Scientists develop a smartwatch-based device for early detection of COVID-19

Scientists have developed a wearable device that can detect the early onset of COVID-19 in real-time by analyzing the aberrant changes in physiological parameters caused by SARS-CoV-2 infection.

How often does SARS-CoV-2 infect alongside another viruses?

Researchers have been exploring data from COVID-19 patients tested at hospitals or clinics that also look for evidence of other diseases.

Using metal nanoparticles to fight SARS-CoV-2

A recent review article looks at the potential of nanotechnology in fighting severe acute respiratory syndrome 2 (SARS-CoV-2), with several possibilities of strategies in therapeutics, vaccines, and prevention.

Relaxation of COVID-19 restrictions led to the reemergence of seasonal respiratory viruses in Houston

A Houston Methodist study showed a rapid return of seasonal respiratory viruses after COVID-19 restrictions were relaxed in Texas, demonstrating the effectiveness of masking, distancing and other precautionary measures at stopping the spread of many respiratory illnesses, not just COVID-19.

Discovery of a broad-spectrum antiviral activity in self-assembling immunostimulatory duplex RNAs

A new study, published on the bioRxiv* preprint server, has discovered a class of new immunostimulatory RNAs while studying influenza infection-associated host genes in human lung epithelial cells using small interfering RNAs (siRNAs). Scientists revealed that these short duplex RNAs could induce type I and type III interferons (IFN-I/III) in a wide variety of cells.

Potential COVID-19 nasal spray vaccine shows promise in mice

A single sniff may one day be all it takes to immunize yourself against COVID-19.

15 Nov 2021

Influenza and COVID vaccines can be co-administered in older adults without causing severe side effects

Researchers evaluate the safety and immunogenicity of an influenza vaccine and mRNA-based COVID-19 vaccine that were administered concomitantly.

New genetic epidemiology tool provides detailed information about viruses, coinfections

With mask wearing and social distancing on the decline and the cold and flu season upon us, researchers have developed a viral panel that enables the simultaneous testing for SARS-CoV-2 along with numerous common respiratory viruses, that tells us whether other viruses also are at play in patients hard hit by COVID.

Do weather and climate determine where COVID-19 occurs?

A new study provides information on the associations between weather parameters and seasonal coronavirus cases.

Structure of human-infecting canine coronavirus HuPn-2018 spike glycoprotein

As CCoV-HuPn-2018 has been recently isolated in a child's respiratory swab, researchers from the University Of Washington have been examining the structure of the virus.

Identification of long COVID patients using big data

A new preprint exploits big data to come up with some answers as to the incidence, treatment, and impact on healthcare systems of long covid.

Fluorescent system reveals how viruses produced during RSV infection change shape

Respiratory syncytial virus, more commonly known as RSV, is a highly contagious respiratory virus that can be very serious and even fatal for young children and the elderly.

Non-pharmaceutical interventions effectively reduce COVID case burden in the United States

A new study analyzes the impact of non-pharmaceutical interventions in the United States against SARS-CoV-2 transmission.

Dynamics of innate immune responses decide COVID-19 severity in genetically diverse mice

In a recently published article on the bioRxiv* preprint server, scientists from the USA and UK have described the significance of early inflammatory signaling pathways in determining the severity of coronavirus disease 2019 (COVID-19).

21 Sep 2021

As COVID restrictions were removed, Texas saw an increase in seasonal respiratory virus infections

Like many US states, Texas introduced many different measures to reduce the transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), such as masking, social distancing, and the closure of public services and businesses likely to aid the spread of disease.

Nanoparticles-assisted delivery of antiviral-siRNA for treatment of COVID-19

A review aimed to determine the potential of siRNA as a potential COVID-19 treatment by reviewing the currently available literature.

Early implementation of COVID-19 shutdowns saved thousands of lives in St. Louis area

In March 2020, not long after the first cases of COVID-19 were reported locally, health officials in the city of St. Louis and St. Louis County issued emergency public health orders intended to reduce interactions between people and slow the transmission of the novel respiratory virus.

Researchers develop adult lung organoids that represent all cell types

Since the COVID-19 pandemic reached the United States in early 2020, scientists have struggled to find laboratory models of SARS-CoV-2 infection, the respiratory virus that causes COVID-19. Animal models fell short; attempts to grow adult human lungs have historically failed because not all of the cell types survived.
