A Preventive and Control Strategy for COVID-19 Infection: An Experience From a Third-Tier Chinese City.

COVID-19 is a rapidly spreading infectious disease that has led to a global pandemic. This study describes a novel strategy for preventing and controlling COVID-19 infection in the third-tier city of Liaocheng, China. The prevention and control measurements included city-wide orders to close workspaces, sanitize essential workspaces, quarantine individuals with a travel history to an epidemic area, and issue emergency medical responses to quarantine and treat COVID-19 patients using all necessary technologies, personnel, and resources. As a result, there were only 38 diagnosed COVID-19 cases in Liaocheng since the pandemic began in China in late 2019, including in the metropolitan area and six suburban counties, accounting for more than 6.39 millions residents living in a 8,715 km2 area. There was no COVID-19-related fatality and no healthcare professional inter-transmission as of June 25, 2020. The strategies of this third-tier Chinese city provide useful insights into approaches to prevent and control COVID-19 spread in other Chinese cities and countries.

Teat papillomatosis in dairy herds: First detection of bovine papillomavirus type 10 in China.

Teat papillomatosis is one important infectious disease affecting cattle health and results in significant economic losses especially in the dairy industry. Although there is a large number of commercial cattle herds in China, limited information is available for molecular epidemiological investigation of bovine papillomaviruses (BPVs). In October 2017, an outbreak of teat papillomatosis occurred in the Shandong Province of China. Samples were collected and diagnosed with PCR, and 3 full-length viral genomes were amplified from tissue samples collected from 3 outbreak farms. Analysis results revealed that the outbreak was associated with BPV type 10. This is the first report of BPV-10 infection in China and will contribute to the molecular epidemiological study of the disease.

Coinfection of a lingual lesion with bovine papular stomatitis virus and bovine papillomavirus.

To date, there have been no reports of coinfection with bovine papular stomatitis virus (BPSV) and bovine papillomavirus (BPV) in the same lesion. In the present study, one lingual papilloma-like sample was collected at an abattoir from the tongue of a 31-month-old Japanese black cow. Coinfection with BPSV and BPV was confirmed by histopathology, immunohistochemistry, PCR and RT-PCR. The evidence for coinfection with BPSV and BPV in the same lesion and an association of BPV with lingual papillomatosis will contribute to future epidemiological studies of these two viruses.

A comparison of sleeping problems in school-age children between rural and urban communities in China.

AIM: To investigate differences in sleeping behaviours in school-age children between urban and rural Chinese communities. METHODS: Children aged between 6 and 12 years old were selected from rural (n= 472) and urban communities (n= 576). Children's sleep habits questionnaire was completed by the parents to assess sleep patterns and sleep problems of the children. RESULTS: In the 6-8 and 9-12 years groups, the average sleep time in urban children was shorter than in the children from rural areas (9.0 +/- 1.1 vs. 11.3 +/- 1.1 h, and 9.2 +/- 1.0 vs. 10.2 +/- 0.9 h, respectively, all P < 0.01). The rate of abnormal sleep behaviour in the urban and rural cohort was 82.8 and 70.1%, respectively (P < 0.05). The prevalence of sleep delays in the 6- to 8-year-old children from urban areas was higher than in the rural areas (60.3 vs. 40.3%, P < 0.01). In the urban 9-12 years group, the rate of day-time sleepiness was higher than in the rural group (52.6 vs. 26.8%, P < 0.01), whereas the night waking rate was lower (43.8 vs. 58.6%, P < 0.01). Multivariate logistic regression analysis showed that the location of the residence, mother's age, parent's sleep habits and education levels predict the sleeping problems in these children. CONCLUSION: Children from urban communities appear to have sleeping problems than children from a rural setting. A parent's sleep habits, education levels and the location of children's residence have significant impact on the children's sleep behaviour and habits.
