For those of you struggling in the US right now, please see the following website for financial assistance from the federal government as part of the CARES ACT. Note, I do not work for H&R Block, I just found this website very helpful after reading for hours on this.

Small businesses (including AirBnB hosts which are generally referred to as independent contractors by the IRS) have four options. These include EIDL (Economic Injury Disaster Loans from the Small Business Administration (SBA)), PPP (Paycheck Protection Program), Employee Retention Credit, and payroll tax postponement.
You are also generally eligible to file for unemployment at the State level. These vary from state to state. Loss of income, as long as it is about 50% or so, is generally a sufficient reason for most states.
Act quickly on these. Take charge of this situation. You are not alone. You can and will get through this and we will all go back to making money by hosting. Be resilient and fight for these. There are stories of people having success using the CARES ACT. I am trying several of these myself.
