What are the symptoms of flu?

The flu, or influenza, is a contagious respiratory illness caused by influenza viruses. Recognizing flu symptoms early can help you seek appropriate care and reduce the risk of spreading the virus to others. Common symptoms of the flu typically come on suddenly and may include: - **Fever or feeling feverish/chills:** Not everyone with the flu will have a fever, but it is a common symptom. - **Cough:** Usually dry and persistent. - **Sore throat** - **Runny or stuffy nose** - **Muscle or body aches** - **Headaches** - **Fatigue (tiredness)** - **Some people, especially children, may also experience vomiting and diarrhea**, though this is less common in adults. It’s important to note that flu symptoms can vary in severity and not everyone will experience all of these symptoms. If you or someone you care for has difficulty breathing, chest pain, persistent high fever, or severe weakness, seek medical attention promptly, as these can be signs of complications. If you suspect you have the flu, rest, stay hydrated, and consider contacting your healthcare provider, especially if you are in a high-risk group such as young children, elderly adults, pregnant women, or individuals with chronic health conditions.

The flu, or influenza, is a contagious respiratory illness caused by influenza viruses. Recognizing flu symptoms early can help you manage the illness and prevent spreading it to others. Common symptoms of the flu typically come on suddenly and can include: - **Fever** (often high, but not always present) - **Chills and sweats** - **Cough** (usually dry and persistent) - **Sore throat** - **Runny or stuffy nose** - **Muscle or body aches** - **Headaches** - **Fatigue and weakness** (can be severe) - **Some people may also experience nausea, vomiting, and diarrhea**, though these are more common in children than adults. If you or someone you care for experiences these symptoms, it’s important to rest, stay hydrated, and consider consulting a healthcare provider, especially if symptoms worsen or if the person is at high risk for complications (such as young children, elderly adults, pregnant women, or those with chronic health conditions). Early antiviral treatment can sometimes reduce the severity and duration of flu symptoms if started promptly.

The symptoms of the flu (influenza) typically come on suddenly and can range from mild to severe. Common signs to look out for include: - **Fever**: A high temperature, often above 100.4°F (38°C), though not everyone with the flu will have a fever. - **Chills and Sweats**: Feeling very cold and then sweating as the fever fluctuates. - **Body Aches and Muscle Pain**: Generalized muscle soreness and fatigue, often quite intense. - **Headache**: A persistent and sometimes severe headache. - **Fatigue and Weakness**: Feeling unusually tired and weak, sometimes lasting for weeks. - **Cough**: Usually dry and persistent, sometimes worsening over time. - **Sore Throat**: A scratchy or painful throat. - **Nasal Congestion or Runny Nose**: Stuffy or runny nose is common. - **Chest Discomfort**: Mild to moderate chest discomfort or tightness. In some cases, especially in children, nausea, vomiting, and diarrhea can also occur, although these are less common in adults. Because flu symptoms overlap with those of other respiratory infections, if you experience a sudden onset of fever with cough and body aches during flu season, it’s a good indication of the flu. If symptoms worsen or if you are in a high-risk group (such as young children, elderly adults, pregnant women, or people with chronic health conditions), it’s important to seek medical advice promptly.
