    • Sudden or excessive fatigue. Shorter days and reduced sunlight can make you feel tired. There’s a difference between being tired and experiencing extreme fatigue.

    • Cough. A persistent dry cough can indicate an early illness. It may be a warning sign of the flu. The flu virus can also cause a cough with wheezing and chest tightness.

Influenza is commonly called the flu, but it's not the same as stomach \\"flu\\" viruses that cause diarrhea and vomiting.For most people, influenza resolves on its own. But sometimes, influenza and its complications can be deadly. People at higher risk of developing flu complications include: 1. Young children under age 5, and especially those under 12 months 2. Adults older than age 65 3. Resident...

    Initially, the flu may seem like a common cold with a runny nose, sneezing and sore throat. But colds usually develop slowly, whereas the flu tends to come on suddenly.

Headache 5. Dry, persistent cough 6. Fatigue and weakness 7. Nasal congestion 8. Sore throat

    Flu viruses travel through the air in droplets when someone with the infection coughs, sneezes or talks. You can inhale the droplets directly, or you can pick up the germs from an object — such as a telephone or computer keyboard — and then transfer them to your eyes, nose or mouth.People with the virus are likely contagious from the day or so before symptoms first appear until about five days after symptoms begin. Children and people with weakened immune systems may be contagious for a sligh...

    Factors that may increase your risk of developing influenza or its complications include: 1. Age. Seasonal influenza tends to target children younger than 12 months of age and adults 65 years old or older. 2. Living or working conditions.

But children and adults at high risk may develop complications such as: 1. Pneumonia 2. Bronchitis 3. Asthma flare-ups 4. Heart problems 5. Ear infectionsPneumonia is the most serious complication. For older adults and people with a chronic illness, pneumonia can be deadly.

    The Centers for Disease Control and Prevention (CDC) recommends annual flu vaccination for everyone age 6 months or older.Each year's seasonal flu vaccine contains protection from the three or four influenza viruses that are expected to be the most common during that year's flu season. This year, the vaccine will be available as an injection and as a nasal spray.In recent years, there was concern that the nasal spray vaccine wasn't effective enough against certain types of flu. However, the n...

    Spotting the early signs and symptoms of flu can help you seek treatment that can shorten the course of an infection. The most common early symptoms are:1 1. Sudden high fever (over 100.4 degrees F) 2. Chills 3. Generalized muscle aches 4. Malaise (a general feeling of unwellness) 5. Tiredness 6. Headache (usually extending across the forehead and behind the eyes) Once full-fledged acute symptomsdevelop, there is really nothing you can do other than rest and let the disease run its course.

    The flu is caused by a family of viruses that affect the respiratory system. Unlike colds, which can be caused by any number of different viruses (including rhinoviruses, adenoviruses, and coronaviruses), flu is caused exclusively by influenza viruses (designated as influenza type A, B, C, or D). When flu symptoms first develop, it may be hard to differentiate them from the early signs of a cold. But, there are a few key ways to tell them apart. Flu viruses almost invariably have a shorter incubation period, meaning that symptoms tend to develop fast and furiously, usually within a day or so.2 Because of this, the immune systemwill respond more aggressively, flooding the body with inflammatory compounds to help neutralize the virus. This aggressive immune assault will manifest with symptoms that are usually more severe and/or less characteristic than the common cold.

    The flu can usually be diagnosed by symptoms alone, particularly during flu season. This is especially true with the prodromal flu symptoms, during which treatment will often be dispensed presumptively. Even if a rapid influenza diagnostic test (RIDT) is available, the test is not all that sensitive and can regularly return false-negative results.4 To prevent complications and the further spread of infection, certain prescription flu medications can be dispensed over the phone by a doctor or a telehealth physicianwithout a face-to-face meeting.

    Unlike the common cold, for which there are no drug treatments, the flu can be shortened by a day or two if certain antiviral drugs are taken within 24 to 48 hours of the first appearance of symptoms. The drugs work by slowing the replication of the virus and, by doing so, potentially reduce the length and severity of the illness.5 Even so, the drugs don't always work, often because people miss the early signs and get treated too late. If not taken within the first 24 to 48 hours, the drugs will likely be of any benefit. The four antiviral treatment options approved by the U.S. Food and Drug Administration (FDA) are: 1. Rapivab (peramivir), approved for adults and children 2 years and up 2. Relenza (zanamivir), approved for adults and children over 7 years6 3. Tamiflu (oseltamivir), approved for adults and children over 12 months7 4. Xofluza (baloxavir marboxil), approved for adults and children over 12 years8 For people that are at high risk of flu complications(including young...
