Wuhan pneumonia outbreak spurs fever

Published

 on

HONG KONG (BLOOMBERG) – A mysterious pneumonia outbreak that has sickened dozens of people in China has prompted airports in Singapore, Hong Kong and Taiwan to introduce fever screening, as scientists search for the infectious source.

From Friday (Jan 3) evening, temperature screening will be implemented at Changi Airport for all travellers arriving from the central Chinese city of Wuhan, Singapore’s Ministry of Health said.

In Hong Kong, thermal imaging systems will be deployed as part of increased fever surveillance at boundary checkpoints, authorities said.

Taiwan has implemented similar measures, its Centre for Disease Control said Tuesday.

Several clinics and hospitals in Wuhan, the capital of Hubei province, received patients suffering from pneumonia, officials announced on New Year’s Eve.

Twenty-seven people associated with a fresh seafood and produce market fell ill with symptoms, including fever and shortness of breath. Seven were in serious condition and the others were in stable condition, officials in Hong Kong said on Thursday.

The market, which has since been closed, sold birds, pheasants, and snakes, along with organs of rabbits and other wildlife, the Centre for Infectious Disease Research and Policy in Minneapolis said on Thursday, citing local media reports.

That has triggered worries about the potential jump of an unknown virus to humans – reminiscent of Severe Acute Respiratory Syndrome, or Sars, which killed almost 800 people about 17 years ago.

The World Health Organisation said it has activated an incident management team over the Wuhan cases to “ensure disease detection systems are sensitive, communication channels are open, and reporting is rapid across the region,” the South China Morning Post reported.

Investigations are still under way and authorities haven’t yet confirmed the pathogen that is causing the illness, Ms Paige Snider, a WHO spokeswoman, told the paper.

The Wuhan Institute of Virology didn’t respond to an e-mailed request for comment on the infectious source.

FAKE NEWS

Several people were arrested for circulating fake news online about the viral spread of pneumonia, provincial authorities said, adding that rumours on social media alleging that there had been an outbreak of Sars are untrue and no person-to-person transmission has been found so far.

Three travellers from Wuhan were admitted to hospitals in Hong Kong, though two were subsequently released, the South China Morning Post reported late Thursday. The city has not received any Wuhan-related severe pneumonia cases, Secretary for Food and Health Sophia Chan told reporters on Thursday.

Singapore asked doctors to look out for suspected cases of pneumonia among people who have recently returned from Wuhan.

“Suspect cases with fever and acute respiratory illness or pneumonia and with travel history to Wuhan within 14 days before onset of symptoms will be isolated as a precautionary measure to prevent transmission,” the city-state’s Ministry of Health said in a Facebook post.

Interior Health delivers nearly 800K immunization doses in 2023

Published

 on

Interior Health says it delivered nearly 800,000 immunization doses last year — a number almost equal to the region’s population.

The released figure of 784,980 comes during National Immunization Awareness Week, which runs April 22-30.

The health care organization, which serves a large area of around 820,000,  says it’s using the occasion to boost vaccine rates even though there may be post-pandemic vaccine fatigue.

“This is a very important initiative because it ensures that communicable diseases stay away from a region,” said Dr. Silvina Mema of Interior Health.

However, not all those doses were for COVID; the tally includes childhood immunizations plus immunizations for adults.

But IHA said immunizations are down from the height of the pandemic, when COVID vaccines were rolled out, though it seems to be on par with previous pre-pandemic years.

Interior Health says it’d like to see the overall immunization rate rise.

“Certainly there are some folks who have decided a vaccine is not for them. And they have their reasons,” said Jonathan Spence, manager of communicable disease prevention and control at Interior Health.

“I think there’s a lot of people who are hesitant, but that’s just simply because they have questions.

“And that’s actually part of what we’re celebrating this week is those public health nurses, those pharmacists, who can answer questions and answer questions with really good information around immunization.”

Mima echoed that sentiment.

“We take immunization very seriously. It’s a science-based program that has saved countless lives across the world and eliminated diseases that were before a threat and now we don’t see them anymore,” she said.

“So immunization is very important.”

Remnants of bird flu virus found in pasteurized milk, FDA says

Published

 on

The U.S. Food and Drug Administration said Tuesday that samples of pasteurized milk had tested positive for remnants of the bird flu virus that has infected dairy cows.

The agency stressed that the material is inactivated and that the findings “do not represent actual virus that may be a risk to consumers.” Officials added that they’re continuing to study the issue.

“To date, we have seen nothing that would change our assessment that the commercial milk supply is safe,” the FDA said in a statement.

The announcement comes nearly a month after an avian influenza virus that has sickened millions of wild and commercial birds in recent years was detected in dairy cows in at least eight states. The Agriculture Department says 33 herds have been affected to date.

FDA officials didn’t indicate how many samples they tested or where they were obtained. The agency has been evaluating milk during processing and from grocery stores, officials said. Results of additional tests are expected in “the next few days to weeks.”

The PCR lab test the FDA used would have detected viral genetic material even after live virus was killed by pasteurization, or heat treatment, said Lee-Ann Jaykus, an emeritus food microbiologist and virologist at North Carolina State University

“There is no evidence to date that this is infectious virus and the FDA is following up on that,” Jaykus said.

Officials with the FDA and the USDA had previously said milk from affected cattle did not enter the commercial supply. Milk from sick animals is supposed to be diverted and destroyed. Federal regulations require milk that enters interstate commerce to be pasteurized.

Because the detection of the bird flu virus known as Type A H5N1 in dairy cattle is new and the situation is evolving, no studies on the effects of pasteurization on the virus have been completed, FDA officials said. But past research shows that pasteurization is “very likely” to inactivate heat-sensitive viruses like H5N1, the agency added.

Matt Herrick, a spokesman for the International Dairy Foods Association, said that time and temperature regulations for pasteurization ensure that the commercial U.S. milk supply is safe. Remnants of the virus “have zero impact on human health,” he wrote in an email.

Scientists confirmed the H5N1 virus in dairy cows in March after weeks of reports that cows in Texas were suffering from a mysterious malady. The cows were lethargic and saw a dramatic reduction in milk production. Although the H5N1 virus is lethal to commercial poultry, most infected cattle seem to recover within two weeks, experts said.

To date, two people in U.S. have been infected with bird flu. A Texas dairy worker who was in close contact with an infected cow recently developed a mild eye infection and has recovered. In 2022, a prison inmate in a work program caught it while killing infected birds at a Colorado poultry farm. His only symptom was fatigue, and he recovered.

Canada Falling Short in Adult Vaccination Rates – VOCM

Published

 on


Canada is about where it should be when it comes to childhood vaccines, but for adult vaccinations it’s a different story.

Dr. Vivien Brown of Immunize Canada says the overall population should have rates of between 80 and 90 per cent for most vaccines, but that is not the case.

She says most children are in that range but not for adult vaccines and ultimately the most at-risk populations are not being reached.

She says the population is under immunized for conditions such as pneumonia, shingles, tetanus, and pertussis.

Brown wants people to talk with their family physician or pharmacist to see if they are up-to-date on vaccines, and to get caught up because many are “killer diseases.”
