How covid-19 spreads is one of the most debated questions of the pandemic. Chris Baraniuk explains what the evidence tells us about airborne transmission of the virus 
Airborne infection with Covid-19? A historical look at a current controversy
Airborne transmission: Are CO2 monitors a long term solution or “pandemic hack?”
TLDR
CO2 monitors have emerged as a cost effective way to tell how well ventilated a space is and if they should be adopted more widely.
Frequent Occurrence of SARS-CoV-2 Transmission among Non-close Contacts Exposed to COVID-19 Patients
TLDR
The proportion and circumstances of individuals to whom SARS-CoV-2 was transmitted without close contact with the index patient in a nosocomial outbreak in a tertiary care hospital in Korea are evaluated.
COVID‐19 in children: I. Epidemiology, prevention and indirect impacts
TLDR
It is emphasised the responsibility of paediatricians to advocate on behalf of this vulnerable group to ensure the longer‐term effects of COVID‐19 public health responses on the health and wellbeing of children are fully considered.
Nosocomial Outbreak of COVID-19 in a Hematologic Ward
TLDR
Transmission of SARS-CoV-2 in the hematologic ward occurred rapidly in the multi-patient room and shared bathroom settings and there was a case of possible airborne transmission due to unexpected airflow.
Global Prevalence of Adaptive and Prolonged Infections’ Mutations in the Receptor-Binding Domain of the SARS-CoV-2 Spike Protein
TLDR
The global prevalence of so-called ‘adaptive mutations’ and ‘mutations identified in the prolonged infections’, in the receptor-binding domain of the spike (S) protein, is estimated using the available 984,769 SARS-CoV-2 nucleotide sequences on the NCBI database from the end of 2019 till 28 July 2021.
Brought to Light: How Ultraviolet Disinfection Can Prevent the Nosocomial Transmission of COVID-19 and Other Infectious Diseases
TLDR
This review considers how pathogens are transmitted in healthcare facilities, the mechanism of UV microbial inactivation and the documented activity of UV against clinical pathogens, including severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) as well as multidrug resistant organisms (MDROs) that are commonly transmitted in Healthcare facilities.
A Review of COVID-19 Modelling Strategies in Three Countries to Develop a Research Framework for Regional Areas
TLDR
A literature review was conducted to summarise knowledge about COVID-19 disease modelling in three countries to develop a robust research framework for the regional areas that are urban and rural health districts of New South Wales, Australia.
Long Term Immune Response Produced by the SputnikV Vaccine
TLDR
Interestingly, many peptides were recognized by immunized and convalescent serum antibodies and correspond to conserved regions in circulating variants of SARS-CoV-2.
The impact of heating, ventilation and air conditioning (HVAC) design features on the transmission of viruses, including SARS-CoV-2: an overview of reviews
Objective: Given possible airborne transmission of SARS-CoV-2, an overview of reviews was conducted to understand what is already known from the scientific literature about how virus transmission may
