Study suggests SARS-CoV-2 could affect aquatic wildlife

Study suggests SARS-CoV-2 could affect aquatic wildlife
Researchers have found that oxidative stress and neurotoxicity biomarkers increased in tadpoles exposed to synthetic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein peptides.
SARS-CoV-2, the causative pathogen of coronavirus disease 2019 (COVID-19), spreads mainly by the airborne transmission of virus droplets from an infected person. However, the virus can stay alive on various surfaces (also known as fomites ) for several days. Coming in contact with such contaminated surfaces can also cause virus transmission.
Environmental transmission of the virus can also occur through indirect contact with urine or stool of infected people. Studies around the globe have detected the presence of the virus s ribonucleic acid (RNA) in sewage and wastewater. Household waste from hospitals and large buildings can thus harbor the virus and its ecotoxicological effects are yet unknown. ....

Sustained immune response memory detected in recovered COVID-19 patients

Sustained immune response memory detected in recovered COVID-19 patients
Since the coronavirus disease 2019 (COVID-19) pandemic began, scientists have been keen to know if primary infection in recovered individuals yields long-lasting immunity against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes COVID-19.
A team of researchers at the University of Washington School of Medicine has found that people who had mild COVID-19 developed a multi-layered immune response against SARS-Cov-2. The researchers detected neutralizing antibodies against the virus for at least three months after recovering from the infection.
Specifically, the team found virus-specific memory B and T cells displaying anti-viral immunity. Memory B cells (MBCs) increase in number and express antibodies capable of neutralizing SARS-CoV-2. ....

Could wastewater surveillance help track SARS-COV-2 community outbreaks?

Could wastewater surveillance help track SARS-COV-2 community outbreaks?
Since it was first detected in Wuhan, China, in December 2019, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative pathogen of coronavirus disease 2019 (COVID-19), has infected over 73.37 million people and taken the lives of over 1.63 million worldwide.
As 2020 draws to a close, various national regulatory bodies have given the go-ahead on the innovative new mRNA vaccine candidate developed by Pfizer and BioNTech – including the UK, Canada and the USA. In the UK, targeted vaccinations are already being administered to the elderly, the immunocompromised and frontline healthcare workers.
While these are promising signs, the crisis is far from over. The complex logistics, financials and compliance-based issues of promoting herd immunity by vaccination at the national, not least global, level are yet to be fully ironed out. ....
