I. Introduction
Influenza, commonly known as the flu, is a viral infection that affects millions of people worldwide. According to the World Health Organization (WHO), seasonal flu epidemics cause up to 5 million cases of severe illness annually and 290,000 to 650,000 respiratory deaths. It is essential to understand the causes, susceptibility, symptoms, and prevention of flu to minimize its spread and severity.
II. Understanding the Transmission of Flu
Flu spreads mainly through respiratory droplets generated when infected people cough, sneeze, or talk. The virus can also survive on contaminated surfaces and be transmitted to healthy individuals who touch these surfaces. Flu is highly contagious, and people can spread the virus 1 day before symptoms develop and up to 7 days after becoming sick, making it tough to control its spread.
III. Factors that Increase the Risk of Contracting Flu
Several factors increase the risk of contracting flu, including:
- People with weakened immune system, such as children under 5 years, pregnant women, and elderly people
- Close proximity to sick people
- Lack of vaccination
- Healthcare workers and caregivers
IV. Symptoms and Progression of Flu
The symptoms of flu usually begin one to four days after exposure to the virus and can range from mild to severe. They include:
- Fever and chills
- General malaise and fatigue
- Muscle aches and joint pains
- Headache and sore throat
- Runny or stuffy nose
- Cough and chest discomfort
The symptoms of the flu can develop and change over time, with fever and body aches being the most prominent symptoms in the early stages. Coughing and nasal symptoms usually develop later. In severe cases, the flu can cause complications such as pneumonia, bronchitis, or sinus and ear infections.
V. Tips to Prevent the Spread of Flu
The following tips can help prevent the spread of flu:
- Frequent hand-washing with soap and water or alcohol-based hand sanitizer
- Covering mouth and nose when coughing or sneezing with a tissue or sleeve (not hands)

- Take prescription antiviral medication prescribed by a doctor within 48 hours of onset of symptoms to shorten duration and severity of flu
VII. Conclusion
Flu is a highly contagious viral infection that affects millions of people worldwide. Understanding the causes, susceptibility, symptoms, and prevention of flu is essential to minimize its spread and severity. Following good hygiene practices, getting vaccinated yearly, and staying home when ill can help prevent flu.
