“…Despite HK is one of the most densely populated area in the world, before 2022, the effects of restrictive measures imposed by HK government were very satisfactory in limiting the spread of pandemic, despite the virus mutations [19 , 20] , hence the fifth wave in HK offered a different perspective to evaluate intrinsic epidemiological parameters related to Omicron VOC because it developed from a rather unperturbed zero-covid environment.…”

“…The Hong Kong Special Administrative Region of the People's Republic of China (HK) recorded relatively few cases of coronavirus disease 2019 (COVID- 19), and especially if compared with other densely populated regions, due to the quick restrictive measures adopted at the beginning of the outbreak, which caused low local transmission rates with few or no local infections, as demonstrated by the mean effective reproductive number between January 23 rd , 2020 and May 12 th , 2021 [1,2]. As a result, from January 2020, HK had a total cumulative incidence of about 10000 positive tested cases thanks to an "elimination strategy" which supports the so called "Zero-COVID" regime, albeit it featured formally four different pandemic waves.…”

We present the evolution of time dependent reproduction number across the five different Hong Kong Special Administrative Region of the People's Republic of China (HK) epidemic waves from January, 2020, to March, 2022. We provide reliable estimation of reproduction number of Omicron variant of concern (VOC) by analysing data related to fifth wave to determine its peculiar characteristics with respect to the other VOCs. HK could be considered as the optimal model for the calculation of the dynamics of Omicron VOC transmission in an environment representative of the fully populated cities of the Asian Pacific coast. On the basis of Rt calculated for Omicron VOC in our work, researchers could refine provisional data for the current outbreak which is affecting China

“…The impact of the Covid-19 pandemic has forced all training activities to be adjusted. The government has banned face-to-face activities for a certain period of time, because it has the potential to transmit the virus (Lou et al, 2022); (Ali, 2020). Likewise, archery training activities, must make a lot of restrictions and adjustments.…”

This study aims to determine (1) the constraints of trainers in managing archery training in Pati Regency during the Covid-19 pandemic. (2) The trainer's efforts in managing the archery training of Pati Regency during the Covid-19 pandemic. This research is a mixed method (mixed methods). The population in this study were 3 coaches and 16 athletes in Pati Regency. The samples used are 3 coaches and 16 athletes based on total sampling. The instruments in this study, namely interviews and questionnaires. Data analysis used descriptive qualitative and quantitative. The results showed that (1) the trainer's obstacle in managing archery training in Pati Regency during the Covid-19 pandemic was adaptation related to the use of available technology to support the training process a form of archery training carried out during the Covid-19 pandemic, the coach used online and offline media (face to face). The problem that occurs is the availability of quotas that require a fairly high price to facilitate the need for online training. The quota purchased for internet needs is increasing and many parents are not ready to increase the budget in providing internet networks. (2) The efforts of the trainers in managing the archery training in Pati Regency during the Covid-19 pandemic were quite good. Based on the results, it shows that the indicator of the exercise schedule is the highest at 3.00 in the good category, while the lowest indicator is the exercise program at 2.53.
