Flu

The flu typically progresses through three stages:

• Onset (1-3 days): Symptoms appear suddenly, including fever, chills, body aches, fatigue, and sore throat.
• Peak (3-5 days): Symptoms intensify, with a high fever, severe fatigue, headache, muscle aches, and cough.
• Recovery (1-2 weeks): Symptoms begin to subside, but fatigue and a lingering cough may persist.

Some people may experience complications, prolonging the recovery time.

Yes, the flu can lead to serious complications that require hospitalization, especially in high-risk groups such as young children, the elderly, pregnant women, and individuals with weakened immune systems or chronic health conditions. Complications include pneumonia, worsening of chronic respiratory diseases, dehydration, and secondary bacterial infections. When these complications occur, emergency medical care and hospitalization may be necessary to provide treatments like intravenous fluids, oxygen therapy, or antibiotics.

While adults and children can experience similar flu symptoms such as fever, cough, body aches, and fatigue, children—especially younger ones—may show additional signs like irritability, persistent crying, difficulty breathing, or refusal to eat or drink. Infants and toddlers are also at higher risk for severe symptoms and complications. Because children may not be able to communicate their symptoms clearly, caregivers should watch for warning signs such as rapid breathing, dehydration, bluish lips, or extreme lethargy, which require immediate medical attention.

Yes, the flu can exacerbate asthma and other chronic respiratory conditions like chronic obstructive pulmonary disease (COPD). The infection causes inflammation in the airways, leading to increased wheezing, coughing, shortness of breath, and asthma attacks. People with pre-existing respiratory conditions should monitor their symptoms closely during flu season and seek prompt medical care if symptoms worsen.

To prepare for a flu-related ER visit, gather important information such as your vaccination history, a list of current medications, and any known allergies. Note the onset and progression of symptoms, and be ready to describe any complications like difficulty breathing or dehydration. Bring identification and insurance information, as well as a mask to help prevent the spread of infection while at the facility. It’s also helpful to arrange transportation, as severe flu symptoms may make driving unsafe.
