Latest Research on COVID-19 (SARS-CoV-2)

As the coronavirus SARS-CoV-2 spreads globally, we keep tracking the latest scientific findings and knowledge on the coronavirus and disease (COVID-19). We update this article regularly by searching contents of relevant journals and websites.

Projecting the transmission dynamics of SARS-CoV-2 through the postpandemic period

It is urgent to understand the future of severe acute respiratory syndrome–coronavirus 2 (SARS-CoV-2) transmission. Researchers used estimates of seasonality, immunity, and cross-immunity for betacoronaviruses OC43 and HKU1 from time series data from the USA to inform a model of SARS-CoV-2 transmission. They projected that recurrent wintertime outbreaks of SARS-CoV-2 will probably occur after the initial, most severe pandemic wave. Learn more

Structure of the RNA-dependent RNA polymerase from COVID-19 virus 

The RNA-dependent RNA polymerase (RdRp, also named nsp12) is the central component of coronaviral replication/transcription machinery and appears to be a primary target for the antiviral drug, remdesivir. Researchers reported the cryo-EM structure of COVID-19 virus full-length nsp12 in complex with cofactors nsp7 and nsp8 at 2.9-Å resolution. The structure provided a basis for the design of new antiviral therapeutics targeting viral RdRp. Learn more

Structural and Functional Basis of SARS-CoV-2 Entry by Using Human ACE2

In a new study published in Cell, researchers present the crystal structure of the C-terminal domain of SARS-CoV-2 (SARS-CoV-2-CTD) spike (S) protein in complex with human ACE2 (hACE2), which reveals a hACE2-binding mode similar overall to that observed for SARS-CoV. These findings shed light on the viral pathogenesis and provide important structural information regarding development of therapeutic countermeasures against the emerging virus. Learn more

Structure of Mpro from COVID-19 virus and discovery of its inhibitors

Researchers initiated a program of combined structure-assisted drug design, virtual drug screening and high-throughput screening to identify new drug leads that target the COVID-19 virus main protease (Mpro). Their results demonstrate the efficacy of this screening strategy, which can lead to the rapid discovery of drug leads with clinical potential in response to new infectious diseases for which no specific drugs or vaccines are available.

Effective containment explains subexponential growth in recent confirmed COVID-19 cases in China 

Researchers introduced a parsimonious model that captures both, quarantine of symptomatic infected individuals as well as population-wide isolation practices in response to containment policies or behavioral changes and show that the model captures the observed growth behavior accurately. The insights provided here may aid the careful implementation of containment strategies for ongoing secondary outbreaks of COVID-19 or similar future outbreaks of other emergent infectious diseases.

Susceptibility of ferrets, cats, dogs, and other domesticated animals to SARS–coronavirus 2 

Researchers investigated the susceptibility of ferrets and animals in close contact with humans to SARS-CoV-2. They found that SARS-CoV-2 replicates poorly in dogs, pigs, chickens, and ducks, but ferrets and cats are permissive to infection. They found experimentally that cats are susceptible to airborne infection. Their study provides important insights into the animal models for SARS-CoV-2 and animal management for COVID-19 control.

An orally bioavailable broad-spectrum antiviral inhibits SARS-CoV-2 in human airway epithelial cell cultures and multiple coronaviruses in mice

A new article published in Science showed that in mice infected with SARS-CoV or MERS-CoV, both prophylactic and therapeutic administration of EIDD-2801, an orally bioavailable NHC-prodrug (β-D-N4-hydroxycytidine-5′-isopropyl ester), improved pulmonary function, and reduced virus titer and body weight loss. The potency of NHC/EIDD-2801 against multiple coronaviruses and oral bioavailability highlight its potential utility as an effective antiviral against SARS-CoV-2 and other future zoonotic coronaviruses.
