Study: Frequent neurologic manifestations and encephalopathy-associated morbidity in Covid-19 patients

Covid-19 can involve multiple organs including the nervous system. We sought to characterize the neurologic manifestations, their risk factors, and associated outcomes in hospitalized patients with Covid-19.

Study: Optical Biosensors for Virus Detection: Prospects for SARS-CoV-2/COVID-19

Optical biosensors have led to significant advancements in virus detection and imaging capabilities. Coupled with advanced instrumentation, they have enabled higher sensitivities while increasing the rate at which samples can be tested. These techniques can be developed into point-of-care (POC) diagnostics for viral detection and are promising alternatives to detect COVID-19.

Study: SARS-CoV-2 Transmission From People Without COVID-19 Symptoms

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the etiology of coronavirus disease 2019 (COVID-19), is readily transmitted person to person. Optimal control of COVID-19 depends on directing resources and health messaging to mitigation efforts that are most likely to prevent transmission, but the relative importance of such measures has been disputed.

Study: Comparative evaluation of 19 reverse transcription loop-mediated isothermal amplification assays for detection of SARS-CoV-2

Coronavirus disease 2019 (COVID-19) caused by SARS-CoV-2 has caused a global pandemics. To facilitate the detection of SARS-CoV-2 infection, various RT-LAMP assays using 19 sets of primers had been developed, but never been compared. 

Study: Lateral flow tests cannot rule out SARS- CoV-2 infection

Lateral flow devices for asymptomatic mass testing are proving controversial. At the heart of the matter is a flawed process, with the decision to implement society-wide “Moonshot” testing made before robust field evaluations of the tests were completed. Subsequent selective emphasis of unrealistic performance estimates has caused confusion. Little surprise we are now in a mess.

Study: Saliva is more sensitive than nasopharyngeal or nasal swabs for diagnosis of asymptomatic and mild COVID-19 infection

Acute coronavirus disease 2019 (COVID-19) is primarily diagnosed via reverse transcription-polymerase chain reaction (RT-PCR) detection of viral genetic material. However, considering the three primary modes of transmission of SARS-Cov-2 i.e., contact, droplet and aerosol routes, various types of samples have been suggested for the purpose of detection.

Study: Benefits of Mobile Contact Tracing on COVID-19: Tracing Capacity Perspectives

For effectively suppressing COVID-19’s spread, contact tracing has been widely used to identify, isolate, and follow-up with those who have come in close contact with an infected person (or “close contacts”). Traditionally, contact tracers in local health offices interview an infected person to identify visited places (or hotspots) and then check any close contacts. For the accurate recall of travel history, several countries including South Korea corroborate multiple data sources, such as cell location or credit card transactions.

Study: U.S. Navy’s Response to a Shipboard Coronavirus Outbreak: Considerations for a Medical Management Plan at Sea

The authors observe with interest the ongoing management of the 2019 coronavirus (COVID-19) pandemic and its impact on the U.S. Navy.

More young people are getting hospitalized as a ‘stickier,’ more infectious coronavirus strain becomes dominant

What used to be a mysterious new variant first detected in the UK is now the most dominant coronavirus strain in the US. And unlike the original strain of the novel coronavirus, the more contagious B.1.1.7 strain is hitting young people particularly hard.

Article: The tragedy of long COVID

Tens of thousands of people in the United States have lingering illness following COVID-19. In the US, we call them post-COVID “long haulers.” Currently, the condition they are suffering from is known as “long COVID,” although other names are being proposed.
