  A&Es on 'heightened alert' after suspected China coronavirus case leads to decontamination A suspected case of the new killer Chinese corona­virus sparked concern among paramedics at a Dublin A&E, leading them to carry out a decontamination exercise, it emerged yesterday. The health scare emerged after ambulance staff brought the patient, who had a fever and had returned from China, to the A&E of the Mater Hospital on Tuesday.

The question is: do they work?

Many infectious disease specialists say the cheap disposable masks, which cover the nose and mouth, may help prevent the spread of infections if they are worn properly and used consistently.

But there isn’t much high-quality scientific evidence on their effectiveness outside health care settings, experts say. Most of the best studies, which are randomized controlled trials, focused on how well surgical masks protect health care workers in hospitals from picking up infections from sick patients, and found that consistent use of them helped.

China virus: 25 dead as Wuhan city in lockdown

  China virus: 25 dead as Wuhan city in lockdown The number of people killed by a new virus in China has risen from 25 - and overall cases to 616, the country has said. It comes as millions of people prepare to travel domestically and abroad for the country's lunar new year celebrations which begin at the weekend.The city of Wuhan, where the coronavirus is believed to have originated, is in lockdown.All its transport networks - including rail, bus, underground and ferries - have been suspended, and its 11 million residents have been ordered to wear masks in public places and at work.

But, coronavirus was identified in China last month and monitored closely. “The recent outbreak of novel coronavirus pneumonia in Wuhan and other places must be taken As the virus continues to spread, many are wondering the exact nature of coronavirus , what it entails, and where it all started.

China ’s National Genomics Data Center said the Wuhan virus was 88 percent genetically similar to a SARS-like coronavirus that was collected from bats in China in 2017. Still another group of Chinese scientists suggested that snakes were the “ most probable wildlife animal reservoir” for the novel

Dr. Julie Vaishampayan, chairwoman of the public health committee for the Infectious Diseases Society of America, said surgical masks are really “the last line of defense.”

GPs will get face masks and gowns as virus fears grow

  GPs will get face masks and gowns as virus fears grow Irish GPs are to be provided with full head-to-toe protective gowns and masks next week after warning the failure of the HSE to provide safety gear left them at risk of the deadly coronavirus. It follows growing concern about the virus threat here, following the detection of the first two cases of the killer infection in the UK.The HSE confirmed that the packs will be sent to GP surgeries after angry doctors' protests and the revelation that two Chinese tourists staying in an English hotel are infected with the virus.

“We worry about people feeling they’re getting more protection from the mask than they really are,” she said. “Washing your hands and avoiding people who are ill is way more important than wearing a mask.”

Because surgical masks aren’t fitted or sealed, they leave gaps around the mouth, “so you’re not filtering all of the air that comes in,” she said.

The masks will, however, block most large respiratory droplets from other people’s sneezes and coughs from entering your mouth and nose, said Dr. Amesh Adalja, an infectious disease physician at the Johns Hopkins Center for Health Security. Coronaviruses are primarily spread through droplets, he said.

The bigger problem is that people don’t use the masks properly. “Most people will put their hand underneath the mask to scratch their face or rub their nose,” bringing contaminants in contact with the nose and mouth, said Dr. Adalja. “You can’t take it off when you get a phone call.”

  Many in China Wear Them, but Do Masks Block Coronavirus? © Getty Dr. Mark Loeb, an infectious disease specialist at McMaster University in Hamilton, Ontario, said a study during an outbreak of the SARS coronavirus found that any type of protection — whether a mask or a respirator — reduced the risk of infections in health care workers by about 85 percent.

“The most important message was that the risk was lower if they consistently used any mask,” he said.

There is general agreement that infected patients who wear surgical masks are less likely to spread infection to others. The Centers for Disease Control and Prevention has instructed hospitals to ask any patients who have a fever or respiratory illness, have recently traveled to Wuhan, or have come in contact with someone who has traveled there, to wear a surgical mask. The C.D.C. also recommends that health care workers wear a respirator, which filters out more particles than a mask, when they are around such patients.

The risk of becoming infected with the coronavirus in the United States — where there is only one confirmed case — is “way too low to start wearing a face mask,” said Dr. Peter Rabinowitz, who is co-director of the University of Washington MetaCenter for Pandemic Preparedness and Global Health Security.

But washing hands — frequently and before eating — is universally recommended. Hand sanitizer is effective against respiratory viruses. Experts also recommend washing hands with soap and water for at least 20 seconds, rubbing the hands together and ensuring all parts of the hands — the palms as well as the back of the hands — are washed.

“It’s also important to keep your hands away from your face,” said Dr. Vaishampayan. “Respiratory viruses don’t infect through your skin, they infect through your mucous membranes: the eyes, nose and mouth.”
