Is the problem of protecting people from this coronavirus and curing them once infected, wholly one of the target individual’s personal beliefs?

It is a bit more complicated than that, but this is a big factor and the most important. Because of free will, people have become corrupted to feel vulnerable, to doubt their own strength, and in particular to doubt the power of the divine, or the motives of the divine, or the existence of the divine as a potential influence that is real and that they can summon as a source of help. When such individuals become ill, as with this virus, they have already put handcuffs on Creator through their non-belief, so it is much harder for us to bring healing, and therefore such individuals remain a tremendous risk to all the human beings around them because they will be on their own to sink or swim and will remain infectious until things work their way out. If they remain a carrier of the virus, it is worse then because they will continue to be a threat to be around. They may become reinfected and then repeat the situation where they are a biohazard for a period of time and help keep this drama going. That is a high price to pay for being out of divine alignment in neglecting the cultivation of their spiritual side and losing faith in God, and in the process becoming disconnected and vulnerable. We have the power to make any miracle happen, but if there is already a miracle underway in launching the divine human community to have the privileges and rewards both of free will and free agency, we cannot override the rules of engagement and undercut human free will by doing a last-minute save. That would be a violation of authority and would negate the whole meaning of the enterprise. It would not be your victory if we do this for you. It is not different than sending your child off to school but then at the eleventh hour when they are about to fail a final exam, you show up and give answers to them they have not learned so they can pass the test and graduate. But then what would that mean, if they have a distinction they truly failed to earn, but only did it through the help of a higher power? We want people to have the best of both, to not only survive and thrive unhindered and unencumbered, unafraid, and unhurt by the living things around them, we want them to be strong enough and to use every resource at their disposal, including reaching out to the divine to tackle the biggest problems they are unable to solve on their own. That is the true test of their authority and their intelligence and wisdom, to cultivate a higher awareness that the divine is real and accept and promote inner faith they have the standing to ask for divine assistance. That is not a weakness, but a strength and will bring many, many rewards.
