Actually, it sounds like you got a double infection with pinkeye to boot. It's too early in the year to be influenza, plus influenza usually doesn't cause vomiting--just incredble body aches and a high fever. I'd say you probably had a bacterial infection in your upper respiratory tract plus gastroenteritis caused by something you ingested or otherwise had contact with. Like mfh suggested, your body is probably unused to the germs in your new environment.
But mfh, one thing you should note--Lysol does kill viruses, including influenza and rhinovirus. Here is the complete list:
Viruses
- Influenza
- Rhinovirus -The leading cause of the common cold
- Rotavirus - The leading cause of infectious diarrhea in children
- Respiratory Syncytial Virus (RSV) – The leading cause of lower respiratory infection in children
- Poliovirus Type 1
- Adenovirus Type 2
- Herpes Simplex Virus Types 1 and 2
- Hepatitis A
Bacteria
- Escherichia coli (E-Coli)
- Salmonella
- Staph and Strep
- Campylobacter
Fungi
- Athlete’s Foot Fungus
- Mold and Mildew
The CDC has done a ton of research on the best ways to combat getting sick, and regular soap works just as well as antibacterial soap for washing with. However, they do recommend using hand sanitizer on a frequent basis, because it's often easier to use hand sanitizer than to wash one's hands frequently. Disinfecting surfaces where ickies like influenza or viruses that cause diarrhea to be shed in between deeper cleanings is actually a pretty smart idea. You may not totally prevent yourself from getting sick, but you certainly lessen the chances of illness.
Here is a neat poster from the CDC on keeping germs away:
