I am an LCMS Lutheran physician, board certified in infectious diseases and trained in hospital epidemiology and public health. I work as an internal medicine hospitalist in Michigan. I have worked overseas in Haiti and India and am at the end of a 35 year career in infectious diseases care and training.
People like me have trained our entire careers for this epidemic. We have studied these epidemics with concern since the 1918 great influenza epidemic. This one is real and portends to be similar to the 1918 pandemic, but thankfully, is not killing children and young adults as the Spanish flu did.
My community has identified its first "index" cases of coronavirus just this week.
I very much appreciate pastor Matthew Harrison's communication and message. It is to be heeded. There is no reasonable reason to believe that the epidemic in the USA and Canada will behave any differently than in Italy.
We are on the precipice of a full blown epidemic which will threaten to kill some of our elder citizens. We must act purposefully, deliberately and peacefully within our vocations to respond to the advice of our God given leadership. Preparation as directed by CDC is not panic. It is to follow calmly the preparation necessary to love our neighbors.

I would recommend to following:

1. As it is Lent currently, sobriety and self denial to control this epidemic is in keeping with our Lutheran piety and love toward our neighbor.
2. I have recommended to my parish pastor that all meetings and events be cancelled or postponed except Divine Liturgy. Other parish activities could be transitioned to virtual platforms such as web-based meetings. With the blessings of modern technology we should be able to continue our ministries and outreach to those in need and keep our church life vibrant and active. I would recommend transitioning to this level of restriction if there are confirmed case(s) in your immediate county or the any adjacent county or if directed to so by any authority in your jurisdiction.
3. Social distancing short of quarantine is appropriate in all settings and locales currently. Handshakes and other forms of touching for communication should be stopped. Frequent handwashing and disinfection of commonly touched surfaces should be the norm.
4. Individuals with symptoms of coronavirus should not attend any public gatherings including church. Other means of providing sacramental care to the ill will need to be worked out.
5. We should be aware of fomites and alter our practices to control contagion through these means. Fomites are inanimate objects that can transmit infection once contaminated. In the use of our churches for Divine Liturgy articles that are vulnerable to being fomites are door knobs and openers, handrails and stairrails, bathroom faucet handles and toilet flushers, offering plates, church bulletins and hymnals that are hand distributed, communion rails, the chalice and articles for distribution of Holy Communion. As best as can be accomplished these should be touched as by few people as possible and those touching these articles should wash or sanitize their hands before and after use.
6. With regards to the distribution of Holy Communion I would suggest the following given my professional insights. I realize there are vital sacramental matters to the stewardship of this Gift that will require guidance from our pastors.
A. Distribute communion with the recipients standing rather than kneeling at the rail and touching the rail to receive. Reverence for Christ's body and blood can be given by bowing or other manners.
B. Wipe the chalice with something with greater than 70% alcohol content. One suggestion I have seen is Everclear which is 95%. However, any liquor greater than 140 proof should be effective.
C. For parishes that practice common cup, provide a way at the alter for the recipient to guide the chalice to their mouth without touching the chalice base with their hands and/or contaminating it with their hands.
D. For those handling all of these items, hand washing and hand sanitation practices are a must.

7. Anticipate that those whose vocations put them in the front lines of this epidemic will be taxed and challenged, and some will be endangered. These include clergy of all kinds, health care workers of all kinds, first responders of all kinds, and nursing home staff and managers. Support them with your prayers, kind words through media, loving support. For those who are able, strongly consider contributing your tithe and offerings a month in advance.

8. Realize that this stress will try to break even the most resilient members of our communities and churches. Love them, pray for them, talk them through this. Be self aware in advance and identify within your vocational responsibilities which of your neighbors will need extra support to navigate the threatening nature of this trouble. There is excellent guidance on remediating the psychosocial impacts of epidemics and quarantine on the internet.

9. Pastors and elders would do well in advance to think through the practical aspects of hospital visitation during this epidemic. Hospital and nursing home visitation will be restricted by infection control and public health officials.

10. Pastors and elders are advised to think though the practical aspects of funeral practice and bereavement care in the midst of an epidemic of this character.

Finally, as layperson acting out my vocation and vulnerable to danger, I would encourage creating a webbased modality for community wide prayer for those affected by this epidemic, again appropriate to our Lutheran piety and practice.
