Therefore, one who is in quarantine because of the Coronavirus and cannot go to the synagogue to hear the Megillah, should act in accordance with the following options listed in order of priority:
1. One should arrange for someone to read the Megillah close to one's home such that one will hear the reading directly, while maintaining the separation required for quarantine per the instructions of the local medical authorities.
2. One should read the Megillah himself out of a kosher scroll. One may use a recording of the reading for assistance and read along with the recording using the scroll. We can provide a link to a recording of the reading specifically designed for easy use in this scenario (contact: firstname.lastname@example.org).
3. One should hear the reading of the Megillah via a live broadcast, such as over the telephone or computer. One may answer "amen" to the blessings of the reader,5 but should not recite them oneself.
The custom is that one who reads the Megillah privately does not recite the blessing of "harav et rivenu" following the reading.6
