<s>[INST] How do you catch a cold or flu? [/INST] Either through the air – the viruses travel in droplets when an infected person coughs, sneezes or speaks – or from picking them up from a hard surface, such as a door handle, and transferring them to your nose, mouth or eyes. Cold symptoms develop 1-3 days after exposure; for flu symptoms, it’s 1-4 days. Source: Holland & Barrett.
