ABSTRACT
Objective To assess the risk of public health emergencies, both the indigenous ones and the imported ones, which might occur in the mainland of China in April 2022. Methods An internet based expert counsel was conducted to analyze the surveillance data of public health emergencies and priority communicable diseases in China reported through different channels, and the experts in all provincial centers for disease control and prevention attended this video conference. Results It is expected that number of domestically reported public health emergency events other than COVID-19 in April would remain unchanged from March. The risk of domestic COVID-19 outbreaks caused by the indigenous transmission and the foreign importation is high, making it more difficult to prevent and control the epidemic. Local governments need to strengthen epidemic prevention and control in accordance with national requirements and hold the bottom line of no large-scale rebound of the epidemic. The number of pertussis cases will maintain rising trend due to the improvement of laboratory testing technology, the weakening of vaccine protection and the strengthening of surveillance in some districts. Conclusion Special attention should be paid to COVID-19. General attentions should be paid to pertussis.
ABSTRACT
BACKGROUD: The association between underlying comorbidities and cardiac injury and the prognosis in coronavirus disease 2019 (COVID-19) patients was assessed in this study. HYPOTHESIS: The underlying comorbidities and cardiac injury may be associated with the prognosis in COVID-19 patients. METHODS: A systematic search was conducted in PubMed, EMBASE, Web of science, and The Cochrane library from December 2019 to July 2020. The odds ratio (OR) and 95% confidence intervals (95% CI) were used to estimate the probability of comorbidities and cardiac injury in COVID-19 patients with or without severe type, or in survivors vs nonsurvivors of COVID-19 patients. RESULTS: A total of 124 studies were included in this analysis. A higher risk for severity was observed in COVID-19 patients with comorbidities. The pooled result in patients with hypertension (OR 2.57, 95% CI: 2.12-3.11), diabetes (OR 2.54, 95% CI: 1.89-3.41), cardiovascular diseases (OR 3.86, 95% CI: 2.70-5.52), chronic obstractive pulmonary disease (OR 2.71, 95% CI: 1.98-3.70), chronic kidney disease (OR 2.20, 95% CI: 1.27-3.80), and cancer (OR 2.42, 95% CI: 1.81-3.22) respectively. All the comorbidities presented a higher risk of mortality. Moreover, the prevalence of acute cardiac injury is higher in severe group than in nonsevere group, and acute cardiac injury is associated with an increased risk for in-hospital mortality. CONCLUSION: Comorbidities and acute cardiac injury are closely associated with poor prognosis in COVID-19 patients. It is necessary to continuously monitor related clinical indicators of organs injury and concern comorbidities in COVID-19 patients.
