Symptomatic COVID-19 in University Students: A School-Wide Web-Based Questionnaire Survey during the Omicron Variant Outbreak

Aim: To detect risk and preventive factors associated with the Omicron variant infection in university students, a combination of a web-based survey and multivariate logistic regression analysis was introduced as the front-line initiatives by the school health practitioners. Design: Questionnaire survey. Methods: The school-wide web-based questionnaire survey was conducted among our university students as a part of the annual health check-up in April, 2023. The positive outcome was confined to the first symptomatic COVID-19 onset during the Omicron variant outbreak. Results: In this self-administered survey, risk or protective associations were merely estimated statistically in university students (n = 5406). In measured factors, karaoke and club/group activities could maintain the statistical significance in adjusted odds ratios (ORs) as relative risk factors, and science course, measles/ rubella (MR) vaccination, and COVID-19 vaccination remained as relative protective factors in adjusted OR analyses. Club/group activities with member gathering and karaoke sing-along sessions in university students may frequently have WHO’s three Cs. These risk factors are still important topics for the infection control of COVID-19 in university students. Together with some recent reports from other researchers, the significant protective role of MR vaccine in our survey warrants further clinical investigation. If the breakthrough infection continuously constitutes the majority of infection, real data in test-negative case-control or web-based questionnaire design continue to be important for statistical analysis to determine the minimal requirement of our strategies which may be equivalent to or replace COVID-19 vaccines.

COVID-19 Coronavirus: Is Infection along with <i>Mycoplasma</i>or Other Bacteria Linked to Progression to a Lethal Outcome?

Most patients with COVID-19 disease caused by the SARS-CoV-2 virus recover from this infection, but a significant fraction progress to a fatal outcome. As with some other RNA viruses, co-infection or activation of latent bacterial infections along with pre-existing health conditions in COVID-19 disease may be important in determining a fatal disease course. Mycoplasma spp. (M. pneumonaie, M. fermentans, etc.) have been routinely found as co-infections in a wide number of clinical conditions, and in some cases this has progressed to a fatal disease. Although preliminary, Mycoplasma pneumoniae has been identified in COVID-19 disease, and the severity of some signs and symptoms in progressive COVID-19 patients could be due, in part, to Mycoplasma or other bacterial infections. Moreover, the presence of pathogenic Mycoplasma species or other pathogenic bacteria in COVID-19 disease may confer a perfect storm of cytokine and hemodynamic dysfunction, autoimmune activation, mitochondrial dysfunction and other complications that together cannot be easily corrected in patients with pre-existing health conditions. The positive responses of only some COVID-19 patients to antibiotic and anti-malaria therapy could have been the result of suppression of Mycoplasma species and other bacterial co-infections in subsets of patients. Thus it may be useful to use molecular tests to determine the presence of pathogenic Mycoplasma species and other pathogenic bacteria that are commonly found in atypical pneumonia in all hospitalized COVID-19 patients, and when positive results are obtained, these patients should treated accordingly in order to improve clinical responses and patient outcomes.

The latest research progress of the Corona Virus Disease 2019 mutant strain"Omicron"

Coronavirus disease 2019(COVID-19)that broke out at the end of December 2019 has been raging for 3 years,bringing unpredictable harm to the physical and mental health of all mankind and global economic development.The new type of coronavirus pneumonia is a new type of respiratory infectious disease with a high incidence and fatality rate caused by SARS-CoV-2.Up to now,hundreds of millions of people have been infected with new coronary pneumonia worldwide,and millions of people have died.Due to the specificity of the new coronavirus itself and its high mutation rate,a series of different new coronavirus variants have appeared,which has caused the new crown pneumonia epidemic to repeat.Recently,the World Health Organization(WHO)announced a new variant"omicron"(omicron,B.1.1.529),and declared that the mutant strain may be highly infectious,antibody tolerant and highly resistant to vaccines.This article briefly reviews the latest research progress of the"omicron"variants.

COVID-19疫情对厦门市气象因素与流行性感冒发病关联分析的影响

目的目前尚不清楚新型冠状病毒感染(coronavirus disease 2019,COVID-19)疫情是否影响气象因素与流行性感冒(流感)的关联分析,本研究旨在探讨此问题及其影响特征,为今后精确评估气象因素对流感的风险效应提供依据。方法对厦门市气象因素和流感发病的每日数据分为三部分:全年期(2010年1月1日—2021年12月31日)、非COVID-19疫情期(2010年1月1日—2020年1月21日)和COVID-19疫情期(2020年1月22日—2021年12月31日),采用R 4.2.1软件通过分布滞后非线性模型(distributed lag nonlinear model,DLNM)进行气象因素与流感的关联分析。结果非COVID-19疫情期低(<42%)和高(>85%)相对湿度(relative humidity,RH)是流感的危险因素,高RH风险累计效应随滞后时间的增加而增加,随RH的增加而先增加后减弱,RH达到93%滞后14 d时最显著(RR=1.41)。COVID-19疫情期RHU<75%对流感的风险累计效应随RH的减少和滞后时间的增加而增加,RH为35%滞后14 d时最显著(RR=1.86×10^(6))。非COVID-19疫情期降水量(precipitation,PRE)处于25~75 mm对流感的风险累计效应先增加后减少,随滞后时间的增加而增加,滞后14 d,PRE达到40 mm时最显著(RR=1.49)。COVID-19疫情期PRE对流感的风险累计效应随PRE的增加而增加。COVID-19疫情期流感发病数的大幅下降严重影响气象因素与流感发病关联分析,致研究结果与全年期和非COVID-19疫情期差别较大;对全年期的研究结果影响较小。结论COVID-19疫情封控政策导致了厦门市COVID-19疫情期流感数大幅下降,从而显著影响了气象因素与流感发病关联分析客观性和科学性,但对长期多年度的分析结果影响有限。此外,极端天气例如RHU、PRE等对流感发病关联的分析也产生一定影响。

EPIDEM: A Mobile Application to Contain Coronavirus Disease 2019

With the spread of COVID-19 across the globe, almost 33 million people became sick and almost 1 million have died (WHO). The government of the Philippines, along with the government of other countries declared movement restrictions or lockdown in the attempt to contain the virus. This resulted in loss of job and economic breakdown. The Philippines, in particular, experienced the longest and strictest lockdown. As a down side, a lot of people have lost their jobs and the country is currently facing economic recession. With the aim of containing the virus to reopen the economy, a team of experts developed a mobile application called EPIDEM. The application is available for both Android and Apple smartphones. With the use of EPIDEM, lay people can monitor their infection risk for COVID-19 and isolate themselves or get themselves tested when infection risk is high. Users can also monitor the health risk of other people that they come in contact with, so they can decide if meeting them is safe or risky. Further, the application provides a monitoring map that shows the area that is safe from COVID-19 and area where a possible outbreak might occur. The monitoring map will be helpful to both lay people, so they would know the places to avoid and to government officials, so they can quickly respond to outbreak. The teams of developers are recommending the nationwide implementation of EPIDEM to help contain the COVID-19 outbreak in the country. The application is not a new strategy of containment. Instead, it’s a better wheel that utilizes advanced technology to execute the manual containment strategies that are already being implemented in the country.
