H1N1 Spikes: Fever Not Always a Symptom!

The Indian Council of Medical Research (ICMR) surveillance network has detected a significant rise in H1N1 cases, prompting increased public health awareness. It is crucial to note that H1N1 infection does not always manifest with a fever; approximately one in seven individuals may contract the virus without experiencing elevated body temperature.

Common symptoms that can indicate H1N1 infection include a persistent cough, sore throat, runny nose, fatigue, headache, and body aches. Early signs can be subtle, mimicking a common cold, with symptoms like a scratchy throat, dry cough, extreme fatigue, mild body pain, and nasal congestion.

Several factors can influence the absence of fever, such as an individual's immune response, age, the stage of infection, or the use of fever-reducing medication. Warning signs requiring immediate medical attention include difficulty breathing, chest pain, persistent high fever, bluish lips, dizziness, confusion, or severe dehydration.

High-risk groups for severe H1N1 include pregnant women, older adults, young children, individuals with diabetes, heart disease, lung disease, or compromised immune systems. Protective measures such as frequent handwashing, respiratory hygiene, avoiding close contact with sick individuals, staying home when symptomatic, and getting an annual influenza vaccination are essential.
