Cold and cough remedies are useful to manage colds, but do they suppress the body's defences against viral infections? If they do, they could increase the risks of Covid-19 infections and other similar infections (for instance H1N1). Because of the large number of people exposed to such infections, we need a quick and definitive answer to this question. Speculation may not suffice. Can we get some publishable research done soon?
