According to Scientific American, the earth rotates at about 1,000 miles an hour. It orbits around that sun at about 67,000 miles per hour. It moves around the center of our galaxy at about 490,000 miles per hour. So, how come we do not feel this? Our immediate perceptions do not allow it because we, and everything on the earth, are moving at these same speeds. Not so long
Cross-protection from seasonal epidemics of human coronaviruses (HCoVs) has been hypothesized to contribute to the relative sparing of children during the early phase of the pandemic. Testing this relies on understanding the prepandemic age distribution of recent HCoV infections, but little is known about their dynamics. Using England and Wales as a case study, we use a transmission model to estimate the duration of immunity to seasonal coronaviruses, and show how cross-protection could have affected the age distribution of susceptibility during the first wave, and could alter SARS-CoV-2 transmission patterns over the coming decade.
