China locks down city at center of virus outbreak

Published

 on

Authorities in Wuhan, where the virus outbreak began, have closed off the city by suspending public transport. The World Health Organization has delayed a decision on declaring a global public health emergency.

The World Health Organization (WHO) on Wednesday postponed a decision to declare a global public health emergency over a new viral illness that has spread across China and reached other Asian nations as well as the United States.

“The decision about whether or not to declare a public health emergency of international concern is one I take extremely seriously, and one I am only prepared to make with appropriate consideration of all the evidence,” said WHO chief Tedros Adhanom Ghebreyesus.

An emergency meeting of experts will consider further evidence on whether to determine a global public health emergency on Thursday.

City of 11 million cut off

Wuhan authorities have effectively locked down the area, shutting down all public transportation services, including high-speed trains in and out of the city which is home to some 11 million people.

Authorities in China, where the virus originated, said the number of cases of a new virus had jumped to 571 and the death toll had risen to 17 at the end of Wednesday.

‘Further spread’ possible

Deputy Director of the National Health Commission Li Bin told reporters on Wednesday that all the deaths were reported in the city of Wuhan in the central Hubei province.

The new death toll comes less than a day after the first case in the US was reported. A person with the virus was also found in Hong Kong for the first time. Travelers from China are being screened for the virus at many airports around the world. The UK said it would put enhanced monitoring measures in place for direct flights from Wuhan.

The coronavirus is transmitted via the respiratory tract and there “is the possibility of viral mutation and further spread of the disease,” Li said at a news conference. The commission announced measures to contain the virus as millions of people travel across the country for this week’s Lunar New Year holiday, including disinfection and ventilation at airports, train stations and shopping centers.

“We are still in the process of learning more about this disease,” said Gao Fu, an academician of the Chinese Academy of Sciences and head of the Chinese Center for Disease Control, at the press conference.

Is the new virus a ‘super spreader’?

Li said there was so far no evidence that the new virus was a “super spreader” — meaning it infects a disproportionate number of people. However, he said that it still remained a possibility and a research target for the investigation.

“We will step up research efforts to identify the source and transmission of the disease,” Li vowed.

The new coronavirus has caused alarm for its similarity to SARS (Severe Acute Respiratory Syndrome), which also started in China and killed nearly 800 people between 2002 and 2003.

Will the virus spread further?

“At present, during the Lunar New Year, the rise in the mobility of the public has objectively increased the risk of the epidemic spreading and the difficulty of prevention and control,” Li also warned.

In addition to the case reported in the US, the Chinese Special Administrative Region of Macau also recorded its first case of pneumonia caused by the virus on Wednesday. The patient was a tourist from Wuhan.

Casino staff in the gambling hub have duly been ordered to wear masks.

More suspected cases have been identified in Taiwan, the Philippines, Thailand, Japan, South Korea and even Mexico. In Australia, authorities isolated a man in his Brisbane home after he flew back from Wuhan in a suspected coronavirus case. Tests later ruled out an infection.

Meanwhile, Hong Kong’s Cathay Pacific Airlines will allow airline staff to wear surgical masks and will not charge people who cancel or change flights to Wuhan.

No travel to North Korea

Authorities in North Korea, which shares a land border with China, suspended border crossings for all foreign tourists, according to tour operators in China. It was not immediately clear how long the suspension would last.

North Korea has “closed all of their borders until further notice due to coronavirus,” Koryo Tours said in an email cited by the AP news agency.

Pyongyang did not immediately confirm the report.

The isolated, Communist-ruled nation had closed its borders during similar health scares, such as the SARS outbreak in 2003 and the Ebola epidemic in 2014.

New technology to advance women’s cancer care at Southlake

Published

 on

NEWS RELEASE
SOUTHLAKE REGIONAL HEALTH CENTRE
**************************
This Cancer Awareness Month, Southlake is adding advanced technologies to detect and treat breast cancer and other women’s cancers thanks to generous community donor support, most recently through the HERE is Where Cancer Meets its Match campaign. New cancer care technology, including new mammography machines, the MyoSure System and the MOLLI 2® System will make a measurable impact in diagnosing and treating women’s cancers in the communities Southlake serves.

Southlake is installing three new mammography machines to expand its breast cancer screening program to 1,500 more women each year. Two of these machines have new biopsy capabilities that will reduce the number of cancelled exams due to equipment failure, ensuring timely care for women. Women ages 40 to 49 years old will be able to self-refer for publicly funded mammograms through the Ontario Breast Screening Program starting this fall.

“Early detection is critical when treating breast cancer and other women’s cancers,” said Lorrie Reynolds, Director, Regional Cancer Program at Southlake. “We treat more than 1,700 breast cancer patients at Southlake every year. By adding advanced technology, like the new mammography machines, we’re ensuring women have the best experience at Southlake.”

Southlake is also introducing the MyoSure System, an innovative technology that can help detect female reproductive cancers. Damaged tissue in a woman’s uterus such as fibroids and polyps can now be removed in a precise, minimally invasive procedure that leaves the rest of the uterus intact. This will improve the overall patient experience by supporting faster recovery, reducing the risk of infection and giving more women the option to have children. An estimated 200 women per year will benefit from the MyoSure System.

300x250x1

The new mammography machines and the MyoSure System build on Southlake’s recent investment in the MOLLI 2® System, a made-in-Canada wire-free breast localization technology.  This technology is considerably less invasive and more accurate when compared to wire-guided localization, resulting in a better patient experience and improved cosmetic outcomes.  More than 200 women each year will benefit from this innovative medical device as they are treated for breast cancer at Southlake.

“As a clinician caring for women with cancer in our community, I’m incredibly proud of the work Southlake is doing to advance women’s health and improve patient experiences,” said Sara Temple, MD, Surgical Oncologist and Chief of Surgery at Southlake. “Women who visit Southlake can be confident that they are receiving leading edge care, close to home when they need it most.”

The World Health Organization anticipates a 77 per cent increase in cancer diagnoses by 2050.  Southlake serves some of the fastest growing communities in Canada and anticipates that the number of patients requiring cancer care will grow. By investing in new technology, Southlake is ensuring that women in the communities it serves have access to leading edge cancer care. All of these investments were funded with support from community donors who generously gave to Southlake to support investments into women’s health at the hospital.

“The generosity of our donor community and the impact they have made for women receiving cancer diagnosis and treatment at Southlake is something we can all take great pride in,” said Jennifer Ritter, President and CEO of Southlake Foundation. “From our Women’s Health Initiative donors supporting new mammography machines, to the Ladies in Philanthropy for Southlake funding the MOLLI 2 System, to our long-standing partners The Edge Benefits and Pheasant Run Golf Club enabling the introduction of MyoSure System through their joint annual charity golf tournament, we are incredibly lucky to share a vision of access to exceptional care for everyone who depends on Southlake when they need us most. Thank you, to every donor who contributed to these important upgrades to care for women.”

Southlake Foundation’s HERE is Where Cancer Meets its Match campaign supports the Stronach Regional Cancer Centre at Southlake. For more information or to make a donation, visit: southlake.ca/HERE.

Pasteurized milk includes remnants of H5N1 bird flu, U.S. officials say

Published

 on

The U.S. Food and Drug Administration says that samples of pasteurized milk have 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 on Tuesday.

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 (USDA) 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.”

Bird flu is spreading in cows. Are humans at risk? | About That

15 days ago

Duration 8:54

For the first time ever, avian influenza, or H5N1 bird flu, was detected in roughly a dozen dairy cow herds across the U.S. About That producer Lauren Bird explores why scientists and public health officials are concerned about the cross-species transmission and whether humans are now at higher risk.

The polymerase chain reaction (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.

Tests for viable virus underway, agency says

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.

The agency said it has been evaluating milk from affected animals, in the processing system and on the shelves. It said it is completing a large, representative national sample to understand the extent of the findings.

The FDA said it is further assessing any positive findings through egg inoculation tests, which it described as a gold standard for determining viable virus.

Matt Herrick, a spokesperson 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 the 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.
