By Dr. Priyom Bose, Ph.D.Jul 12 2022Reviewed by Benedette Cuffari, M.Sc. Scientists have worked relentlessly to contain the coronavirus disease 2019 pandemic caused by the severe acute respiratory syndrome coronavirus 2 . To this end, several pharmaceutical and non-pharmaceutical strategies have been developed to prevent further transmission of SARS-CoV-2 and protect individuals from severe infection.
To date, most available studies have focused on the impact of travel restrictions on the early phase of the COVID-19 pandemic. Although some studies have shown that these restrictions significantly delayed viral transmission, others have contradicted these observations and instead reported that travel restrictions were inadequate to preventing global transmission of SARS-CoV-2.
In fact, several studies have successfully isolated viral genotypes circulating within a community by sequencing the SARS-CoV-2 genome from sewage samples. About the study A new Viruses study successfully detected SARS-CoV-2 variants in the wastewater of aircrafts. Herein, researchers obtained wastewater samples from two flights traveling from Addis Ababa, Ethiopia to Marseille, France.
Taken together, 12 passengers of the December 24, 2021 flight tested positive for SARS-CoV-2 by a lateral flow test. Genomic sequencing of 11 of these samples confirmed the presence of the Omicron variant. Although the wastewater tanks were thoroughly cleaned between flights, the possibility of contamination by traces of SARS-CoV-2 RNA in the blackwater tanks from previous flights cannot be entirely omitted. However, in this case, the high viral load cannot be the result of contamination and is strongly linked to viral excretion by onboard passengers or aircraft crew.

A broadly neutralizing antibody protects Syrian hamsters against SARS-CoV-2 Omicron challenge - Nature CommunicationsSARS-CoV-2 variants of concern such as the Omicron variant pose a challenge for vaccination and antibody immunotherapy. Here, Zhou et al. isolate a broadly neutralizing antibody (bNAb), named ZCB11, that protects Golden Syrian hamsters against Omicron. Applying CryoEM the authors show that ZCB11 heavy chain predominantly interacts with RBD in up confirmation, which interferes with ACE2 receptor binding.
