No publisher should feel obligated to attend congregation meetings at this time if they feel concerned or anxious about doing so.
This implies that JW should (are made to) feel obligated to visit meetings during normal times...
Please be assured, you are not being unfaithful for taking such precautions.
What about the JW in Russia and other areas where JW are banned or bullied? Will JW who take sensible precautions and worship Jehovah from home, without going to illegal meetings or joining in illegal preaching activities, be seen as unfaithful?
