But there's a fast, cheap, effective way to deal with this, says the writer who lives on both sides of the high tech/low-tech divide. (No dishwasher, no smartphone, but computers and high-speed internet.)
Bright-colored (I suggest yellow, the color of the traditional plague flag--bright, easily noticed if it falls to the floor, etc.) 3x5 cards easily obtained in any office supply store, plus a stamp that says "Priority", an indelible marker (probably already at the ER intake desk) .
Step one: Hospital prints out a sheet to be taped to the staff side of the intake desk. It reminds staff to ask specifically about travel or residence in Guinea, Sierra Leone, or Liberia within the past 21 days. Staff doesn't have to remember which countries--it's right there in front of them. At the foot of the sheet is the in-hospital number they're to call if they "card" someone.
Step two: Upon getting a positive answer to the question, staff person writes patient's name on one card and hands it to the patient, asking the patient to wait right there. Staff person clips second card to clipboard; if patient used that clipboard to fill out information, use the same clipboard..
Step three: Staff person 1 calls the contact number that will immediately initiate response to possible Ebola patient. Upon arrival of team to ER waiting area, staff person 1 hands off clipboard to nurse or doctor, followed by immediate handwashing while another staff person, gloved, swabs down everything the patient touched.
Advantages, besides cheap, fast, and simple: no physical contact between patient and staff is required in the ER. Contact with other parts of the hospital is minimized--transport to an isolation area is controlled by a trained team, who will have with them, both protective garments and containment for any bodily fluids that emerge between the ER and isolation. ER staff beyond the admitting office are not contaminated and will not need even brief isolation (allowing the ER to continue to function) and anyone in the ER when the possible Ebola patient arrives can be identified immediately for follow-up.
