Discussion and conclusions
--------------------------
As a response to the ongoing outbreak of the 2019-nCoV originating in Wuhan, exit screening has been implemented for international flights leaving China's major airports. Thermal scanning, which can identify passengers with fever (high external body temperature), allows for passengers exhibiting symptoms of 2019-nCoV infection to be tested before they board a plane. Similarly, entry screening for flights originating in the most affected regions may be under consideration at airports in regions in and outside China. We estimate that the key goal of syndromic screening at airports -- to prevent infected travellers from entering countries or regions with little or no ongoing transmission -- is only achievable if the rate of asymptomatic infections that are transmissible is negligible, screening sensitivity is almost perfect, and the incubation period is short. Based on early data from Li et al [8], 2019-nCoV appears to have a shorter incubation period than severe acute respiratory syndrome (SARS), and a higher rate of asymptomatic infections [11]. Under generally conservative assumptions on sensitivity, we find that 46 of 100 infected travellers will enter undetected.

Entry screening is an intuitive barrier for the prevention of infected people entering a country or region. However, evidence on its effectiveness remains limited and given its lack of specificity, it generates a high overhead of screened travellers uninfected with the targeted pathogen [5]. For example, when entry screening was implemented in Australia in response to the 2003 SARS outbreak, 1.84 million people were screened, 794 were quarantined, and no cases were confirmed [12]. While some cases of 2019-nCoV infection have been identified through airport screening in the current outbreak, our estimates indicate that likely more infected travellers have not been detected by screening.

It is important to note that our estimates are based on a number of key assumptions that cannot yet be informed directly by evidence from the ongoing 2019-nCoV outbreak. The current outbreak has spread rapidly and early evidence suggests that the average disease severity is lower than that of SARS. This may also suggest a substantial proportion of asymptomatic cases. A recent analysis of a family transmission cluster is based on a small sample size but one in 6 infections was asymptomatic [11]; this is a major impediment for the effectiveness of syndromic screening. However, if asymptomatic cases were not infectious they would not pose a risk for seeding infection chains on arrival. To allow easy adaptation of our results as new insight becomes available in the coming weeks, we developed a free interactive online tool, available at https://cmmid-lshtm.shinyapps.io/traveller_screening/.

While the most up-to-date data on the incubation period or the time until recovery from 2019-nCoV infection have been used in this analysis, these figures are likely to change over time as more data become available. Unless the incubation period is only a small fraction of the duration of infection in relation to that of symptomatic disease, and fever in particular, syndromic screening is likely to detect an insufficient fraction of infected cases to prevent local infections. In addition, the sensitivity of airport screening for the detection of 2019-nCoV has not been evaluated. However, we chose conservative estimates and show that with reduced sensitivity, the effectiveness of syndromic screening would further decline.

In many international airports, information is provided to travellers from affected regions recommending action if they develop symptoms on or after arrival [13-16]. Some countries, for example Japan, also require incoming passengers to complete forms detailing their past and future travel in order to aid tracing [17]. Due to the duration of the incubation period of 2019-nCoV infection, we find that exit or entry screening at airports for initial symptoms, via thermal scanners or similar, is unlikely to prevent passage of infected travellers into new countries or regions where they may seed local transmission.

C. Singapore local transmission
情報源 The Straits Times  2020年2月5日
Another 4 cases of the coronavirus infection were confirmed by the Ministry of Health (MoH) on [Wed 5 Feb 2020], including the youngest patient confirmed so far, a 6 month old baby who is the child of an infected couple. Of the new cases, 3 are linked to the cluster of local transmissions announced on [Tue 4 Feb 2020], and 1 is an imported case involving a Chinese tourist from China's Wuhan city.

On [Tue 4 Feb 2020], MoH announced 6 confirmed cases of the coronavirus, with 4 women here infected who had not travelled to Wuhan, the epicentre of the virus outbreak.

These 4 cases are linked to a group of 20 tourists from Guangxi, China, that visited health products shop Yong Thai Hang in Cavan Road in Lavender. With the cases announced on [Wed 5 Feb 2020], the number of cases linked to the tour group is now 7. MoH said the Chinese health authorities have confirmed that 2 travellers from the tour group have the coronavirus infection.

It reiterated that there is no evidence of widespread community transmission in Singapore for now. Wednesday's [5 Feb 2020] announcement means that the total number of confirmed cases in Singapore is 28. All 4 new cases are in stable condition, while 22 cases confirmed earlier are stable or improving, and 1 case has been discharged, said MoH. The remaining case needs extra oxygen support, but is not in the intensive care unit.

Outside China, Singapore has the 2nd highest number of confirmed cases of the coronavirus. Japan has the most with 33 cases so far.

Details of new cases
--------------------
The 4 new cases announced here on [Wed 5 Feb 2020] include a father and son -- a Singaporean man and his baby boy. His wife and their maid were earlier confirmed to be infected. The 3rd new case is the Singaporean husband of an infected tour guide, while the 4th is a tourist from China. The father and son, as well as the husband of the tour guide, are among the 7 confirmed cases linked to a tour group that visited the Yong Thai Hang shop.

1st case: The baby boy, who is Singaporean and 6 months old, is the son of a woman who works at Yong Thai Hang, which caters to Chinese tour groups. He is warded in an isolation room at KK Women's and Children's Hospital. MoH said the baby was not in any infant care facility before he was hospitalised -- he was cared for at home. His 28 year old mother is a Singapore permanent resident who did not recently travel to China. On [Tue 4 Feb 2020], MoH confirmed that she and their foreign domestic helper, a 44 year old Indonesian woman, were infected with the coronavirus. This was after Yong Thai Hang was visited by a tour group from Guangxi on [23 Jan 2020]. The Singaporean tour guide of the group was later confirmed to be infected.

2nd case: The baby's father was also one of the confirmed cases announced on [Wed 5 Feb 2020] with no recent travel history to China. The 45 year old Singaporean man is warded in an isolation room at the National Centre for Infectious Diseases (NCID).

3rd case: Another case confirmed on [Wed 5 Feb 2020] linked to the Chinese tour group that visited the shop is the husband of the group's infected tour guide. The 40 year old Singaporean man also had not travelled to China recently, and is currently warded in an isolation room at NCID. He developed a fever on [24 Jan 2020] and visited Hougang Polyclinic with his wife, a 32 year old Singaporean woman, on [30 Jan 2020]. He went to NCID on [Mon 3 Feb 2020]. Before the man was admitted to hospital, he was at his home in Buangkok Green and worked at Diamond Industries Jewellery Company at Harbour Drive which was visited by the same tour group from Guangxi. The man also visited Pasir Panjang Hawker Centre and used public transport. MOH said that the risk of infection from transient contact, such as on public transport or in public places, is assessed to be low.

4th case: The last confirmed case announced on [Wed 5 Feb 2020] is a 42 year old Chinese national who arrived in Singapore from Wuhan on [21 Jan 2020]. She is the daughter of one of the earlier confirmed cases, a 73 year old woman who is also a Chinese national. As the 42 year old showed symptoms, she was taken by ambulance to NCID on the same day as her mother, immediately isolated, and is now warded in an isolation room at the centre.

Tour group from Guangxi
-----------------------
Regarding the tour group from Guangxi that visited the Yong Thai Hang shop, MOH said that the group was in Singapore from [22-23 Jan 2020], and also transited here for 3 hours on [27 Jan 2020] before leaving the country. The group also visited 5 other places here: Diamond Industries Jewellery Company in Harbour Drive; Meeting You Restaurant in Hamilton Road; Royal Dragon Restaurant in Havelock Road; T Galleria by DFS in Scotts Road; and D'Resort at Downtown East in Pasir Ris. Almost 14 days have passed since the tourists visited these places, and MoH has communicated with 142 contacts. All of these contacts are well except for one who has been isolated as a suspected case. Test results for this person are pending.

The ministry has also done contact tracing for the crew and passengers of the flight that left Singapore with the Chinese tour group on [27 Jan 2020]. 5 of them are still in Singapore and have been quarantined.

Overseas cases linked to Grand Hyatt Singapore
----------------------------------------------
On [Wed 5 Feb 2020], 3 business travellers -- a Malaysian and 2 South Koreans -- linked to a conference at the Grand Hyatt Singapore they attended last month [January 2020], were reported to have tested positive for the coronavirus. The 2 South Korean men had come into contact with the Malaysian, who was infected. Details on how, where and when the Malaysian man became infected were not revealed by MoH. The ministry said that this private business meeting at the hotel from [20-22 Jan 2020] involved 109 people from the same company. Of the 15 Singapore residents at this event, 11 are well. 4 have reported symptoms and were referred to NCID for assessment. The event's remaining 94 overseas participants have since left Singapore and MoH has informed the relevant health authorities abroad.

In Singapore, measures to combat the outbreak include mask distribution at residents' committee centres and community centres islandwide, which began last [Sat 1 Feb 2020]. The government announced on [30 Jan 2020] that all 1.3 million households in Singapore would be given a pack of 4 masks each amid reports of shops running out of stock. On [Tue 4 Feb 2020], it also said that large gatherings and communal activities, such as assemblies and excursions, will be suspended at schools, pre-schools and eldercare facilities here from [Wed 5 Feb 2020], after the 1st local transmissions of the coronavirus were reported.

MoH said on [Wed 5 Feb 2020] that 295 suspected cases have tested negative for the virus so far. Test results for 62 more cases are pending. The ministry has identified 379 close contacts of the confirmed cases. Of these, 304 are still in Singapore, with 299 contacted and being quarantined or isolated. Efforts are being made to contact the remaining 5 close contacts.

MoH continues to advise Singaporeans to defer all travel to Hubei province and all non-essential travel to mainland China. Members of the public should also observe good personal hygiene such as frequently washing their hands with soap. They should also wear a mask if they have respiratory symptoms such as a cough or shortness of breath, and seek medical attention promptly if they are feeling unwell.

[6] Death of physician whistle-blower in Wuhan
Date: Fri 7 Feb 2020
Source: The New York Times [edited]
https://www.nytimes.com/2020/02/06/world/asia/Li-Wenliang-coronavirus.html


Chinese doctor, silenced after warning of outbreak, dies from coronavirus
-------------------------------------------------------------
Dr Li Wenliang issued a warning about a strange new virus. Then the authorities summoned him for questioning. He was the doctor who tried to sound a warning that a troubling cluster of viral infections in a Chinese province could grow out of control -- and was then summoned for a middle-of-the-night reprimand over his candor.

On [Fri 7 Feb 2020], the doctor died after contracting the very illness he had told medical school classmates about in an online chat room, the coronavirus. He joined the more than 600 other Chinese who have died in an outbreak that has now spread across the globe.

Dr Li "had the misfortune to be infected during the fight against the novel coronavirus pneumonia epidemic, and all-out efforts to save him failed," the Wuhan City Central Hospital said on Weibo, the Chinese social media service. "We express our deep regret and condolences."

Even before his death, Dr Li had become a hero to many Chinese after word of his treatment at the hands of the authorities emerged. In early January [2020], he was called in by both medical officials and the police, and forced to sign a statement denouncing his warning as an unfounded and illegal rumor.

Dr Li, who was 34 and expecting a 2nd child with his wife, had been a relatively obscure ophthalmologist in Wuhan, the capital of Hubei Province and the epicenter of the coronavirus epidemic. Dr Li's death has also exposed a troubling aspect of the epidemic that goes unmentioned in official statistics: the number of doctors, nurses, and medical workers infected by the virus.

Some unverified pictures of what appear to be government data have indicated that hundreds of hospital workers may have been infected in Wuhan. Earlier in the outbreak, a prominent infectious disease expert said that a single patient had infected 14 medical workers at one hospital.

Dr Li was also unusually young to be afflicted by the virus, at least according to the data gathered so far. The median of patients is between 49 and 56, researchers say.

When Dr Li posted his chat room warning on [30 Dec 2020], the new coronavirus had not yet been identified. He said it resembled severe acute respiratory syndrome, or SARS, an earlier coronavirus that ravaged China nearly 2 decades ago. Not long after his reprimand, Dr Li was vindicated as thousands of Wuhan residents fell ill with fever and pneumonia symptoms. He joined their number after contracting the virus from a patient he was treating for glaucoma.

Dr Li's death came after a night of speculation about his fate, including an online outpouring of grief in China prompted by premature reports that he had died. Just hours before confirming that he had died, the hospital said on Weibo that it was still fighting to save him. Soon after Dr Li's death was announced, the Hubei Province Health Commission issued a brief message offering condolences, and so did the health authorities of the city of Wuhan. Global Times, a reliably pro-government tabloid, also mourned the death, while also urging readers to support the government's fight against the epidemic. "That Li Wenliang could not escape having his life snatched away shows that this is an arduous and complex battle," an online article in Global Times said. "At this critical juncture, all of us must be united."

Dr Li's death appeared unlikely to inspire protests in Wuhan, which has been under lockdown for just over 2 weeks in an unprecedented effort to extinguish the epidemic. In Wuhan and other heavily restricted areas of Hubei, residents mostly stay inside their homes and avoid socializing for fear of catching the virus. Much of the rest of China is also under tight restrictions that make mass displays of mourning unlikely. Dr Li continued to speak out during his own illness.

WHO is working with partners to strengthen global diagnostic capacity for 2019-nCoV detection to improve surveillance and track the spread of disease. Public health efforts to control the spread of disease in countries with imported cases depend critically on the ability to detect the pathogen quickly. WHO and partners have activated a network of specialized referral laboratories with demonstrated expertise in the molecular detection of coronaviruses. These international labs can support national labs to confirm new cases and troubleshoot their molecular assays.

Currently, there are 15 laboratories have been identified to provide reference testing support for 2019-nCoV. These laboratories include:
1. Armed Forces Research Institute of Medical Sciences, Thailand
2. Erasmus Medical Center, The Netherlands
3. Hong Kong University, Hong Kong SAR, China
4. Institute of Tropical Medicine, Nagasaki University, Japan
5. Institute of Virology, Charité, Robert Koch Institute, Germany
6. National Institute for Communicable Diseases, South Africa
7. National Institute of Health, Thailand
8. National Institute of Virology, India
9. National Public Health Laboratory, Singapore
10. Institut Pasteur Dakar, Senegal
11. Institut Pasteur, Paris
12. Public Health England, UK
13. State Research Center for Virology and Biotechnology, Vector Institute, Russia
14. United States Center for Disease Control and Prevention, USA
15. Victorian Infectious Diseases Reference Laboratory, Australia

WHO is working to ensure 2019-nCoV test availability, including:
a. screening of 2019-nCoV PCR protocols from academic laboratories for validation data,
b. evaluation of the potential to use existing commercial coronavirus assays (for example, SARS-CoV. to detect 2019-nCoV with high sensitivity, and
c. working with commercial and noncommercial agencies with capacity to manufacture and distribute newly-developed 2019-nCoV PCR assays.

To increase regional testing capacity, efforts to increase national capacity and provide regional reference laboratory support is ongoing. WHO has made 250,000 tests available to WHO Regional Offices and national laboratories. These tests are being shipped to 159 laboratories across all WHO regions.

WHO will also utilize the Shipping Fund Programme established by the Global Influenza Surveillance and Response System as a mechanism to send clinical samples from patients meeting the case definition of suspected 2019-nCoV infection to international referral laboratories.

National capacity for detection of 2019-nCoV must be strengthened so that diagnostic testing can be performed rapidly without the need for overseas shipping. One way this will be achieved is by working with existing global networks for detection of respiratory pathogens, such as National Influenza Centres.

WHO to accelerate research and innovation for new coronavirus
-------------------------------------------------------------
WHO is convening a global research and innovation forum to mobilize international action in response to the new coronavirus (2019-nCoV).
"Harnessing the power of science is critical for bringing this outbreak under control," said WHO director-general Dr Tedros Adhanom Ghebreyesus. "There are questions we need answers to, and tools we need developed as quickly as possible. WHO is playing an important coordinating role by bringing the scientific community together to identify research priorities and accelerate progress."

The forum, to be held [11-12 Feb 2020] in Geneva, is organized in collaboration with the Global Research Collaboration for Infectious Disease Preparedness. The forum will bring together key players including leading scientists as well as public health agencies, ministries of health and research funders pursuing 2019-nCoV critical animal health and public health research and the development of vaccines, therapeutics and diagnostics, among other innovations.

Participants will discuss several areas of research, including identifying the source of the virus as well as sharing of biological samples and genetic sequences. Experts will build on existing SARS and MERS coronavirus research and identify knowledge gaps and research priorities in order to accelerate scientific information and medical products most needed to minimize the impact of the 2019-nCoV outbreak.

The meeting is expected to produce a global research agenda for the new coronavirus, setting priorities and frameworks that can guide which projects are undertaken first. "Understanding the disease, its reservoirs, transmission and clinical severity and then developing effective counter-measures is critical for the control of the outbreak, to reduce deaths and minimize the economic impact," said Dr Soumya Swaminathan, WHO chief scientist.

This will also fast-track the development and evaluation of effective diagnostic tests, vaccines and medicines, while establishing mechanisms for affordable access to vulnerable populations and facilitating community engagement.

"The WHO R&D Blueprint is a global strategy and preparedness platform that drives coordinated development of drugs and vaccines before epidemics, and allows the rapid activation of R&D activities during epidemics. It speeds up the availability of the diagnostics, vaccines and treatments and technologies that ultimately save lives," added Dr Michael Ryan, executive director, WHO Health Emergencies Programme. Setting clear global research priorities for the novel coronavirus should lead to more efficient investments, high-quality research and synergies among global researchers.
