People who experience "brain fog" and other neurological problems following COVID-19 infection may be suffering from PTSD, researchers report.
Many of us feel obligated to perform acts for loved ones, such as calling more frequently or running an errand for an elderly friend, during this time of social distancing. Researchers report low-level obligations and acts of kindness can help strengthen relationships, while more substantive obligations can put a strain on relationships.
Undetected and undocumented cases of COVID-19 were largely responsible for the rapid spread of the virus in China. 86% of all infections were undocumented before the January 23 Wuhan travel shutdown. Per person, the undocumented infections were half as contagious as documented infections but were the source of two-thirds of documented infections.
Researchers report the median time from exposure to symptoms for the COVID-19 virus is 5.1 days. 97.5% of people who develop symptoms of coronavirus will do so within 11.5 days of exposure. For every 10,000 people quarantined for 14 days, an estimated 101 would develop symptoms after release.
Neurological symptoms associated with COVID-19, from losing the sense of smell to stroke, are linked to a six-fold higher risk of dying as a result of coronavirus.
Infectious disease experts report between 40% and 70% of adults could become infected with coronavirus during the outbreak. In a new interview, Dr. Lipsitch, head of Harvard's T.H. Chan School of Public Health's Center for Communicable Disease Dynamics, discusses the risks and spread potential of COVID-19, and addresses how the infection could impact children's' health.
A new genetic sequencing study reveals SARS-CoV-2, the virus responsible for coronavirus, originated from a single source in Wuhan, China. However, many of the localized cases in the US show Europe as the most likely source of infection. The study also identified a SARS-CoV-2 mutation that has never been seen before, where 81 of the letters have been permanently deleted from the genome. The mutation mirrors a large deletion that occurred during the 2003 SARS outbreak. During the mid-to-late phases of the 2003 SARS infection, the accumulated mutations attenuated the virus, leaving a weakened form of infection that resulted in less severe symptoms.
EIDD-2801, a new antiviral drug, has the potential to treat coronavirus. A new study reveals the drug can prevent severe lung injury in mouse models and cultured human lung cells infected with COVID-19. The drug will soon be ready for human testing.
Many people reported they felt like time was passing differently during the initial COVID-19 lockdowns. Researchers explore how the pandemic has contributed to the feeling of time distortion.
Researchers confirm ACE inhibitors and ARBS medications may increase the risk of patients with COVID-19 developing more severe symptoms.
Preliminary results from a new model suggest the COVID-19 lockdown should last for more than six weeks. The advice is based on data which shows it takes countries almost three weeks to see a growth rate staying below 10% and doubling time over seven days. It takes a month to keep the growth rate under control and at 1%, and 45 days to achieve containment.
Researchers have developed a new app that uses artificial intelligence technology to determine whether a person has COVID-19 based on the sound of their cough. The app has a 70% accuracy rate.
