Analysis of wastewater is used in many settings for surveillance of SARS-CoV-2, but it remains unclear how well wastewater testing results reflect incidence. Denmark has had an extensive wastewater analysis system that conducts 3 weekly tests in ≈200 sites and has 85% population coverage; the country also offers free SARS-CoV-2 PCR tests to all residents. Using time series analysis for modeling, we found that wastewater data, combined with information on circulating variants and the number of human tests performed, closely fitted the incidence curve of persons testing positive
The first genome-wide hunt to find genetic risk factors for long COVID has yielded a hit: a DNA sequence near a gene called FOXP4, which is active in the lungs and in some immune cells.
The phenomenon known as "Long Vax Syndrome" is gaining attention among researchers as they seek to better understand the potential side effects of the Covid-19 vaccine. Similar to the long-lasting symptoms experienced by some individuals with "Long Covid," Long Vax Syndrome is characterized by headaches, extreme fatigue, blood pressure issues, and abnormal heart rates that can persist for weeks or even longer. However, it is important to note that the number of reported cases of Long Vax Syndrome is significantly lower than the number of reported cases of Long Covid.
Moderna said the regulatory applications come after positive data from a study of approximately 37,000 adults 60 or older in 22 countries. Its vaccine to protect from respiratory syncytial virus was found in these trials to be 83.7% effective as defined by two or more symptoms.
WEDNESDAY, July 5, 2023 (HealthDay News) -- For much of the COVID-19 pandemic, doctors have told patients who get a negative result after taking a rapid antigen test at home to test again 48 hours later. ...
Whether you have symptoms or not, repeat testing after 48 hours may be required to rule out COVID infection, researchers from the University of Massachusetts Medical School found.
More kids were diagnosed as having type 1 diabetes after the COVID-19 pandemic began, and researchers have yet to determine the mechanism behind this increased incidence rate, the authors of a new meta-analysis said in JAMA Network Open...
...To harness this potentially transformative tool in future, policymakers and other stakeholders must heed the evidence — and the lessons — now emerging from its use during the COVID-19 pandemic.
