From Redemptionis Sacramentum. This 2004 Instruction of the Congregation for Divine Worship and Discipline of the Sacraments is in force now.
[91.] In distributing Holy Communion it is to be remembered that “sacred ministers may not deny the sacraments to those who seek them in a reasonable manner, are rightly disposed, and are not prohibited by law from receiving them”. Hence any baptized Catholic who is not prevented by law must be admitted to Holy Communion. Therefore, it is not licit to deny Holy Communion to any of Christ’s faithful solely on the grounds, for example, that the person wishes to receive the Eucharist kneeling or standing.
[92.] Although each of the faithful always has the right to receive Holy Communion on the tongue, at his choice, if any communicant should wish to receive the Sacrament in the hand, in areas where the Bishops’ Conference with the recognitio of the Apostolic See has given permission, the sacred host is to be administered to him or her. However, special care should be taken to ensure that the host is consumed by the communicant in the presence of the minister, so that no one goes away carrying the Eucharistic species in his hand. If there is a risk of profanation, then Holy Communion should not be given in the hand to the faithful.
This document does NOT say, “the faithful always has the right to receive Holy Communion on the tongue, at his choice except in time of viruses“. Bishops do not have, on their own authority, the ability to ignore RS, which established binding norms for the whole Latin Church.
There is greater risk of both profanation of the Eucharist and contagion via Communion on the hand, than there is through Communion on the tongue properly done.
Regarding Communion on the hand, the risk of contagion will be greatly reduced of the faithful are taught properly to hold their hands. However, the risk of contact remains greater via Communion on the hand, because the possibility of hand to hand contact is greater. It would be highly irreverent simply to drop the Sacred Host on someone’s palm.
