"These studies are inconsistent and do not give clear evidence as to whether there is an association between the temperature, humidity, and virus transmission, and the global view seems to give a clearer conclusion; all the three studies that conducted analysis at the global level found an association between higher humidity, warmer temperatures, and lower transmission rate (10). However, climate-dependent epidemic modeling suggested that the absence of population immunity is a much stronger factor in viral transmission and that summer weather will not substantially limit the spread of the COVID-19 pandemic"

"This study reveals the leading role of airborne SARS-CoV-2 transmission and negligible role of fomite transmission in a poorly ventilated indoor environment, highlighting the need for more targeted interventions in such environments. The quanta generation rate of the index case differed by a factor of 1.8 on the two buses and transmission occurred in the afternoon of the same day, indicating a time-varying effective viral load within a short period of five hours."

"support the necessity to wear surgical masks during the COVID-19 pandemics; "

As the COVID-19 pandemic has developed, concern for invasive fungal infections in critically ill COVID-19 patients with acute respiratory distress syn… "bronchoalveolar lavage or serum is supported by expert groups in Europe pending further research [8]. Experience with empirical or directed use of antifungal agents in the setting of COVID-19 is required, particularly in regards to efficacy, duration of treatment and possible adverse drug reactions in the setting of hepatotoxicity (a not uncommon feature of severe COVID-19), renal compromise, renal dialysis, arrhythmias, and electrolyte imbalance. Drug interactions with concurrent critical care agents or new or proposed COVID-19 specific therapies may influence the choice of an antifungal agent."

"Mice are not susceptible to SARS-CoV-2 infection and are, therefore, not suitable as research models" "SARS-CoV-2 can persist differently according to the surface, from hours to days (SARS-CoV-2 viability varies from hours to days depending on the surface), but infection only occurs when touching mucus membranes after contact with these contaminated surfaces. SARS-CoV-2 can also persist in air droplets for an uncertain period of time that could be longer if the virus is attached to pollution particles. Wastewater and tap water could act as SARS-CoV-2 propagation tools since positive samples of SARS-CoV-2 have been found in water samples in different countries worldwide." "All SARS viruses could be inactivated within 30 min at 20 °C with more than 0.5 mg/L residual free chlorine or 2.19 mg/L residual chlorine dioxide remaining"

This study documents results of SARS-CoV-2 polymerase chain reaction (PCR) testing of environmental surfaces and personal protective equipment surrounding 3 COVID-19 patients in isolation rooms in a Singapore hospital.

2019 July/ "Aspergillus spp... survives well in air, dust, and moisture present in health-care facilities." "Other opportunistic fungi that have been occasionally linked with health-care associated infections are members of the order Mucorales (e.g., Rhizopus spp.) and miscellaneous moniliaceous molds (e.g., Fusarium spp. and Penicillium spp.)"

The purpose of this paper was to investigate the effects of viral kinetics and exhaled droplet size on indoor transmission dynamics of influenza infection. The target cell-limited model with delayed virus production was adopted to strengthen the inner mechanisms of virus infection on human epithelia …

Aerosol transmission reflects a modern understanding of aerosol science and allows physically appropriate explanation and intervention selection for infectious diseases.

The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) originated in Wuhan, China in late 2019, and its resulting coronavirus disease, COVID-19, was declared a pandemic by the World Health Organization on March 11, 2020. The rapid global ...
