Asymptomatic COVID-19 Infections And ‘Disease Tolerance’ : Shots – Health News : NPR

The prevailing theory is that their immune systems fight off the virus so efficiently that they never get sick. But some scientists are confident that the immune system's aggressive response, the churning out of antibodies and other molecules to eliminate an infection, is only part of the story.

These experts are learning that the human body may not always wage an all-out war on viruses and other pathogens. It may also be capable of accommodating an infection, sometimes so seamlessly that no symptoms emerge. This phenomenon, known as disease tolerance, is well-known in plants but has only been documented in animals within the last 15 years.

Cloverleafs have fallen out of popularity due to the dangerous weaving conditions they create.

The Rochester Arterials were in many cases built early on in the Interstate era and have a lot of problems with weaving conditions and left handed exits and merges. Newer designs are better and they’ve been fixing them in recent decades.

Another interesting thing is the sharp curve at South Goodman Street on Interstate 490 – this is due to a sharp bend in the original Erie Canal which 490 follow, although they round a bit of the curve when they built the Interstate.

At the Can of Worms, the route of I 590 follows the original Erie Canal south bend – the sharp bend to the south from I 490 to I 590 was a feature of the Canal.
