coronavirus, meaning that you should get vaccinated for influenza as well.”
According to the CDC, the flu virus can live on some surfaces for as long as 48 hours and potentially infect someone if the surface has not been cleaned and disinfected.

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.
