Transmissible. it s not spreading wildly. is there really a cause for concern? sure, we keep an eye on it, but there isn t a sense of panic here. should there be? no, there should not be a panic based on what we know about monkey pox because monkey pox has a lot more direct contact transmission, whether it s fluids, there is sexual transmission associated with it. you can get it from sheets and towels, but it doesn t have those respiratory droplets that make covid so contagious. you can, but you need a lot of them to get it. now, one little warning. we are starting to see as these cases increase people who do not have contact that are coming up positive. so that s why there s a big caution on this. normally we would see people coming out of africa, beguana, t ....

Frontiers | Impact of Prior Infection on Severe Acute Respiratory Syndrome Coronavirus 2 Transmission in Syrian Hamsters

Prior infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) provides protective immunity against reinfection. However, whether prior infection blocks SARS-CoV-2 transmission is not yet clear. Here, we evaluated the impact of prior infection on SARS-CoV-2 transmission in Syrian hamsters. Our results showed that prior infection significantly reduced SARS-CoV-2 replication in Syrian hamsters, but sterilizing immunity was not achieved. Prior infection blocked the airborne transmission of SARS-CoV-2 from previously infected Syrian hamsters to uninfected and previously infected Syrian hamsters and substantially reduced the efficiency of direct contact transmission between previously infected Syrian hamsters, but had limited impact on SARS-CoV-2 transmission from previously infected Syrian hamsters to uninfected Syrian hamsters via direct contact in the early course of infection. Human reinfection and SARS-CoV-2 transmission between a previously infected population and a ....

Antimicrobial Nanotechnology Solution for COVID-Free Surfaces

UK-based Cicada has launched a long-lasting antimicrobial solution to remove COVID on surfaces. The company was established as a subsidiary of an automotive industry specialist Duracare to create safe and COVID-free areas with nanotechnology.
Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) spreads when a person touches contaminated surfaces then directly touches their mouth, nose, or eyes. More than 68 million people have been infected worldwide at the time of writing.
Virus droplets contaminate surfaces for several days, with routine cleaning and disinfecting required.
Many commercial surface disinfectant kills the viruses but does not protect the surface from future contamination. This leads to viruses returning once the infected people come back to the area (Laister, 2020). Cicada has partnered with Signo NanoCare UK Ltd to develop virus-resistant nano-coating solutions. ....
