"Doctors were at a loss as to what to recommend to their patients; many physicians urged people to avoid crowded places or simply other people. Others suggested remedies included eating cinnamon, drinking wine or even drinking Oxo's meat drink (beef broth). Doctors also told people to keep their mouths and noses covered in public. At one point, the use of aspirin was blamed for causing the pandemic, when it might actually have helped those infected. June 28, 1918, a public notice appeared in the British papers advising people of the symptoms of the flu; however, it turned out this was actually an advertisement for Formamints, a tablet made and sold by a vitamin company. Even as people were dying, there was money to be made by advertising fake "cures." The advert stated that the mints were the "best means of preventing the infective processes" and that everyone, including children, should suck four or five of these tablets a day until they felt better. Americans were offered similar advice about how to avoid getting infected. They were advised not to shake hands with others, to stay indoors, to avoid touching library books and to wear masks. Schools and theaters closed, and the New York City Department of Health strictly enforced a Sanitary Code amendment that made spitting in the streets illegal, according to a review published in the journal Public Health Reports."
