Author:Yongjian Zhu
Abstract:Background: Coronavirus disease 2019 (COVID-19) has become a severe public
health problem globally. Both epidemiological and laboratory studies have
shown that ambient temperature could affect the transmission and survival of
coronaviruses. This study aimed to determine whether the temperature is an
essential factor in the infection caused by this novel coronavirus.
Methods: Daily confirmed cases and meteorological factors in 122 cities were
collected between January 23, 2020, to February 29, 2020. A generalized
additive model (GAM) was applied to explore the nonlinear relationship between
mean temperature and COVID-19 confirmed cases. We also used a piecewise
linear regression to determine the relationship in detail.
Results: The exposure-response curves suggested that the relationship between
mean temperature and COVID-19 confirmed cases was approximately linear in

the range of less than 3 °C and became flat above 3 °C. When mean temperature
(lag0-14) was below 3 °C, each 1 °C rise was associated with a 4.861% (95% CI:
3.209-6.513) increase in the daily number of COVID-19 confirmed cases. These
findings were robust in our sensitivity analyses.
Conclusions: Our results indicate that mean temperature has a positive linear
relationship with the number of COVID-19 cases with a threshold of 3 °C. There
is no evidence supporting that case counts of COVID-19 could decline when the
weather becomes warmer, which provides useful implications for policymakers
and the public.

Author:ZHOU Ji-biao
Abstract: Confronting the major national epidemic, urban public transport (UPT) system has the dual responsibility of ensuring basic trip and blocking the spread of the epidemic. Facing to the epidemic caused by novel coronavirus pneumonia (COVID-19), UPT system should not only organize effective transport, but also reduce the risk of the spread of the epidemic. Metros and conventional buses are indispensable parts of UPT system, and they also play a very important role in them. Under the urgent outbreaking epidemic, the epidemic prevention strategy of UPT system needs to activate the emergency response mechanism and follow the basic principles of the regional classification prevention and control strategy. Not only guarantees people's rigid travel demand, but also it must block the spread of the epidemic, and reduce cross-infection caused by UPT. And finally, the COVID-19 is prevented and controlled by the prevention strategy. In addition to epidemic prevention measures such as body temperature detection, wearing masks, and hand washing and disinfection in the early stages of the epidemic, an unconventional and targeted combined epidemic prevention strategy should be adopted for UPT system in combination with local actual conditions and risk assessment levels, these are, on the one hand, (1) for the conventional buses system, the epidemic prevention strategies with recommendations were addressed, namely, a grid-based operation strategy, a demand-responsive operation strategy, and an emergency bus connection strategy. On the other hand, (2) for the urban rail transit system, the three-level combined epidemic prevention strategies with recommendations were also addressed, namely, a suspension of subway operations strategy, a compartment isolation epidemic prevention strategy, and a demand-response epidemic prevention strategy. The above-mentioned multiple combined epidemic prevention strategies of conventional buses and urban rail transit need to be dynamically adjusted according to the development of the epidemic situation, and the corresponding level of public transport emergency plan should be activated in time, and in practice, the passive defense and active prevention and control need to be combined, and finally, UPT system plays an important role in transportation and emergency-response during the epidemic period.

Abstract: Novel coronavirus pneumonia (COVID-19) spreads quickly. We need to have an accurate understanding of the cumulative confirmed count in various provinces in China. The static spatial distribution and dynamic evolution of the cumulative confirmed count in various provinces in China are revealed by using spatial statistical analysis. The data of the cumulative confirmed count from January 26th, 2020 to February 20th, 2020, from the outbreak to the control of the virus, is analyzed. The results show the cumulative confirmed count of each province in China has a positive spatial correlation before February 3th, a negative spatial correlation from February 3th to February 11th, and a random distribution in space after February 11th. Looking at the characteristics of local aggregation in different provinces, the high-low clustering occurs mainly in Hubei, while the low-high clustering mainly in provinces around Hubei. And provinces far from Hubei are low-low pattern. And the provinces with significant high-low clustering and low-high clustering gradually increase.

Abstract: Water turbidity is one of the most important parameters of inland lake water quality and an important influencing factor of water environment ecosystem. Wuhan City, a metropolis in central China, suffered a lot in the 2019 novel coronavirus pneumonia. During the period from January 25, 2020 to February 5, 2020, the Chinese central government decided to build two emergency hospitals, namely Huoshenshan and Leishenshan, to cope with the epidemic. In the process of hospital construction, dynamic monitoring of turbidity in the adjacent waters is helpful for epidemic prevention and government decision-making. Using Chinese high-resolution Haiyang-1C data, combined with high-frequency in-situ turbidity measurements, a turbidity model suitable for Wuhan waters was established (determinant coefficient: R2>0.85; root mean square error: RMSE<5.5 NTU). Through the analysis of the variations of turbidity at Zhiyin, Huangjia, and Zhushan lakes, we found that the variation trends of waters near and away from Huoshenshan or Leishenshan hospitals were similar, indicating that the constructions of the two hospitals didn’t affect the nearby waters. The variations of rainfalls at Wuhan might cause the decline of water turbidity. This study also shows that Chinese Haiyang-1C has the potential to retrieve turbidity in small inland waters.

Author:Andrew J. Stier
Abstract:The current outbreak of novel coronavirus disease 2019 (COVID-19) poses an
unprecedented global health and economic threat to interconnected human so_x0002_cieties. Until a vaccine is developed, strategies for controlling the outbreak rely
on aggressive social distancing. These measures largely disconnect the social
network fabric of human societies, especially in urban areas. Here, we estimate the growth rates and reproductive numbers of COVID-19 in US cities
from March 14th through March 19th to reveal a power-law scaling relationship to city population size. This means that COVID-19 is spreading faster on
average in larger cities with the additional implication that, in an uncontrolled
outbreak, larger fractions of the population are expected to become infected in
more populous urban areas. We discuss the implications of these observations
for controlling the COVID-19 outbreak, emphasizing the need to implement
more aggressive distancing policies in larger cities while also with preserving
socioeconomic activity.

Author:Biqing Chen
Abstract:The novel coronavirus (SARS-CoV-2/ 2019-nCoV) identified in Wuhan, China, in
December 2019 has caused great damage to public health and economy worldwide
with over 140,000 infected cases up to date. Previous research has suggested an
involvement of meteorological conditions in the spread of droplet-mediated viral
diseases, such as influenza. However, as for the recent novel coronavirus, few studies
have discussed systematically about the role of daily weather in the epidemic
transmission of the virus. Here, we examine the relationships of meteorological
variables with the severity of the outbreak on a worldwide scale. The confirmed case
counts, which indicates the severity of COVID-19 spread, and four meteorological
variables, i.e., air temperature, relative humidity, wind speed, and visibility, were
collected daily between January 20 and March 11 (52 days) for 430 cities and districts all over China, 21 cities/ provinces in Italy, 21 cities/ provinces in Japan, and 51 other
countries around the world. Four different time delays of weather (on the day, 3 days
ago, 7 days ago, and 14 days ago) as to the epidemic situation were taken for
modeling and we finally chose the weather two weeks ago to model against the daily
epidemic situation as its correlated with the outbreak best. Taken Chinese cities as a
discovery dataset, it was suggested that temperature, wind speed, and relative
humidity combined together could best predict the epidemic situation. The
meteorological model could well predict the outbreak around the world with a high
correlation (r2>0.6) with the real data. Using this model, we further predicted the
possible epidemic situation in the future 12 days in several high-latitude cities with
potential outbreak. This model could provide more information for government's
future decisions on COVID-19 outbreak control.

温度和纬度分析以预测COVID-19的潜在扩散和季节性 #4426_1

Abstract:A significant number of infectious diseases display seasonal patterns in their incidence, including
human coronaviruses. We hypothesize that SARS-CoV-2 does as well. To date, Coronavirus Disease
2019 (COVID-19), caused by SARS-CoV-2, has established significant community spread in cities
and regions only along a narrow east west distribution roughly along the 30-50 N” corridor at
consistently similar weather patterns (5-11OC and 47-79% humidity). There has been a lack of
significant community establishment in expected locations that are based only on population proximity
and extensive population interaction through travel. We have proposed a simplified model that shows
a zone at increased risk for COVID-19 spread. Using weather modeling, it may be possible to predict
the regions most likely to be at higher risk of significant community spread of COVID-19 in the
upcoming weeks, allowing for concentration of public health efforts on surveillance and containment.

季节性强迫对SARS-CoV-2大流行的潜在影响 #4145_1

Author:Richard A. Neher
Abstract:A novel coronavirus (SARS-CoV-2) first detected in Wuhan, China, has spread rapidly since December 2019, causing more than 80,000 confirmed infections and 2,700 fatalities (as of Feb 27, 2020). Imported cases and transmission clusters of various sizes have been reported globally suggesting a pandemic is likely. Here, we explore how seasonal variation in transmissibility could modulate a SARS-CoV-2 pandemic. Data from routine diagnostics show a strong and consistent seasonal variation of the four endemic coronaviruses (229E, HKU1, NL63, OC43) and we parameterize our model for SARS-CoV-2 using these data. The model allows for many subpopulations of different size with variable parameters. Simulations of different scenarios show that plausible parameters result in a small peak in early 2020 in temperate regions of the Northern Hemisphere and a larger peak in winter 2020/2021. Variation in transmission and migration rates can result in substantial variation in prevalence between regions. While the uncertainty in parameters is large, the scenarios we explore show that transient reductions in the incidence rate might be due to a combination of seasonal variation and infection control efforts but do not necessarily mean the epidemic is contained. Seasonal forcing on SARS-CoV-2 should thus be taken into account in the further monitoring of the global transmission. The likely aggregated effect of seasonal variation, infection control measures and transmission rate variation is a prolonged pandemic wave with lower prevalence at any given time, thereby providing a window of opportunity for better preparation of health care systems.
