Today is World Mosquito Day, which honors the work of Dr. Ronald Ross-the man who discovered that malaria was carried by mosquitoes. But malaria is not the only disease you can get from these nasty bloodsuckers. How can you protect yourself from other diseases like chikungunya?

Finally posting this piece, which I finished a while ago. This was part of my semi-private lessons on topics in scientific illustration, and was the first time I’d made a descriptive illustration in watercolour (usually, it’s Adobe Illustrator). I’ve discovered that I’m not so skilled in painting backgrounds, but it was an interesting learning experience, and I think that it would be fun to try again some day. I’m not crazy about the illustration board I use, since it curved severely under heavy washes, so next time I’ll probably use stretched or heavy hotpress paper. On the plus side, it holds up remarkably well to multiple layers of liquid masking fluid.

You have to be well prepared, well trained, and you need emotional resilience. I think emotional strength is just as important as the experiences and the credentials—people have to be strong and not fall apart when things don’t go their way. It has to do with using your human abilities to the utmost.
