Professor Ben Cowling on the effectiveness of a face shield 

Professor Ben Cowling from the School of Public Health said he doesn’t think a face shield would be as effective as a mask for this pandemic. While a shield could protect the wearer from large droplets, he said, it wouldn’t prevent them from spewing the virus.

HKUMed Research: coronaviruses do not readily induce cross-protective antibody responses

"Our findings, albeit limited at present, would suggest that broadly cross-neutralizing antibodies to coronaviruses might not be commonly produced by the human immune repertoire," says Dr Chris Mok, Research Assistant Professor at the School of Public Health. "Moving forward, monoclonal antibody discovery and characterization will be crucial to the development of a SARS-CoV-2 vaccine in the short-term, as well as a cross-protective coronavirus vaccine in the long term."

HKUMed study discovered a mechanism that may explain why some COVID-19 patients temporarily lose sense of smellby using a golden hamster animal model

“Our findings support the recent changes in the criteria used in Hong Kong for discharge of COVID-19 patients from hospital isolation,” said Dr Yen Hui-ling, Associate Professor of School of Public Health. 

“The viral damage to the nasal epithelium and neurons associated with the sense of smell may not only explain the mechanism of the loss of sense of smell reported by infected patients, but also shows that, at least in the animal model, the damage is not likely to be permanent,” said Professor John Nicholls, Clinical Professor at the Department of Pathology.

HKUMed research suggests that eyes may be an important route of SARS-CoV-2 human infection

HKUMed researchers discovered that novel coronavirus can infect more efficiently than SARS-CoV in human airways and eyes, implicating that eyes may be an important route of SARS-CoV-2 human infection.

“We culture tissues from the human respiratory tract and eyes in the laboratory and applied them to study the SARS-Cov-2, comparing it with Sars and H5N1. We found that SARS-Cov-2 is much more efficient in infecting the human conjunctiva and the upper respiratory airways than Sars, with virus level some 80 to 100 times higher. This explains the higher transmissibility of COVID-19 than that of SARS. This study also highlights the fact that eyes may be an important route of SARS-CoV-2 human infection,” said Dr Michael Chan Chi-wai of HKUMed.

Coronavirus particles can possibly linger in air but not main risk for infection, says Professor Malik Peiris

According to Professor Malik Peiris, a clinical and public health virologist at HKUMed, viral particles being shaken into the air is possible, but would not be the main risk for regular people when it came to viral spread, noting that the difference was related to the concentration of the virus on surfaces compared to in the air. “The bigger risk is that if you take your mask off you touch the front of the mask and don’t wash your hands and touch your eyes, that’s a much bigger risk than whatever is shaken out into the air. These are proportionate issues,” he said.

Whether antibodies resulting in seropositivity provide any protection against re-infection is still unknown, said Professor Joseph Wu

“While seropositivity ... is a good proxy for infective exposure, it does not necessarily indicate seroprotection,” said Professor Joseph Wu from the School of Public Health. “This means we don’t know whether the antibodies that result in seropositivity provide any protection against re-infection.” Studies that take a snapshot of seroprevalence at a particular time and place are instead useful as ways of “estimating the proportion of true infections that have been under-reported,” he added, which in turn can be used to more accurately estimate infection rates in the future.

No country is going to want to open up too early, and then be the first major country to have a big second wave,” Professor Benjamin Cowling from HKUMed School of Public Health told CNBC’s Street Signs Asia. “I think it’s going to be very difficult because we know that even countries that overcome their first wave, they’re going to have challenges from other countries who are still experiencing their first wave or even experiencing a second wave, which could be starting now in China.”

Vaccines can't be rushed - Professor John Nicholls

"Normally with vaccines you start off with small animals and then move to primates and then to the humans," Professor John Nicholls, pathologist at HKUMed, told Al Jazeera. "It seems that with this one they have gone straight to the humans, which is a very bold decision." He added, Most of the mortality in this disease is in the elderly, so the best thing would be to actually see what the anti-body response is in the elderly rather than the young."

There are 'three control knobs' on containing the outbreak, says Professor Gabriel Leung

To regulate R (effective reproduction number), “Governments will have to realize that there are basically three control knobs on the dashboard,” said Professor Gabriel Leung, HKUMed Dean: isolating patients and tracing their contacts, border restrictions, and social distancing. He also talked about the use of technology in contact tracing: “Public health departments, not generally known anywhere in the world to be at the forefront of technological innovation, will have to adapt very quickly.”

Hong Kong can "breathe a little easier" if the drop in new cases continues - HKUMed Dean

If the trend of slowing rate of new cases continues, “we might be able to breathe a little bit easier” and relax the new regulations, said Professor Gabriel Leung, Dean of HKUMed. He also mentioned the role medical scientists have played in Hong Kong's responses against COVID-19: "Both the Hong Kong and Singapore governments do care deeply [about scientific evidence] and listen to scientists.”

Professor Benjamin Cowling on how long a COVID-19 patient can be infectious

It's not fully known how long a person with COVID-19 is infectious, but "a rough guide for other infections is that infectiousness drops when the fever subsides," said Professor Benjamin Cowling from the School of Public Health. He added that studies are underway to evaluate how long the body continues to shed the virus after someone starts to get better, but it should be noted that there is not a direct link between shedding and infectiousness.

Study from HKUMed Microbiology says the virus might linger around for months

“We have seen that [Covid-19] acts like a ninja, it can evade the detection of the body without triggering a very strong reaction, like inflammation, in the body, so it can replicate to a very high level,” said Dr Jasper Chan from HKUMed Department of Microbiology.

“In some cases, Sars-CoV-2 could replicate by about 100 times within 48 hours, while the Sars virus may have peaked at about 10 to 20 times of replications,” said Dr Chu Hin.

Professor Yuen Kwok-yung said: "Even if the epidemic dies down a little bit during summer, with such a low ... immunity, the virus will still continue to spread. [...] Now I think the answer probably is that we try to increase our testing capacity, make sure that you're really not carrying the virus, you continue to wear the mask, you continue to have very good hand hygiene, you have an infection control supervisor in every office of classroom to make sure these are done properly, to allow society to continue."

Balance between economic activities and control measures likely needed until vaccine is made available, says Professor Joseph Wu

"While these control measures appear to have reduced the number of infections to very low levels, without herd immunity against Covid-19, cases could easily resurge as businesses, factory operations, and schools gradually resume and increase social mixing, particularly given the increasing risk of imported cases from overseas as Covid-19 continues to spread globally," said Professor Joseph Wu from HKUMed School of Public Health. "Although control policies such as physical distancing and behavioral change are likely to be maintained for some time, proactively striking a balance between resuming economic activities and keeping the reproductive number below one is likely to be the best strategy until effective vaccines become widely available."

Professor John Nicholls: social distancing and quarantining seems the best method for now 

"Both this coronavirus and also Sars (severe acute respiratory syndrome) did emerge in winter. So, it does tend to indicate that this may be seasonal... In the laboratory, we've shown that this virus is very temperature-dependent - it's very stable at cold temperatures, but at warm temperatures, it can actually be inactivated. The question is what happens outside the lab, in the environment?" said Professor John Nicholls, Clinical Professor in Pathology at HKUMed. "The best method which we have now, which has been used all around the world, is the social measures (such as) social distancing and quarantining. That's about the best that we have to try and keep this virus at bay."

But he also added that other countries might be facing different challenges, such as the multiple outbreaks in the US: "It's possible that New York could be coming out of lockdown, having got the numbers to a low level. But there are other cities where they're having a lot more infections, and it is going to be very difficult to have travel restrictions [...] So it really is a urgent question to figure out what's the best way to suppress transmission across the whole of the U.S."

“On the one hand, I have seen how some businesses have shifted from making alcoholic beverages to making alcohol-based hand sanitizers.

Such machines are complex, will depend on specialized machinery, skilled workers and supplies from a variety of countries,” he added.

Professor Benjamin Cowling: Masks could give you some protection, if worn correctly

“It doesn’t make sense to imagine that […] surgical masks are really important for health care workers but then not useful at all for the general public,” says Professor Benjamin Cowling. “I think the average person, if they were taught how to wear a mask properly […] would have some protection against infection in the community.” But  he also argues that the greatest benefit of masking the masses likely comes not from shielding the mouths of the healthy but from covering the mouths of people already infected.

“The suppression-and-lift strategy is the most talked about amongst my ilk and in governments all over the world,” said Professor Gabriel Leung, Dean of HKUMed. “You would need to keep on these control measures to varying degrees until one of two things happen: One, is there is natural immunity by active infection and recovery, or there is sufficiently wide availability of an effective vaccine administered to at least half the population, to create the same effective herd immunity. These are the only two ways of going about it.” Leung added that we’ll go through “several cycles” of tightenings and easings “before we will have resolution.”

Professor Benjamin Cowling suspects wider COVID-19 outbreak in some countries than reported

Professor Benjamin Cowling, head of the Epidemiology and Biostatistics Division at the School of Public Health, said he suspects wider outbreaks exist in countries that already have confirmed cases, such as Thailand and Vietnam. “Most of the typically hot countries, we think, have not been testing as aggressively as some of the colder ones have been,” he said.

Emphasis should be on preventing community transmissions. says Professor Benjamin Cowling

“Stopping travel will have no material impact on the trajectory of the pandemic’s developments from a public health point of view,” said Professor Benjamin Cowling, from the School of Public Health. “The focus should be more on reducing community transmissions."

"Controlling Coronavirus Will Mean Keeping People Apart" writes Professor Benjamin Cowling Writes in Foreign Affairs

"Now is the time to plan for this eventuality and to consider which measures would be most feasible and effective in reducing transmission. Public health agencies should take advantage of the brief, remaining window to determine exactly what should prompt the most drastic measures (for example, school and workplace closures); how to know when the time is right to implement them; and how long they might need to be kept in place. The key to maintaining public compliance and support for social distancing will be to effectively communicate what the plan is and why it is necessary." said Professor Benjamin Cowling.

Professor Gabriel Leung, Dean of HKUMed, also said the same: "What I have, in fact, seen is that places with very different climates than we have, such as Singapore and Thailand, they are enjoying weather that we usually enjoy in the summer, and yet their numbers are higher than ours. So I wouldn't rely, as a principle means of combatting this particular epidemic, on climatic factors."

"We think this could be in the range 10% to 30%, which would be similar to the severity of hospitalized cases of SARS and MERS.
