It explains how you get sicknesses that you already have when you already had it. Like One example is that a lot of the time with the flu it isn’t the same as the flu you got before. That it is slightly different even though it feels the same. Another is that the bacteria can mutate so that it is resilient against stuff that kills it.
The article I thought was really informative because it explains a lot of things that weren’t known to me. It did a lot of in depth speaking about the four different reasons why you would get sick again from the same illness when your body is suppose to have a immunity to things that you already had.

In Japan they give out a lot of drugs for virus and diseases but not everyone is using them responsively. So the virus are building up a immunity to the drugs they survived. They found that certain flu virus that are less common are showing up to be more resilient to the current vaccines. So they have to come out with new drugs to fight them more effectively.
I think that they shouldn’t be giving out the drugs so much because it is bad for people to be so dependent on the drugs that the effectiveness goes down. On top of this they aren’t taking all of them so that the virus isn’t be totally killed. So the viruses are getting harder to kill.


In Alaska there are a lot of wolves. On top of that a lot of the villages are isolated so it’s easy to be attacked and hard to get treatment. In Alaska rabies is very rare but when it does accrue it can be very problematic. Since rabies is a fatal virus and can’t be cured unless caught in the first stages. So what the people in Anchorage have to do is kill any dogs that are attacked by the wolves and kill any stray dogs.
It is a very serious treat to everyone around the wolves due to the fact that rabies is so dangerous because it takes so long to find out if an animal that attacked you had rabies if not caught. You also have to take multiple shots to prevent getting rabies, which takes up to a couple of months to finish. Which is why its such a big deal to the people in Anchorage.
