We covered this many years ago in high school. The consensus even then, in the 60s~70s was ... I dunno, but they sure are weird...

Chemical bonding.
Reproductive.
Seeking habitat.
Constantly evolving.
Recombining DNA/RNA structure sequencing.
Becomes larger/smaller with each generation.
Keeps to the same basic structure.
Can easily become devastating to host and body.

Overall -- weird stuff.

What's needed for the future for biotechnology in disease control is that sci-fi thing MIT now gives degrees for -- and now others such as Arizona State University, Drexel University, Johns Hopkins University, Joint School of Nanoscience and Nanoengineering, Louisiana Tech University, North Carolina State University, North Dakota State University, Radiological Technologies University Vermont -- nanotechnology. The virus needs to be met and fought on its own turf, possibly with the development of counter-viruses that dismantles or expands the bad virus outer coating of protein to make them easier for the human immune system to locate and destroy on its own.

Time, time, time... It just keeps running out...
