And here's some of their tentative plans, which are instructive:
Our campus community, a “city” of 50,000+ people, is highly unusual in its makeup. At least 80% of our population is made up of young people, say, 35 and under. All data to date tell us that the COVID-19 virus, while it transmits rapidly in this age group, poses close to zero lethal threat to them.
Meanwhile, the virus has proven to be a serious danger to other, older demographic groups, especially those with underlying health problems. The roughly 20% of our Purdue community who are over 35 years old contains a significant number of people with diabetes, asthma [sic], hypertension, and other ailments which together comprise a very high percentage of the fatal and most severe COVID-19 cases.
We will consider new policies and practices that keep these groups separate, or minimize contact between them. Literally, our students pose a far greater danger to others than the virus poses to them. We all have a role, and a responsibility, in ensuring the health of the Purdue community.
The approaches below are preliminary, meant to be illustrative of the objectives we will pursue. View them as examples, likely to be replaced by better ideas as we identify and validate them.
They could include spreading out classes across days and times to reduce their size, more use of online instruction for on-campus students, virtualizing laboratory work, and similar steps.
We will look to protect the more vulnerable members of our community by allowing (or requiring, if necessary) them to work remotely. Like the rest of society, we are learning a lot right now about which jobs are most amenable to remote work, and about new and better ways to do such work.
We intend to know as much as possible about the viral health status of our community. This could include pre-testing of students and staff before arrival in August, for both infection and post-infection immunity through antibodies. It will include a robust testing system during the school year, using Purdue’s own BSL-2 level laboratory for fast results. Anyone showing symptoms will be tested promptly, and quarantined if positive, in space we will set aside for that purpose.
We expect to be able to trace proximate and/or frequent contacts of those who test positive. Contacts in the vulnerable categories will be asked to self-quarantine for the recommended period, currently 14 days. Those in the young, least vulnerable group will be tested, quarantined if positive, or checked regularly for symptoms if negative for both antibodies and the virus.
Again, these concepts are preliminary, intended mainly to illustrate an overall, data-driven and research-based strategy, and to invite suggestions for their modification or exclusion in favor of better actions. They will be augmented by a host of other changes, such as an indefinite prohibition on gatherings above a specified size, continued limitations on visitors to and travel away from campus, required use of face coverings and other protective equipment, frequent if not daily deep cleaning of facilities, and so forth.
