Visibility, wind speed, and dew point temperature are important factors in SARS‐CoV‐2 transmissibility

Abstract

The aim of this study is to provide evidence for the influencing factors of severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) virus mutation by determining the impact of geographical and meteorological factors on SARS-CoV-2 transmission, and the different impacts of SARS-CoV-2 variant strains. From January 20 to March 10, 2020, we collected a number of daily confirmed new cases and meteorological factors in all cities and regions in China and Italy affected by the Alpha "variants of concern" (VOC). We also

Presentation Rates for Acute Pharyngitis in the Emergency Room Are Influenced by Extreme Weather Events

“…Interestingly, both extremely high and low mean wind speeds resulted in delayed, elevated risk for ERV. Studies on viral respiratory tract infections such as COVID‐19 and influenza have shown the risk‐increasing effects of low wind speed on viral transmission 34‐37 . Furthermore, 1 study in an American population found that low wind speeds during temperatures that allow for outdoor social gatherings increased COVID‐19 cases 36 .…”

“…Studies on viral respiratory tract infections such as COVID-19 and influenza have shown the risk-increasing effects of low wind speed on viral transmission. [34][35][36][37] Furthermore, 1 study in an American population found that low wind speeds during temperatures that allow for outdoor social gatherings increased COVID-19 cases. 36 The authors discuss the possible lack of viral particle dispersion during low wind speeds as a possible explanation.…”

Performance comparison of 100Gbps upstream coherent passive optical network

“…The standardization of 25G-Ethernet PON (EPON) was completed in June 2020 by the IEEE 802.3ca Task Force based on 25 Gbps wavelengths in a multi-lane configuration. For the future PON systems, more than 50 Gb/s/λ of PON are being reported [6][7][8][9][10]. A 50 Gbps EPON system with a 25 Gbps multilane configuration achieves a loss budget of 29 dB, which is the same as 10G-EPON.…”
