Binomial probability of a rare event is a key for successful prescription of genus epidemicus

Corona Virus Disease is an overwhelming global pandemic leaving all the world in an exceptional catastrophe. The impact of this crisis is proven encumbrance for public health arrangements across the world. Vaccine is a most sought-after alternative for overcoming this pandemic, but exceedingly time consuming, costly, and inclusive of many unwelcome health hazards. Homeopathy traditionally offers very costeffective, time saving, simple and speedy solution for overpowering the epidemic. Successful treatment of such epidemics is neither anunprecedented nor isolated event. It has cured many epidemics since the evolution of this therapeutic system for instance cholera, scarlet fever etc. Homoeopathic method of genus epidemicus lacks scientific explanation and reproducibility. The present study attempts to provide a scientific and methodological boost to derive single simple homeopathic remedy which can be prophylactic as well as curative. The current study applied the probability of rare event through binomial probability distribution equation; b(x; n, P) = nCx * P * (1 – P) – .Homoeopathic symptoms were taken from historical (literature reported) cohort. The remedy was analyzed through RADAR 10.0 software. Statistical analysis was carried through MS Excel 2013.After putting the values derived from occurrence of symptoms among patients with COVID, veratrum viridi was the suggestive remedy for given cluster. The remedy was derived from binomial probability of rare event. The cluster taken during this analysis reported vomiting and vomiting and abdominal pain were statistically rare events[Pr (A) <0.05]. Homoeopathic genus epidemic can offer cost effective therapeutic as well as prophylactic alternative among infectious disease epidemics such as COVID19, when scientifically based on certain statistical methods which in turns may bear precise and desired health outcomes.
