Meteorological impact on the COVID-19 pandemic: A study across eight severely affected regions in South America.

ABSTRACT: The role of meteorological factors in the transmission of the COVID-19 still needs to be determined. In this study, the daily new cases of the eight severely affected regions in four countries of South America and their corresponding meteorological data (average temperature, maximum temperature, minimum temperature, average wind speed, visibility, absolute humidity) were collected. Daily number of confirmed and incubative cases, as well as time-dependent reproductive number (R_t) was calculated to indicate the transmission of the diseases in the population. Spearman's correlation coefficients were assessed to show the correlation between meteorological factors and daily confirmed cases, daily incubative cases, as well as Rt. In particular, the results showed that there was a highly significant correlation between daily incubative cases and absolute humidity throughout the selected regions. Multiple linear regression model further confirmed the negative correlation between absolute humidity and incubative cases. The absolute humidity is predicted to show a decreasing trend in the coming months from the meteorological data of recent three years. Our results suggest the necessity of continuous controlling policy in these areas and some other complementary strategies to mitigate the contagious rate of the COVID-19.

Project description:BackgroundThe COVID-19 pandemic has affected medical practice in fields not related to the infection. Neurogastroenterology is a subspecialty of gastroenterology focused on motility and functional gastrointestinal disorders, including consultations, and conducting procedures (eg, endoscopies, manometries/pH-monitoring).AimThe aim of this study was to determine the impact of COVID-19 on Neurogastroenterology in Latin America.MethodsMembers of the Latin American Society of Neurogastroenterology were invited by e-mail and social networks to participate in an online anonymous survey. It included 24 questions on demographics, clinical practice and procedure characteristics, impact of the pandemic, Telemedicine, and involvement in COVID-19 patient care.ResultsSixty-one members mainly from Colombia, Mexico, and Brazil answered the survey. All reported a negative impact on their practice (88.6%: a 61% to 100% decrease), mainly in office consultations and elective endoscopies. Interestingly, emergency endoscopies decreased by 33.3%, while only 4% stopped performing manometries/pH-monitoring. The main reasons were patients' fear for consulting, country's lockdown, and physician's decision to prevent infection spread. Telemedicine was implemented by 83% but only 64.7% were being remunerated. Almost 46% had to reduce salaries and working hours of their personnel. Fifty-nine percent had colleagues diagnosed with COVID-19, 24.6% were involved in these patients' care, and 11.5% were mobilized to COVID-19 wards. There were country differences: Colombia, lockdown (P=0.001); Mexico, COVID-19 patient-care (P=0.053); Mexico/Colombia, working in COVID-19 wards, (P=0.012); Brazil, less common elective procedures' ban (P=0.012) and Telemedicine/reimbursement (P=0.034).ConclusionsThe COVID-19 pandemic has negatively impacted the practice and wellness of Neurogastroenterologists in Latin America. Guidelines to resume activities and policies for Telemedicine practice and reimbursement are warranted.
