<s>[INST] How does the cold and flu spread? [/INST] The common cold and flu are mainly spread through coughs and sneezes, which propel droplets up to four feet in the air. These can then land in the mouth, nose or eyes of people nearby. Alternatively, viruses can spread when someone touches these droplets and then touches their mouth or nose. Most healthy adults may infect others beginning 1 day before symptoms develop, and up to 5 to 7 days after becoming sick. That means that you will be able to pass on the flu to someone else before you know you are sick, as well as while you are sick. Source: Theraflu. Link: https://www.theraflu.com/faqs/.
