COVID-19 progression linked to B cell activation

The disease course of COVID-19 is diverse, ranging from asymptomatic to fatal respiratory failure. Scientists have been working to uncover the immunological reasons behind this heterogeneity. A recent study on B cells, published on the preprint server medRxiv in April 2020, shows that extrafollicular B cells could be a marker of severe infection in the early stages, predicting the need for earlier immunomodulatory therapy.

Loss of smell may be related to neuroinvasive propensity of SARS-CoV-2

The novel coronavirus has rapidly infected millions over the world in over 187 countries and territories, causing hundreds of thousands of deaths. One of the often-neglected and under-reported symptoms of the virus is the loss of the sense of smell or anosmia. Now, a new study out of Germany published on the preprint server medRxiv in April 2020 provides a quantified estimate of the magnitude of anosmia as a symptom of the coronavirus.

Uncovering immune cell reactions in COVID-19

A new study published on the preprint server medRxiv in April 2020 suggests that an overactive immune response is responsible for the more severe manifestations of the illness.

Asymptomatic carriers transmit SARS-CoV-2 with normal breathing

The coronavirus disease (COVID-19) first emerged in a seafood market in Wuhan City, Hubei Province, China, in December 2019. Since then, it has spread to 187 countries, infecting more than 3.58 million people. The novel coronavirus spreads rapidly partly due to asymptomatic carriers. Now a new study shows that asymptomatic carriers may transmit the virus by merely breathing.

Loss of smell should be listed as early symptom of COVID-19

Though the two common symptoms are cough and fever, recent studies and reports point to a loss of smell as a symptom early in the disease process. A team of researchers at the Technical University Dresden (TU Dresden) revealed that the sudden loss of smell is experienced by many patients infected with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Human endemic coronavirus reinfection possible after recovery

The novel coronavirus started spreading in December 2019, and since then, it has rippled across the globe, affecting 187 countries and territories, and infecting more than 3.18 million people. However, the behavior and mechanism of the virus, including whether it provides adaptive immunity, is still unclear. There have been reports of reinfection out of South Korea and Japan

Dead virus fragments are causing COVID-19 reinfection false positives

The coronavirus disease (COVID-19) has ravaged across the globe, infecting a staggering 3.5 million people, and taking over 251,000 lives. One of the most significant concerns in this global pandemic is the possibility of reinfection as previous reports in South Korea and Japan show people testing positive with the coronavirus again.

Analysis of India's battle with COVID-19

A new paper published on the preprint server medRxiv in April 2020 suggests, based on mathematical models, that premature removal of lockdown restrictions in India could be highly counterproductive, enhancing the secondary spread of COVID-19, pushing up the number of fatalities and prolonging the course of the pandemic in India.

Study reveals an unprecedented pace and openness in COVID-19 research

The early academic response to coronavirus disease (COVID-19) was specified by research aiming to define the disease, with prompt response from all scholarly publishing stakeholders and short manuscript turnaround times, shows a new study available on the medRxiv* preprint server.

MU researcher finds four antiviral drugs effective in inhibiting novel coronavirus

Now, a researcher at the University of Missouri has found that four antiviral drugs, including remdesivir, a drug originally developed to treat Ebola, are effective in inhibiting the replication of the coronavirus causing COVID-19.

New computer modeling systems to predict spread of SARS-CoV-2 virus

Joe Mihaljevic, mathematical epidemiologist and assistant professor in Northern Arizona University's School of Informatics, Computing, and Cyber Systems, is leading a new project to create computer modeling systems to predict outcomes of the spread of the SARS-CoV-2 virus, which causes COVID-19, across four northern Arizona counties--Coconino, Navajo, Apache and Mohave.

Study defines new starting points for therapy and vaccine research on coronavirus

The SARS coronavirus 2 (SARS-CoV-2) infects lung cells and is responsible for the COVID-19 pandemic. The viral spike protein mediates entry of the virus into host cells and harbors an unusual activation sequence.

Study reveals variable sites in novel coronavirus SARS-CoV-2

Understanding the varying aggressiveness of SARS-CoV-2 may provide valuable data to trace its spread across populations. In the study, published on the preprint server BioRxiv, the researchers traced amino acid variants that possess high frequency in Europe, particularly in Italy, one of the hardest-hit countries.
