Among patients experiencing the most trouble are people who had pre-existing pulmonary issues, heart problems, asthma and the elderly, said Thomas Ingmire, an emergency room doctor at Presbyterian Hospital.
Young people who are healthy before they catch the flu can often weather the illness without medical assistance as long as they make sure they stay hydrated and keep there temperatures under control, Ingmire said.
However, health officials say people who feel extremely sick and people at high risk of complications, including young children, elderly persons, pregnant women and people with certain pre-existing medical conditions, should seek advice from their health providers.

Typical flu symptoms include a fever, cough, sore throat, runny or stuffy nose, body aches, headaches, chills and fatigue.
