Colds and flu are the most common of all infections; on average every adult can expect to get two colds a year, and children can get up to 10 colds a year before they develop immunity. Flu is less common. Some people think they have flu when they just have a heavy cold – the symptoms are similar. Most colds and flu happen between September and March.
