Many people originally called an epidemic "visitation, influence (of the stars)," from the Medieval Latin word influential. Italians also used the word influenza for diseases since at least 1504 because they, like those that used the Latin word influential , believed that the stars influenced health, according to the Douglas Harper Etymology Dictionary. Influenza in Italian literally means “influence.” The Italians would add the word influenza to the names of ailments. For example, influenza di febbre scarlattina was "scarlet fever."
Influenza type A viruses undergo two major kinds of changes. One is a series of mutations that occurs over time and causes a gradual evolution of the virus. This is called antigenic "drift." The other kind of change is an abrupt change in the hemagglutinin and/or the neuraminidase proteins. This is called antigenic "shift." In this case, a new subtype of the virus suddenly emerges. Type A viruses undergo both kinds of changes; influenza type B viruses change only by the more gradual process of antigenic drift and therefore do not cause pandemics.
This virus is awful! I got it a year ago around this time. Now I have it again. The first time I was sick for about a week
I couldn’t eat or drink anything. Eventually I was able to take small sips of Gatorade. This time around hasn’t been as bad as last time. It still sucks tho. At least I’m able to keep some pedialite down. Also, I’ve noticed the stomach cramps are worse this time, but I’m not violently throwing up like I was last time. It seems the best remedy for this is plenty or rest, pedialite (what you can handle), and let the god awful virus run its course. Hope everybody makes a swiftly recovery!!
