The forms result from the statistical surveys, which show the number of infections registered over a period of time—it is frequency distributions that assume waveforms. It should be noted that there are fundamental differences between an influenza wave and a COVID wave....
Many of these same characteristics have previously been demonstrated for influenza and other common respiratory viruses. These data provide a useful theoretical framework for possible aerosol-based transmission for SARS-CoV-2, but what is less clear is the extent to which these characteristics lead to...
Influenza (Flu) and COVID-19 are both contagious respiratory illnesses, but they are caused by different viruses. COVID-19 is caused by infection with a new coronavirus (called SARS-CoV-2) and flu is caused by infection with influenza viruses. There are some key differences between flu and...
with good intention, kept promising influenza vaccine to the public. And when it didn't arrive on time because of challenges growing the virus, when people got very upset and concerned, literally it threatened the credibility of HHS. I worry here that we don't over promise ...
Fig. 1. Some examples of (a) COVID-19, (b) influenza-A (H1N1), and (c) CAP cases in chest CT images. The red arrows indicate the locations of the main lesion regions. It can be seen that there are similar lesions among different types of pneumonia, which increases the challenge fo...
What's the difference between infectivity? Common Cold: It is not infectious. When the resistance decreases, some viruses colonized in the upper respiratory tract replicate, causing symptoms; Influenza: infectious; COVID-19: It i...
National Institutes of Health who wrote a book on influenza, told the AP. Still, "they can do terrible things while they're raging." There was one important caveat to the latest milestone: The U.S. population was one-third of the size it is today, so the 675,000 ...
Children infected with SARS-CoV-2 may be asymptomatic or have mild symptoms indistinguishable from other common upper respiratory tract infections,2,3allowing them to spread the virus when they feel well. Children are often key transmi...
Long COVID has been associated with a broad range of symptoms and health impacts5,7,8,9. A previous study showed that symptoms of long COVID, although commonly observed among patients with other viral infections such as influenza, occur more frequently following infection with SARS-CoV-210. Se...
Influenza (Flu Virus Type A and B) According to theCDC, the onset of flu symptoms is usually much faster and more intense than cold symptoms, and they are often accompanied by a fever. The flu can also have very seriousassociated complications. ...
