Mathematical modelling suggests Hong Kong is at a critical point in the fight against Covid-19. Two factors relate to the growth of the outbreak. Delays in the confirmation of test results, and the delay of contact tracing. The contact tracing system is not keeping up with the large number of daily cases. Thus, the city needs more intensive care beds. There is also an urgent need to increase staff and facilities for Covid-19 testing, so that everyone entering Hong Kong can be tested, especially those who are not quarantined.
<Original article is available at South China Morning Post, https://www.scmp.com/comment/opinion/article/3095460/what-hong-kong-can-do-avoid-total-lockdown-and-fourth-wave-covid-19> I was honour to be join this COVID-19 interview at Radio Television Hong Kong (RTHK) 3 to talk about the current situation of COVID-19 in Hong Kong. There is an unusual large spike occurring after 21 consecutive days without local infections. I discuss the current risk factors and suggest certain public health interventions to control this current outbreak.

We celebrate with nice Taiwanese foods, bubble teas, and Chocolate from Venchi. Finally, we still have a last presentation from him!!  During the forum, I shared my modelling results on how to prevent resurgence of COVID-19 after the relaxation of measures. Understanding how quarantine measures in Hong Kong were effective in limiting community spread can provide us with valuable insights into how to suppress an outbreak. However, challenges exist in evaluating the effects of quarantine on COVID-19 transmission dynamics in Hong Kong due to the fact that the effects of border control have to be also taken into account. I showed how the effects of intervention measures were estimated using a meta-population model. International Forum on Data Science Approaches to the COVID-19 Pandemic [Online] Date and time: 28 and 29 May 2020 (Thursday and Friday), 9:00am – 12:00nn https://www.sdsc.cityu.edu.hk/news-events/events Prevention of COVID-19 after the Relaxation of Control Measures (10:50 – 11:10am) Dr Sean YUAN (Assistant Professor, Department of Biomedical Sciences, CityU)   Had a great time with many mosquito borne disease expert from all over the world in Taiwan. My student Mesfin and I were presenting our latest research results during poster exhibition session at National Health Research Institutes on 25 Nov.  My great experience to attend this wonderful meeting on Sep 28, where I found many interesting talks and met many old and new friends from all over the world. Really enjoy the foods and the night scenes there. Gld to meet my old boss Prof. Riley and his current group members from Imperial college London.
Dr. Yuan gave a talk with title "Effective control of Dengue fever – Predicting the climate impacts on the risk of dengue fever and mosquitoes in Hong Kong" (登革熱科學防疫 – 預測氣候對香港登革熱與病媒蚊風險的影響) in Foshan, Guangdong. Thanks for the invitation from Guangdong CDC. Having a nice Malaysian dinner to celebrate the achievement from our TA Kathleen, who will go to Harvard to study Biomedical Informatics. Can't wait to see a new fabulous scientist in the future. Congratulations!
