Brokaw has been the sole anchor of weekday ``NBC Nightly News'' since 1983, and has an impressive history of ``firsts,'' including: the first exclusive United States one-on-one interview with Mikhail Gorbachev, which earned him an Alfred I.
If you think it's the flu, avoid contact with others. Don't try to power through your day at work, you'll only risk exposing your coworkers and others you come in contact with. If you must go out, for instance to see a doctor, wear a face mask. Influenza is highly contagious, and often debilitating and even deadly.
If you have flu, you generally start to feel ill within a few days of being infected. You should begin to feel much better within a week or so, although you may feel tired for much longer. You will usually be most infectious from the day your symptoms start and for a further three to seven days. Children and people with weaker immune systems may remain infectious for longer.
