H1N1 Surge: Infection Can Occur Without A Fever
H1N1 is a virus that can make people sick.
Many people with it develop a fever, but some do not.
The article says about one in seven patients may have H1N1 without a fever.
Other signs can include coughing, a sore throat, a blocked or runny nose, tiredness and body aches.
These signs can look like a common cold.
People who are older, pregnant, very young, immunocompromised or have certain health conditions may face greater risks.
Anyone with serious symptoms such as trouble breathing or chest pain should seek medical help.
Washing hands, avoiding sick people, staying home when ill and getting an annual flu vaccine can help reduce risk.
About one in seven H1N1 patients may not develop a fever, according to the article.
Possible symptoms include cough, sore throat, runny nose, fatigue, headache, body aches and shortness of breath.
Early signs can resemble a common cold and include a scratchy throat, dry cough, fatigue and nasal congestion.

Breathing difficulty, chest pain, bluish lips, confusion, dizziness and severe dehydration require medical attention.
