Key Information About Flu
What Is Flu?
Also known as influenza, flu is a common viral infection of the lungs and airways. Even though it is similar to a bad cold, it can be more serious.
What Are the Symptoms of Flu?
Fever over 100.4 F, muscle pain, headache, sweats, dry cough, chills, persistent cough, tiredness, sore throat, weakness and nasal congestion are some common symptoms of flu.
What Are the Causes of Flu?
Flu is contagious. Viruses that cause this infection spread from person to person mainly by droplets of respiratory fluids sent through the air when someone infected with the virus coughs or sneezes.
These viruses can stay alive on inanimate objects for two to eight hours. If an infected person would have touched a surface, like a door knob or a cellphone, and you touch the same surface, you could get the virus. Once you have the virus on your hand, it can enter your body by touching your mouth, eyes, or nose.
Flu is caused by the influenza virus. There are three main types of this virus simply known as A, B and C:
Influenza virus type A – this is the most common type and causes annual outbreaks of flu.
Influenza virus type B – this is less common, causing outbreaks every three to five years.
Influenza virus type C – this type of virus presents the mildest symptoms, often similar to those of a cold.— Dr. Jen Tan, Immune System Expert
Bacterial pneumonia, ear infection, sinus infection, dehydration, bronchitis, and worsening of chronic conditions (like congestive heart failure, cancer asthma, diabetes, bronchitis, and kidney, liver or lung disease) are some known complications of flu.
People at High Risk for Complications From Flu
According to the CDC, individuals aged 65 and above are at a higher risk for serious complications from the flu. This is because the immune system weakens with age.
Treatment for Flu
Flu is primarily treated with rest and fluid intake to enable the body to fight the infection on its own. Doctors usually prescribe paracetamol, which is known to be effective against flu symptoms.
Decongestants are used in cases of nasal or sinus congestion. Use of antiviral drugs depends on the severity of symptoms. Patients with mild illness do not need antiviral drugs.
“Most people will recover in a couple of weeks, and if they have mild illness do not need to go to the emergency room,” said Mollie Vance, Lincoln County Health and Human Services Communicable Disease.
Nurse Mollis Vance said. “If the signs of flu are mild, the best thing to do is to stay home, rest and avoid others. If you are at high risk or concerned about your illness, call your healthcare provider.”
How to Prevent Flu?
One effective way to prevent flu is to get vaccinated. Stay away from people who are infected.
Keep your hands clean. Avoid touching your eyes, nose or mouth; preparing food; or eating with unwashed hands.
