[Editorial] The truth is out there, somewhere

The Lancet - Sa, 01/08/2020 - 00:00
The tidal wave of information on the internet concerning the COVID-19 pandemic has resulted in difficulties in discerning truth from fiction. This so-called infodemic, defined by WHO as an “overabundance of information—some accurate and some not—that makes it harder for people to find trustworthy sources and reliable guidance when needed”, has become a major threat to public health. Infection rates will rise if people are confused about restrictions and patients may be harmed if they use unproven treatments or bogus remedies.

The Lancet - Sa, 01/08/2020 - 00:00
Screening for cancer is an important aspect of medical practice in this new millennium. It is well accepted that to decrease mortality due to oesophageal carcinoma, it is necessary to identify the malignancy at earlier, curable stages. In The Lancet, Rebecca Fitzgerald and colleagues1 report the results of a prospective, multicentre, pragmatic, randomised controlled trial, done at 109 sociodemographically diverse general practice clinics in England, which investigated whether offering the Cytosponge-trefoil factor 3 (TFF3) procedure to patients on medication for gastro-oesophageal reflux would increase the detection of Barrett's oesophagus compared with standard management.

[Perspectives] Why vaccine rumours stick—and getting them unstuck

The Lancet - Sa, 01/08/2020 - 00:00
Infectious diseases have long shaped human history, from the plague of Athens (430–427 BCE) that killed around a third of the Athenian population, the Black Death in the 14th century that killed about 30–60% of all Europeans, and the 1918–19 influenza pandemic that took the lives of at least 50 million people globally. In the 8 months since the emergence of SARS-CoV-2, more than 600 000 people worldwide have died from COVID-19 as of July 21, 2020.
