ABSTRACT
Since the COVID -19 epidemic has nearly brought about global catastrophe, every chance to make things better must be considered. One such technique for improvement is airborne decontamination. Researching this method's efficacy in the pandemic is vital since it can be used for surface cleaning of bigger areas. There are numerous instances of using drones to disinfect areas affected by epidemics, but best practices and factors affecting effectiveness have not yet been found. The adaptable uses of agricultural drones are evident from reports about utilizing drones for disinfection during a pandemic. The authors of this study calculated the potential amount of disinfectant fluid per unit area using various parameters for fly speed, flight altitude, and flow rate. As a result, by adjusting the settings, a range of disinfectant concentrations per unit area can be provided. Even though the results create a lot of new queries, they can be used to determine appropriate flying characteristics based on various disinfection liquids. © 2022 IEEE.
ABSTRACT
The expanded use of the Masi ventilators to more regions of Peru is important, particularly for regions located at high altitudes, due to the ventilatory support latent need, which also represents a challenge in the calibration and the adjustment of metrological parameters to ensure its correct performance. In a previous study, in Puno city at 3800 m.a.s.l., it was found an error above 15.0% (minimum tolerance) in the tidal volume, for which a negative correction of 25.0% was applied. In the present study, a Masi ventilator was transported to Chachapoyas city, at an altitude of 2400 m.a.s.l. to continue evaluating the effect of altitude on the parameters of the device. Once there, ventilators were acclimated and calibrated. Tidal volume, inspiration-expiration ratio (LE), positive endexpiratory pressure (PEEP), peak inspiratory flow (PIF) and peak inspiratory pressure (PIP) were tested, and the maximum percentages errors presented were 13.5% and 13.9% in the tidal volume and the PIF, respectively. For that reason, although errors were under 15.0%, an update of the software of Masi was needed, applying a negative correction of 14.0%. Then, the parameters were tested again obtaining results with errors below 6.0% and 8.0% in volume controlled an pressure controlled ventilation modes, respectively. These results allowed the use of the Masi ventilator at ICU area. Finally, a software update for the Masi ventilator is performed by applying a linear equation that relates altitudes and percentage errors tested.
ABSTRACT
B Introduction: b The severity of COVID-19 may be affected by environmental factors. While considering the altitude level, we found that it had a non-linear relationship with 28-day mortality (p=0.001, odds ratios for altitudes 75, 125, 400, and 600 m.a.s.l were: 0.96, 1.04, 0.49, and 0.51, respectively).

ABSTRACT
B Introduction: b Better delineation of COVID-19 presentations in different climatological conditions might assist with prompt diagnosis and isolation of patients. When adjusted for baseline differences, at lower latitudes (< 30°) patients presented less commonly with gastrointestinal symptoms (p< 0.001, odds ratios for latitudes 15°, 25°, and 30°: 0.32, 0.81, and 0.98, respectively).
