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.

The Defense Department is taking action around the globe to keep our service members, civilian employees, contractors and their families safe during the COVID-19 pandemic, all while supporting our continued mission.
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.
Study: An interactive web-based dashboard to track COVID-19 in real time
In response to COVID-19 ongoing public health emergency, we developed an online interactive dashboard, hosted by the Center for Systems Science and Engineering (CSSE) at Johns Hopkins University, Baltimore, MD, USA, to visualise and track reported cases of coronavirus disease 2019 (COVID-19) in real time.
Study: Multiple SARS-CoV-2 variants escape neutralization by vaccine-induced humoral immunity
Numerous variants of SARS-CoV-2-harboring mutations in spike have arisen globally
mRNA vaccines elicit potent neutralizing activity against homologous pseudovirus
Study: SARS-CoV-2 immune evasion by variant B.1.427/B.1.429
SARS-CoV-2 entry is mediated by the spike (S) glycoprotein which contains the receptor-binding domain (RBD) and the N-terminal domain (NTD) as the two main targets of neutralizing antibodies (Abs). A novel variant of concern (VOC) named CAL.20C (B.1.427/B.1.429) was originally detected in California and is currently spreading throughout the US and 29 additional countries. It is unclear whether antibody responses to SARS-CoV-2 infection or to the prototypic Wuhan-1 isolate-based vaccines will be impacted by the three B.1.427/B.1.429 S mutations: S13I, W152C and L452R.
Long COVID (Post-Acute Sequelae of SARS CoV-2 infection, PASC)
Long COVID, or what doctors refer to as post-acute sequelae of COVID-19 (PASC), is a condition marked by the continuation of COVID-19 symptoms—or the emergence of new ones—after recovery from acute (or the initial phase of illness of) COVID-19.

Study: COVID-19 Can Kill Months After Infection
Long-haul COVID-19 patients face many health threats — including a higher chance of dying — up to 6 months after they catch the virus, according to a massive study published in the journal Nature.
4 Reasons Why Fake News is So Compelling
There’s nothing new about fake news. For as long as there has been news, there has been misinformation, both deliberate and unintentional.
