The Flu: What It Is and How to Protect Yourself
Influenza, known as the flu, is a highly contagious respiratory illness caused by influenza viruses. This disease is a major public health concern, with the potential to cause severe illness, hospitalization, and even death. In this article, we’ll explore the symptoms, causes, and risk factors associated with the flu, as well as effective prevention and treatment strategies.
What is the Flu?
It is a contagious respiratory illness caused by influenza viruses that infect the nose, throat, and sometimes the lungs. Influenza viruses are highly contagious and can spread from person to person through droplets released when an infected person talks, coughs, or sneezes. This disease can also be contracted by touching a surface contaminated with the influenza virus and then touching one’s nose, mouth, or eyes.
Symptoms of the Flu
The symptoms typically appear one to four days after exposure to the virus and can last for several days to two weeks. Symptoms include:
- Fever
- Cough
- Sore throat
- Runny or stuffy nose
- Body aches
- Headache
- Chills
- Fatigue
In some cases, the flu can lead to severe illness, including pneumonia, and can be life-threatening, especially in young children, older adults, and people with certain medical conditions.
Causes and Risk Factors
It is caused by influenza viruses, which are constantly evolving and changing. There are several strains of influenza virus, and each year a new vaccine is developed to protect against the strains predicted to be most prevalent that season. It is most common during the fall and winter months, and people at higher risk of complications include:
- Young children
- Adults 65 years and older
- Pregnant women
- People with chronic medical conditions such as asthma, diabetes, or heart disease
- People with weakened immune systems
Prevention
Vaccination is the best way to prevent its spread. The vaccine is safe and effective, and can significantly reduce the risk of contracting the virus. The Centers for Disease Control and Prevention (CDC) recommends that everyone six months of age and older receive the vaccine every year. Other effective prevention strategies include:
- Washing hands frequently with soap and water or using an alcohol-based hand sanitizer
- Avoiding close contact with sick people
- Covering mouth and nose with a tissue or elbow when coughing or sneezing
- Avoiding touching eyes, nose, or mouth
- Staying home from work or school when sick
Treatment
There are several strategies that can help alleviate symptoms and prevent complications. These include:
- Getting plenty of rest
- Drinking fluids to stay hydrated
- Taking over-the-counter pain relievers such as acetaminophen or ibuprofen to reduce fever and relieve aches and pains
- Taking antiviral medications as prescribed by a healthcare provider
