Vox: Am I asymptomatic, or do I just really not want to have Covid-19? A guide.

Vox: Am I asymptomatic, or do I just really not want to have Covid-19? A guide.. “In December 2021, the Centers for Disease Control and Prevention changed its recommendations for isolation after a positive test, with the number of days someone must isolate being largely dependent on the presence of symptoms. Now, people who test positive but do not develop symptoms must isolate for just five days; if they remain asymptomatic, they can end isolation after five days (but continue to wear a mask around others at home and in public for another five days). To help you better understand what ‘counts’ as a symptom, Vox spoke to three experts.”

University of Georgia: Symptomatic COVID patients are more contagious

University of Georgia: Symptomatic COVID patients are more contagious. “Individuals with COVID-19 are most likely to spread the virus to close contacts two days before the onset of symptoms to three days after symptoms appear, and the risk of transmission is highest when patients had mild or moderate disease severity, according to a new study by researchers at the University of Georgia. The study, which was published this week in JAMA Internal Medicine, supports the idea that if a person with COVID-19 is sicker, they are more contagious compared to asymptomatic cases.”

Brief19: Coronavirus MRNA Vaccines Reduce The Risk Of Asymptomatic Infection

Brief19: Coronavirus MRNA Vaccines Reduce The Risk Of Asymptomatic Infection. “This research, conducted by the Mayo Clinic health system across its hospitals in Minnesota, Arizona, and Wisconsin, recruited patients requiring covid-19 testing 48 to 72 hours ahead of planned procedures and surgeries. The patients were divided into two cohorts: those who had received at least one dose of either vaccine and those who hadn’t had a shot yet at the time of the testing. Of the nearly 40,000 patients who were tested, 3.2 percent of the unvaccinated group tested positive, while only 1.4 percent of the protected group was found to have contracted SARS-CoV-2. This was a statistically notable difference and suggests a relative risk reduction of 44 percent after getting vaccinated for asymptomatic disease.”

USA Today: New Zealand study details COVID-19 spread on long-haul flight despite tests

USA Today: New Zealand study details COVID-19 spread on long-haul flight despite tests. “The 12-page report…follows a cluster of coronavirus cases linked to one passenger traveling on an 18-hour flight from Dubai to New Zealand in September. Though the traveler tested negative with a PCR test before the flight, researchers concluded that ‘at least four in-flight transmission events of SARS-CoV-2 likely took place’ as the pre-symptomatic yet contagious person infected at least four others. SARS-CoV-2 is the virus that causes COVID-19.”

New York Times: Even Asymptomatic People Carry the Coronavirus in High Amounts

New York Times: Even Asymptomatic People Carry the Coronavirus in High Amounts. “Most of the evidence for asymptomatic spread has been based on observation (a person without symptoms nevertheless sickened others) or elimination (people became ill but could not be connected to anyone with symptoms). A new study in South Korea, published…in JAMA Internal Medicine, offers more definitive proof that people without symptoms carry just as much virus in their nose, throat and lungs as those with symptoms, and for almost as long.”
