Homoeopathy can offer as preventive measures to many diseases because it's one of natural system of treatment, not claiming to be treatment of coronavirus.

In 6th edition of organon of medicine aph. 100, 101, 102 (footnote) and 241. Dr. Hahnemann itself never use this word, instead of it ‘homoeopathic (specific) remedy’ is used. Kent also says that in an epidemic, one may find half-a-dozen remedies that are daily indicated and one of these remedies seems to be the best suited for prophylaxis and this may differ from the curative one.
Genus epidemicus is an important part of Homoeopathic laws which means to find a probable remedy that can prevent from that particular epidemic.

So some Homoeopathic remedy is searched in case of outbreak of some epidemics and endemic diseases which matches the outbreak disease symptoms.

References from 6th edition of organon of medicines

§ 100: In investigating the totality of the symptoms of epidemic and sporadic diseases it is quite immaterial whether or not something similar has ever appeared in the world before under the same or any other name. The novelty or peculiarity of a disease of that kind makes no difference either in the mode of examining or of treating it, as the physician must any way regard to pure picture of every prevailing disease as if it were something new and unknown, and investigate it thoroughly for itself, if he desire to practice medicine in a real and radical manner, never substituting conjecture for actual observation, never taking for granted that the case of disease before him is already wholly or partially known, but always carefully examining it in all its phases; and this mode of procedure is all the more requisite in such cases, as a careful examination will show that every prevailing disease is in many respects a phenomenon of a unique character, differing vastly from all previous epidemics, to which certain names have been falsely applied – with the exception of those epidemics resulting from a contagious principle that always remains the same, such as smallpox, measles, etc.

§ 101 It may easily happen that in the first case of an epidemic disease that presents itself tothe physician's notice he does not at once obtain a knowledge of its complete picture, as itis only by a close observation of several cases of every such collective disease that he can become conversant with the totality of its signs and symptoms. The carefully observing physician can, however, from the examination of even the first and second patients, oftenarrive so nearly at a knowledge of the true state as to have in his mind a characteristic portrait of it, and even to succeed in finding a suitable, homoeopathically adapted remedyfor it.

§ 102 (Footnote): The physician who has already, in the first cases, been able to choose a remedyapproximating to the homoeopathic specific, will, from the subsequent cases, be enabledeither to verify the suitableness of the medicine chosen, or to discover a more appropriate, the most appropriate homoeopathic remedy.

§ 241: Epidemics of intermittent fever, in situations where none are endemic, are of the natureof chronic diseases, composed of single acute paroxysms; each single epidemic is of a peculiar, uniform character common to all the individuals attacked, and when thischaracter is found in the totality of the symptoms common to all, it guides us to thediscovery of the homoeopathic (specific) remedy suitable for all the cases, which isalmost universally serviceable in those patients who enjoyed tolerable health before theoccurrence of the epidemic, that is to say, who were not chronic sufferers from developed psora.
