It's in the papers every day. Updates and instructions are being sent home from school. This will be a BAD flu season! During the week of September 13-19, indicators show that flu activity is increasing. Check out the CDC web site for detailed information: http://www.cdc.gov/h1n1flu/
Wash your hands frequently, cough and sneeze into your arm or a tissue (not your hand), and get prepared NOW to be able to work from home with remote network access in case you need to. The CDC is advising everyone who gets sick to STAY home. Maybe it won't be you, but your children may be sent home for a week.
There are MANY great options to work remotely, so just pick one and don't make it a last minute panic. LogMeIn, Remote Desktop, GoToMyPC, VPN (Virtual Private Network) -- all are great options that don't cost a lot. A small effort today to configure remote access will mean less down time when/if schools are closed or you get sick. Pick a solution, get it configured, and you will have one less thing to worry about.
