As the coronavirus outbreak continues to accelerate in the U.S., cleaning supplies are disappearing off the shelves and people are worried about every subway rail, deli counter and toilet seat they touch. 

But how long can the new coronavirus linger on surfaces, anyway? The short answer is, we don’t know. A new analysis found that the virus can remain viable in the air for up to 3 hours, on copper for up to 4 hours, on cardboard up to 24 hours and on plastic and stainless steel up to 2 to 3 days. However, this study, which was published in the preprint database medRxiv on Wednesday (March 11),  has not yet yet been peer-reviewed.

Another study published in February in The Journal of Hospital Infection analyzed several dozen previously published papers on human coronaviruses (other than the new coronavirus) to get a better idea of how long they can survive outside of the body. 

They concluded that if this new coronavirus resembles other human coronaviruses, such as its “cousins” that cause SARS and MERS, it can stay on surfaces —  such as metal, glass or plastic — for as long as nine days (In comparison, flu viruses can last on surfaces for only about 48 hours.)

But some of them don’t remain active for as long at temperatures higher than 86 degrees Fahrenheit (30 degrees Celsius). The authors also found that these coronaviruses can be effectively wiped away by household disinfectants. 

For example, disinfectants with 62-71% ethanol, 0.5% hydrogen peroxide or 0.1% sodium hypochlorite (bleach) can “efficiently” inactivate coronaviruses within a minute, according to the study. “We expect a similar effect against the 2019-nCoV,” the researchers wrote, referring to the new coronavirus. But even though the new coronavirus is a similar strain to the SARS coronavirus, it’s not clear if it will behave the same.

It’s also not clear how frequently hands become contaminated with coronaviruses after touching a sick patient or contaminated surface, according to the study. The World Health Organization recommends washing hands or using alcohol-based hand rubs for decontamination of the hands, the authors wrote.

It’s possible that a person can be infected with the virus by touching a contaminated surface or object, “then touching their own mouth, nose, or possibly their eyes,” according to the Centers for Disease Control and Prevention (CDC). “But this is not thought to be the main way the virus spreads.” Though the virus remains viable in the air, the new study can’t say whether people can become infected by breathing it in from the air,  according to the Associated Press

The virus is most likely to spread from person to person through close contact and respiratory droplets from coughs and sneezes that can land on a nearby person’s mouth or nose, according to the CDC.

Germany: Coronavirus Crisis Leads to More Restrictions, Closures and Cancellations

More than 2,100 Coronavirus cases were confirmed in Germany as of Thursday in the late morning. Activities of many kinds came to a halt. It was all about the virus.

The President of the Federal Republic of Germany, Frank-Walter Steinmeier, had his schedule revised on Wednesday. His staff cancelled appointments, including a visit to a rooming house in Bremen. Steinmeier will not host the heads of state from Estonia, Finland and Slovenia either. This was an event which had been scheduled a long time ago.

No More Visitors at President’s Office

Just like the Berlin Bundestag, the Federal President’s Office does not accept tourists or other visiting groups anymore. The Reichstag’s dome was closed until further notice days ago. The same applies to the opera in Berlin, concert halls and theaters, all because of the Coronavirus.

Berlin’s Governing Mayor Michael Müller, who is Science Senator as well, announced several measures too. A task force consisting of representatives from the German capital’s universities and institutes was established. Its task is to monitor the situation and to implement measures should they become necessary.

Start of Semester Postponed

For now, all conferences and other events connected to the universities were cancelled, including lectures. The institutions also have to check their dates for exams, postpone them if possible or convert on-site exams to online exams, which is what the Technical University already did. The start of the next semester was postponed to April 20th. Students who just returned from high risk regions or countries are being asked to go into quarantine in their homes for two weeks.

Berlin’s House of Representatives is now closed to tourists and visiting groups as well. Its President Ralf Wieland signed a list of measures which includes the cancellation of all public events, except for an exhibition in front of the building. Starting right now, only members, the staff, registered visitors and journalists have access to the House of Representatives.

Angela Merkel’s conservative party, the Christian-Democratic Union (CDU), just cancelled its party congress at which is was going to elect a new party leader. The event was going to take place in Berlin on April 25th, 2020.

Back Door Rule for Buses

“The parliament in Berlin needs to remain capable of acting”, Wieland stated. “Therefore it is necessary to minimize the risk of infection to members and the staff in the House of Representatives.”

Berlin’s largest public transport provider BVG is working on changes as well. They are supposed to protect those who are in direct contact with thousands of passengers every day, namely bus drivers. From now on, bus passengers may enter the vehicles through their back doors only. Until now, they had been required to enter through the front door and show their ticket to the driver. Bus drivers will not sell tickets anymore, until further notice. They have to be purchased through apps, in city train stations or BVG customer centers.

Sneezing and Coughing on Public Transport

For the BVG, its board member Rolf Erfurt said the company was convinced that the passengers would show understanding for this measure which had been suggested by experts. It was designed to lower the probability of infection for both bus drivers and passengers. Berlin needed to be mobile in these difficult times.

Through its information systems, including screens inside all U-Bahn trains (subway, underground, metro), BVG is conveying messages about the right behavior during the Coronavirus crisis, including the proper way to sneeze and cough. Everyone on the BVG’s vehicles needed to cough or sneeze into the crook of their arm. That way the risk of infection would be decreased as much as possible.

Coronavirus Affects Berlin’s Night Life

Berlin is known as a party city. Now the Coronavirus crisis is affecting the city’s clubs as well. According to the ‘Clubcommission’, a network set up by club owners, the number of club visitors is already decreasing substantially. Mandatory closures would lead to many bankruptcies, the commission said. At the same time a shutdown for a few weeks was probably necessary because of the spread of the virus. Some club owners have already cancelled parties and events. For now, club visitors will be registered. Starting this weekend, all of them will have to register with their e-mail addresses and phone numbers.

In Germany’s second-largest city, Hamburg, the number of infections is on the rise, just like in Berlin and everywhere else. Within one day, it increased by 19 to 54. The Hamburg authorities announced a number of measures as well. One about events with more than 1000 people would be communicated very soon, a statement read. The health authorities were also in the process of developing rules smaller events in Hamburg.

Protecting Hamburg’s Schools and Kindergartens

In order to protect Hamburg’s schools and kindergartens, a new rule says that children, with or without the typical symptoms, who return from high risk areas or countries with their families have to be in quarantine for 14 days before they go back into their classes or groups. All other individuals who return to Hamburg from those regions need to quarantine themselves for two weeks as well. Most other city states and provinces in Germany have come up with similar rules by now.

All over Germany, many schools are closed. The latest case was reported from Worms, where a Coronavirus case led to the closure of a large school with 4500 students. In one grade, all pupils are being tested.

Dealing with Trump’s Travel Ban

The total number of Coronavirus cases exceeded 2,100 on Thursday before noon. Some 900 of those were registered in North Rhine-Westphalia, 366 in Bavaria and 335 in Baden-Württemberg. Berlin had 118 confirmed cases on March 12th, 2020, at 11:45 a.m..

Sixty-one of them were men, 56 women, and in one case the gender was not announced. One of those infected lives in a refugee hostel. In a television interview, Berlin’s Governing Mayor Michael Müller said it had probably been a mistake not to take decisions on restrictions regarding big events earlier. He said the government needed to look into Deutsche Bahn, Germany’s main train operator. The question was whether train connections and stops needed to be restricted as well.

Carnival of Cultures Cancelled

In the meantime, two more big events in Berlin were cancelled, namely one known as ‘Myfest’ which usually takes place on Europe’s labor day, May 1st. The other one is the Carnival of Cultures, one of the most international and colorful events. It was supposed to take place from May 29th to June 1st, 2020.

Europe’s airlines, including Germany’s flag carrier Lufthansa, will have to adapt to the travel ban from Europe to the United States which President Trump just announced. The ban will kick in on Friday. Since the aftermath of September 11th, 2001, there has not been anything of the kind.

Stanford Medical Expert Examines Social Distancing, Bell Curve Of Coronavirus Epidemic

Dr. Bonnie Maldonado
Dr. Bonnie Maldonado

STANFORD (KPIX 5) — Past the point of containment, the best hope is to slow a virus down, or “flatten the curve.” The idea is to keep the virus from spreading so quickly that it overwhelms our health care system’s ability to treat the very sick.

That is what social distancing is designed to do, but where on that curve is the United States now, and where might the country be heading?

“Of course, hindsight is 2020,” says Dr. Bonnie Maldonado, a pediatrician and infectious disease expert at the Stanford School of Medicine. “We never know where we are on the curve, until after the curve has been drawn.”

Maldonado says making any prediction about how the virus will spread in the United States is difficult, because the country is actually watching several different outbreaks at once.

“For example, in new Rochelle, New York, we know that that is a very specific kind of outbreak, and we could maybe pattern that one,” Maldonado explains. “But that has nothing to do with what is happening in Seattle, or in Santa Clara, or any other place. So it’s really hard to scale up a model that would take into account all of the different scenarios across the country.”

In that respect, Maldonado says Italy makes for a problematic comparison with the United States. And while the country has lagged in testing for the virus, there is some encouraging evidence at our hospitals.

“Even with lack of testing, we would probably be noticing a lot more people that are sick,” Maldonado says.

In other words, there has not yet been a dramatic or overwhelming surge in very sick patients. That means social distancing, and the other steps we are taking, could be putting the brakes on the virus, at least enough to keep that curve down.

“We know that from looking at epidemic curves going forward, 3 to 4 days of intervention can make a big difference between a flat epidemic and a peaked one,” Maldonado says of mitigation strategies like social distancing. “I do think we will be able to limit the spread, I just don’t know where it will stop.”

Ireland reports first death from coronavirus

Irish Authorities have been criticized for their slow response to the Coronavirus Pandemic.


DUBLIN (Reuters) – Ireland’s Health Ministry confirmed its first death of a patient diagnosed with the coronavirus on Wednesday.

The patient was one of the 34 confirmed cases in Ireland as of Tuesday. The health department will provide its daily update of the number of cases at 1800 GMT.

The Irish Times newspaper reported that the elderly woman who died initially presented at a hospital in the east of the country with respiratory symptoms and was diagnosed with the disease when staff performed a test.

“We continue our efforts to interrupt the transmission of this virus. It will take all of us, collectively to succeed,” Ireland’s chief medical officer, Tony Holohan, said in a statement.

Two more cases were identified on Wednesday in Northern Ireland, the British region which shares an open border with the Irish republic, bringing the total there to 18, Northern Ireland’s health department said.

The head of Ireland’s Health Service Executive, Paul Reid, also said on Wednesday that the country was entering a new phase in the spread of coronavirus and that he fully supported some hospitals that had decided to restrict visitors.

Briton struck with coronavirus in Wuhan recalls: ‘I couldn’t get enough air’

A British Citizen living in Wuhan, China describes his experience with contracting Coronavirus, symptoms, treatment & recovery.

LONDON (Reuters) – Connor Reed was working in Wuhan when he contracted the coronavirus in late 2019, suffering common cold-like symptoms, then flu, and ultimately pneumonia which hospitalized him and left him struggling to breathe.

Now fully recovered after a month of sickness, and still living in Wuhan, where the epidemic first broke out, Welshman Reed, 25, has adapted to the new normal in the city under lockdown since late January.

“I first had a cold – just an everyday cold, a thing that everybody gets. I then got better before I got worse. So from the cold I progressed into the flu … definitely the worst flu that I’ve had.”

“From the flu. I got better again, and that’s when I had pneumonia. The pneumonia stage was when I went to the hospital.”

At the time of his admission, authorities in China were not fully aware of the scale of the outbreak of the new virus. Reed got confirmation at the end of December that he had COVID-19.

“When I had the flu symptoms, that felt like I’d been hit by a truck. And it was quite debilitating … however, it wasn’t life threatening.”

“When I had pneumonia, that’s the point where it was getting quite serious. It felt like I could only use half my lung capacity, and every breath I took wasn’t enough and I just couldn’t get enough air.”

Reed said it sounded like he was breathing through “a paper bag” and as if there was stuff in his lungs that wouldn’t shift.

But as a young man who wasn’t in a critical state and with the hospital facing an influx of people, Reed was sent home to rest. He is now looking forward to the lockdown slowly lifting and expects the quarantine to ease by the middle of next month.

Chinese authorities feel the tide is turning in their favor and some vital industries in Wuhan were told they can resume work on Wednesday, a day after President Xi Jinping visited there for the first time since the outbreak began.

“If they release a quarantine too early … we’ll be back to square one. It’s better to be overly cautious than not cautious enough,” said Reed.

“Everything’s changed, from how we go shopping to how we manage the house … Everybody’s taken the time to adjust and we all have adjusted. It’s a case of people doing the best with what they have,” he said.

He believes the Chinese government has dealt with the epidemic as well as it could, and because of the nature of Chinese society, it could take strict measures which people would adhere to.

As the outbreak accelerates outside China, Reed says: “Other governments definitely can learn from it. However, each individual country and individual government has different responsibilities and different things that they can do.”

“Also, people individually, they have to manage it themselves and take their own precautions. They can’t rely on the government too much.”

Some in Wuhan told to go back to work as new cases of coronavirus subside in China

BEIJING/SHANGHAI (Reuters) – Some vital industries in Wuhan, the Chinese city at the epicenter of the coronavirus epidemic, were told they can resume work on Wednesday, a day after President Xi Jinping visited there for the first time since the outbreak began.

The city of 11 million has been in lockdown since late January but Xi’s visit signaled the tide was turning in the government’s favor as it fights to contain a virus that as of Tuesday had infected 80,778 people in China and killed 3,158.

Authorities elsewhere in China lowered emergency response levels to the epidemic and relaxed travel restrictions.

Drawing confidence from Xi’s visit and falling new infections, the Hubei provincial government said public transport workers in Wuhan and those engaged in making medical supplies and producing daily necessities would be allowed to return to work.

Other industries that impact national or global supply chains can also return to work with permission from relevant authorities, it said.

Wuhan accounts for nearly 10% of vehicles made in China and is home to hundreds of parts suppliers. Across the country, manufacturing is slowly returning to normal.

Though the economy is still operating at about 25% below its usual levels, activity should be fully restored by the end of April, Francoise Huang, senior economist at Euler Hermes, predicted in a note to clients.

On Wednesday, Japanese automaker Nissan said it planned to partially resume production at two Chinese plants, one of them in Hubei. Its competitor Honda said that some employees had returned to work at its plant in Wuhan, and that it would gradually restart production from Wednesday.

In a gesture to further boost investor confidence, the National Development and Reform Commission (NDRC) said on Wednesday it will actively help foreign-invested firms resume work and expand sectors in which foreign investment in encouraged.

While relaxing some restrictions, the Hubei government said curbs on transport in Wuhan would remain in place, and schools in the province would remain closed until further notice.

The city of Qianjiang in Hubei also bucked a wider loosening trend, with authorities saying they would retain strict transport bans.

Latest figures from the National Health Commission showed 24 new coronavirus cases nationwide, and 22 more deaths as of Tuesday. All the latest deaths occurred in Wuhan.

But new infections in Hubei continued to stabilize, with new cases declining for the sixth day. All 13 new cases in Hubei were recorded in Wuhan.


The most encouraging trend to be taken from the latest infection figures was lower rate of transmission within communities in China, as 10 of Tuesday’s 24 new cases involved people traveling from abroad.

But Chinese customs said downward pressure on China’s foreign trade and the global economy is still increasing as the coronavirus epidemic is spreading quickly abroad.

“Stabilizing trade growth would be more difficult,” Customs said in a statement. “Risks of imported cases are suddenly rising, and dealing with coronavirus-related risks at China’s ports would pose a major challenge.”

While only 79 of the cases in China have come from abroad, the rising number of such incidences has prompted authorities to shift their focus on containing the risk of imported cases.

The capital of Beijing saw six new cases on Tuesday involving individuals who traveled from Italy and the United States, while Shanghai had two imported infections, Shandong province one and Gansu province one. The southern province of Guangdong reported three cases involving travelers, one from France and two from Spain.

Elsewhere, however, Hunan province and the municipality of Chongqing lowered their emergency response level, while cities around Shandong province resumed inter-city and rural passenger transportation routes, the official Xinhua news agency reported.

So far, about three-quarters of China’s municipalities, regions and provinces have lowered their emergency response level from the highest tier.

FDA approves Bristol Myers’ liver cancer therapy


(Reuters) – Bristol Myers Squibb’s combination of its immunotherapies, Opdivo and Yervoy, to treat a type of liver cancer received U.S. regulatory approval, the drugmaker said on Wednesday.

The therapy received the Food and Drug Administration’s accelerated approval to treat patients with hepatocellular carcinoma, who have previously been administered sorafenib, the current standard of care. (

The accelerated approval program allows a speedier market entry to medicines that fill an unmet medical need for a serious condition, and further clinical trials may be required for final approval of the therapy.

The FDA approval is based on an early stage trial in which 33% of patients responded to the therapy.

“The incidence of liver cancer is rising in the United States…and today’s approval provides a new option for patients with HCC (hepatocellular carcinoma),” said Andrea Wilson, president Blue Faery: The Adrienne Wilson Liver Cancer Association.

HCC is the most common type of primary liver cancer and is more common in people who drink large amounts of alcohol and who have an accumulation of fat in the liver.
