Flu

What is the flu?

The flu, also known as influenza, is a common illness caused by a virus. It spreads easily from person to person through the air when an infected person coughs or sneezes. Many people think the flu is just like a cold, but it is much more serious. In Africa, flu outbreaks can be deadly, especially among young children, pregnant women, and the elderly.

How common is the flu in Africa?

Many people in Africa get the flu each year, but because healthcare services are not always easily accessible, the exact number of cases is often unknown. According to the world health organization (WHO), influenza causes up to 650,000 deaths globally every year. In sub-Saharan Africa, flu-related complications are more severe because of factors like poor healthcare access and pre-existing conditions such as malaria, HIV, and malnutrition.

How is the flu different from a common cold?

The flu and the common cold have similar symptoms, but the flu is more severe and can lead to serious health problems. Here’s how to tell them apart:

Similar symptoms of cold and flu:

  • Runny or stuffy nose
  • Sneezing
  • Body aches
  • Fatigue (feeling weak or tired)

Symptoms that are more common with the flu:

  • High fever (above 38°C/100.4°F) – Colds rarely cause fever, but flu does.
  • Severe body aches – With flu, you may feel pain all over your body.
  • Dry cough and chest discomfort – Flu often causes a persistent dry cough that can last for weeks.
  • Extreme tiredness – Flu can leave you feeling completely drained of energy.
  • Headaches – Common with flu but rare with colds.

If you feel very sick or your symptoms last more than a week, seek medical attention immediately.

What are the dangers of the flu?

The flu can lead to serious complications, especially in children, pregnant women, the elderly, and people with chronic illnesses such as asthma or diabetes. Some flu-related complications include:

  • Pneumonia: A severe lung infection that can be fatal.
  • Sinus and ear infections: Can cause pain and further illness.
  • Sepsis: A life-threatening condition where the body attacks itself in response to an infection.

How to protect yourself from the flu?

Flu spreads quickly, but there are simple steps you can take to protect yourself and your family:

  • Get vaccinated: The flu vaccine helps your body fight the virus before you get sick.
  • Wash your hands often: Use soap and water to kill germs.
  • Avoid crowded places during flu season: The flu spreads easily in schools, churches, and markets.
  • Eat a healthy diet: A strong immune system helps fight infections.
  • Stay home if you are sick: This prevents spreading the flu to others.
  • Wear a mask in public if you have flu symptoms: Protect others from getting infected.

How does the flu vaccine work?

The flu vaccine is a small injection that teaches your body to recognize and fight the flu virus. Some people avoid the flu vaccine because they believe it will make them sick. However, the vaccine cannot give you the flu because it contains a weakened or dead version of the virus.

After getting the vaccine, you may feel mild symptoms like soreness at the injection site, mild fever, or fatigue for a day or two. This is normal and shows that your body is building protection against the flu.

How long does the flu last?

Most flu cases last about one week, but some symptoms, like fatigue and cough, can last for two or more weeks.

When should you see a doctor?

  • If your fever lasts more than three days
  • If you have difficulty breathing or chest pain
  • If you feel dizzy or confused
  • If a child has difficulty waking up or has a bluish skin color

What to do If you have the flu?

If you have flu symptoms, follow these steps:

  • Rest and stay hydrated: Drink plenty of water, soup, and natural fruit juices.
  • Take over-the-counter medication: Pain relievers like paracetamol can help reduce fever and aches.
  • Avoid alcohol and smoking: These weaken your immune system.
  • Use home remedies: Ginger, honey, and lemon tea can help relieve flu symptoms.
  • Stay away from others: Prevent the spread of flu by covering your mouth when coughing or sneezing.

If symptoms worsen, visit a hospital or clinic as soon as possible.

Conclusion?

The flu may seem like a minor illness, but it can be dangerous if not taken seriously. Every year, thousands of people in Africa die from flu-related complications. Protect yourself and your loved ones by getting vaccinated, maintaining good hygiene, and seeking medical help when needed.
