The Giggles.

It was supposed to be a cure, you know? God I don't know what I'm doing here. I think I'm trying to apologize before it hits, I just want say that I'm sorry. It wasn't supposed to happen like this. If you're going to die from it, then you might as well know what it was...

Shit, I can hear laughter. It's distant though so I have some time.

Like I said, it was supposed to be a cure, something to help everyone. I was one of the chemist working on the project at the time, and I saw great potential in it. I could go into every detail of the chemicals molecular composition, but I don't have the time, and I don't think you would care. Either way, I started working on the project with a few of my co-workers.

The premise was, laughter is the best medicine, and whoever thought of this took it seriously. It was supposed to cure cancer by changing cells on a molecular level, and prevent them from turning cancerous. The only side effect to this new medicine was that it would cause the subject to laugh for a few hours. The first few test subjects we tired this on had highly successful results. It even removed tumors! It was surpassing our suspicions, and exceeding our expectations! However those first few subjects were mice.

We eventually worked our way up to cats and dogs. The cure seemed to work for every species! However I had been working on the project for over a year, and had decided to take a vacation to Europe. Of course that was when they decided to try human testing.

I read up on the reports just to keep in the know, but... That meant I was following as the realizations kicked in.

Crap! The laughter is getting closer! I have to close my windows, buy me some more time.

Needless to say, I knew something had gone wrong. They had stupidly tried this medicine on about twenty people at the same time... The chemical did something none of us expected. The human subjects... Kept laughing. They didn't stop. It got to the point where they couldn't breath, and my co-workers had to force oxygen into them just to keep them alive for a bit longer. They died soon after.

After that, the scientists started laughing as well, and then a whole town started laughing, and then a city. The medicine had turned into a toxin. It gathered in the subject's lungs and was forced out with each bit of laughter. That was when it became airborne, and highly contagious.

Contagious laughter. Isn't that ironic? I would laugh at that but... I'm already feeling kind of giggly.

Most of Europe is already dead, and the rest are on their way. The research facility was based in Australia so it took a while for it to finally get here, but-

The laughter is right outside my door... If you live in Canada you might have a chance still! Get out into the water! Get away from civilization! It's spreads through breath and it doesn't have a long life span outside of a body! Go! Ru...
