    Coronavirus latest: has the outbreak in China peaked? Scientists are concerned about a new virus that has infected tens of thousands of people and killed more than 1,000. The virus, which emerged in the Chinese city of Wuhan in December, is a coronavirus and belongs to the same family as the pathogen that causes severe acute respiratory syndrome, or SARS. It causes a respiratory illness called COVID-19, which can spread from person to person. Here’s the latest news on the outbreak. 18 February 11:00 GMT — Has the outbreak peaked in China? A study of nearly 45,000 confirmed COVID-19 infections in China suggests that the outbreak might already have reached its climax . The report, from the country’s Centre for Disease Control and Prevention, says that the day with the highest number of new infections — known as the peak — occurred around the end of January; since then, the number of new confirmed cases per day has declined. However, the number of new suspected cases and those cases diagnosed by physicians using chest images, known as clinically diagnosed cases, stayed at roughly the same levels each day over the study period, which ended on 11 February. The latest data on coronavirus infections in China appears to show a decline in new cases, said Tedros Adhanom Ghebreyesus, the World Health Organization’s (WHO) director-general, at a press briefing on the same day. But he said the trend must be interpreted cautiously. “It’s too early to tell if this new reported decline will continue,” he said. “Every scenario is still on the table.” Raina MacIntyre, a physician and epidemiologist at the University of New South Wales in Sydney, Australia, agrees that data need to be considered with caution, but says the general trends are informative. The WHO’s reports also show a decline in new cases reported per day in China and worldwide, she says. But the extended holiday period in China that ended on 9 February means there might be another increase in new cases around 21 February, as people return to work. “Often with epidemics we see more than one peak,” says MacIntyre. Epidemiologists have been trying to estimate roughly when the outbreak will peak. Public-health officials want to know this so they can prepare hospitals and know when it will be safe to lift travel restrictions in Wuhan and several nearby cities. Some models suggest that the climax will happen any time now. Others say that it is months away and that the virus will infect millions — or, in one estimate, hundreds of millions — of people before then. This model assumes that many more people have been infected than the official counts, but that these people are asymptomatic or not ill enough to seek medical treatment.

    Perinatal Depression of Women Along with 2019 Novel Coronavirus Breakout in China Yan-Ting Wu,Chen Zhang,Han Liu,Chen-Chi Duan,Cheng Li,Jian-Xia Fan ... ... Date Written: February 17, 2020 Abstract Background On 20th Jan 2020, a new coronavirus epidemic with “human-to-human” transmission was officially announced, which inevitably caused public panic in China. Perinatal depression (PND) is one of the most common mental health problems. The purpose of this study is to explore the mental impact of COVID-19 outbreak on pregnant women. Methods A total of 4124 pregnant women during third trimester from 25 hospitals in 10 provinces were recruited in this cross-sectional study, from Jan/01 to Feb/09, 2020. Among them, 1285 pregnant women were assessed after Jan/20, and 2839 were assessed before that time point. The Edinburgh Postnatal Depression Scale (EPDS) was used to evaluate the maternal psychological situation. Prevalence of PND and anxiety were compared between two groups. Findings Pregnant women had higher scores in EPDS (7.7 vs 7.4, P=0.03) and anxiety subscale (3.4 vs 3.2, P=0.04), especially the highest score for thoughts of self-harm (P=0.005) after the declaration of COVID-19 epidemic. Awareness of COVID-19 significantly increased the prevalence of PND (26.0% vs 29.6%, P=0.02). The COVID-19 number of newly- confirmed, suspected infections, and death cases per day was positively associated with the prevalence of PND (P=0.003, 0.004, and 0.001, respectively). Pregnant women those who were underweight, full-time employed, middle income, age < 35 yrs, primiparous, less exercise, appropriate living area appeared to be more susceptible to the outbreak. Interpretation COVID-19 outbreak can increase the depressive risk of pregnant women, especially in the self-harm inclination, suggesting that psychological intervention is an urgent need for maternal population.

    Reverse Logistics Network Design for Effective Management of Medical Waste in Epidemic Outbreak: Insights from the Coronavirus Disease 2019 (COVID-19) in Wuhan 22 Pages Posted: 18 Feb 2020 Hao Yu University of Tromsø - The Arctic University of Norway Xu Sun University of Tromsø - The Arctic University of Norway Wei Deng Solvang University of Tromsø - The Arctic University of Norway Xu Zhao China Three Gorges University (CTGU) Date Written: February 14, 2020 Abstract The outbreak of an epidemic disease may impose significant treats on human being and may further lead to a global crisis. In order to effectively control epidemic spread, a responsive logistics service is of vital importance. Over the years, researches have been focused on the establishment and the operations of temporary logistics network for delivering medical service and allocating emergency resources. However, the research focus has not been given to the design of a temporary reverse logistics network for medical waste treatment in epidemic outbreak, which, if improperly treated, may accelerate disease spread and pose a significant risk on both medical staffs and patients. Therefore, this paper formulates a novel multi-objective multi-period mixed integer program for reverse logistics network design in epidemic outbreak, which aims at effective management of the exponentially increased medical waste and healthcare hazards within a very short period. The model is validated with a real-world case study based on the outbreak of the coronavirus disease 2019 (COVID-19) in Wuhan, China. Even through the uncertainty of the future tendency of the COVID-19 spread is very high at the time of this research, some general managerial implications can still be obtained based on quantitative analyses. Among other insights, the computational results suggest installing and operating temporary incinerators at proper locations may be an effective solution for managing the tremendous increase of medical waste during the COVID-19 outbreak in Wuhan.
