Italy develops vaccine candidate that neutralizes SARS-CoV-2 in mice

As the world grapples with the coronavirus disease (COVID-19), scientists race to develop treatments and vaccines to combat the viral infection. Though many ongoing trials show promise in fighting the novel coronavirus, Italian researchers claim they have developed a vaccine that can neutralize severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in animal cells.

No evidence COVID-19 is spread by fecal-oral transmission

A new study published on the preprint server medRxiv* in May 2020 shows that in patients who test positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in pharyngeal and fecal samples, the virus persists longer in the fecal samples than in the pharyngeal samples. However, fecal-oral transmission does not appear to occur.

Human neutralizing antibody pair blocks COVID-19-ACE2 binding

With the ongoing COVID-19 pandemic carving its deadly path across the world, and no end in sight in the immediate future, researchers are working furiously to bring out an effective therapeutic drug or vaccine that will stop the virus in its tracks.

COVID-19 could accelerate activation of dormant tuberculosis (TB)

The ongoing COVID-19 pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has thrown much of the world into disarray, with over 4 million people reported infected and well over 282,000 deaths. A new study published on the preprint server bioRxiv in May 2020 suggests that the long-term impact of the virus could include activation of dormant bacterial infections like tuberculosis (TB).

Neutralizing SARS-CoV-2 via S protein

A new study published on the preprint server bioRxiv* in May 2020 reports on a method to block severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by destroying its main spike protein, which is responsible for attachment to the host cell membrane.

Low-molecular-weight drugs could help against COVID-19 says study

Chinese researchers have worked on using existing low molecular weight drugs to treat severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that causes COVID-19 disease.

Reproduction number of COVID-19 and how it relates to public health measures

A new study published on the preprint server medRxiv in May 2020 reports the use of a dynamic SEIR model to identify variations in the reproductive number of SARS-CoV-2 over time, using machine learning techniques. This could help to model and predict the outcomes of various public health solutions.

Internet search patterns important in tracing and predicting COVID-19 spread

A new study published on the preprint server medRxiv in May 2020 has identified a link between Internet search patterns and local disease progression for COVID-19. It recommends the use of search data to track and predict COVID-19 spread as a complementary method to established public health surveillance methods.

Reproduction number and herd immunity in COVID-19

A new modeling study published on the preprint server medRxiv* in May 2020 hypothesizes that the asymptomatic cases in the ongoing pandemic in Japan may far outnumber the symptomatic infections by several orders of magnitude. This has implications for future predictions and public health policies.

Study demonstrates dynamic and broad-scale immune alterations in COVID-19 patient

A new case report released on the preprint server medRxiv* provides a detailed longitudinal analysis of the immune response associated with a fatal case of coronavirus disease (COVID-19). It highlights the need for addressing the source of hyper inflammation in the treatment approach.

Study shows COVID-19 vulnerability is highly dependent on host genetic architecture

A new US study available on the preprint server medRxiv reveals certain genetic variations that are associated with infection susceptibility and diverse clinical presentation of coronavirus disease (COVID-19) – including asymptomatic cases and severe forms of the disease in younger patients.

ACE inhibitors should not be discontinued over fears about COVID-19, say researchers

Researchers in Europe have found no evidence to support previous reports that the use of drugs that target the renin-angiotensin-aldosterone system (RAAS) increases susceptibility to coronavirus disease 2019 (COVID-19). The research is published in the European Heart Journal.

Understanding the ability of COVID-19 virus to infect pets and livestock

A new paper identifies the critical need for research on the ability of the COVID-19 virus to infect certain animal species, the transmissibility of infection between humans and those animals, and the impact infection could have on food security and the economy.
