Global Rise in Influenza Cases
Flu season has arrived, and health experts are closely monitoring a global rise in influenza cases. In its latest update, the World Health Organization (WHO) reported that influenza A viruses remain the dominant strain worldwide, though transmission patterns vary across regions and hemispheres.
In the Southern Hemisphere, influenza activity has generally stayed low and stable. However, a few countries in Eastern Africa and Southeast Asia have reported higher positivity rates — exceeding 10% in some locations. Meanwhile, the Northern Hemisphere is experiencing a more noticeable increase, with positivity rates above 30% in several countries across Central America, the Caribbean, Western and Middle Africa, and parts of Asia.
Among the active virus types, influenza A(H1N1)pdm09, commonly known as swine flu, remains the most common subtype in Central America, the Caribbean, and parts of Africa. Meanwhile, Influenza A(H3N2) is currently the main circulating subtype across Asia. In Western Africa, both A(H1N1)pdm09 and A(H3N2) are spreading at similar levels. Although the current global trend does not yet indicate a severe outbreak, health authorities warn that influenza transmission remains active in multiple regions — a reminder that the flu continues to be a significant seasonal concern.
What Is Influenza (the Flu)?
Influenza, or simply the flu, is a contagious respiratory infection caused by the influenza virus. It primarily targets the nose, throat, and lungs, leading to symptoms that can range from mild to severe.
While most people recover within a week, the flu can become serious for young children, elderly adults, pregnant women, and people with chronic medical conditions. In more severe cases, it can lead to pneumonia, dehydration, or worsening of heart and lung diseases.
Many people confuse the flu with the common cold. However, flu symptoms typically appear suddenly and tend to be more intense, often accompanied by high fever and exhaustion that can last for several days.
Common flu A symptoms and a influenza symptoms include:
- Fever and chills
- Headache and body aches
- Sore throat
- Persistent cough
- Fatigue
- Nasal congestion or runny nose
When Is Flu Season?
In the Northern Hemisphere—which includes countries such as the United States, Japan, and much of Europe—flu season typically runs from October to May, with the peak period between December and February. During this time, colder weather keeps people indoors and closer together, allowing viruses to spread more easily.
In tropical and subtropical regions, such as Southeast Asia and parts of Africa, influenza transmission can occur year-round but often intensifies during the rainy season or periods of high humidity. Because of these different patterns, public health authorities encourage people to get vaccinated annually, as flu strains and intensity can change each year.
What Causes the Flu?
The influenza virus is the main cause of the flu. Among its types, Influenza A, B, and C are the most common strains that infect humans. Influenza A and B are typically seasonal viruses, with most cases appearing during the colder months, and they often cause more intense symptoms such as high fever, fatigue, and body aches. In contrast, Influenza C tends to cause milder infections and is not seasonal — meaning its occurrence remains relatively constant throughout the year.
Notably, H1N1 (commonly known as “swine flu”) and avian or “bird flu” are both subtypes of Influenza A, capable of spreading between animals and humans and sometimes triggering regional or global outbreaks.
Is the Flu Contagious?
Yes. The flu is highly contagious and spreads mainly through tiny droplets released when an infected person coughs, sneezes, or talks. These droplets can land in the mouths or noses of people nearby or linger on surfaces where the virus can survive for several hours.
Experts estimate that each person infected with the flu can transmit it to one or two others. A person is typically contagious one day before symptoms appear and up to a week after becoming sick. This means you can pass the virus to others even before realizing you have it.
Practicing good hygiene—such as washing your hands regularly, covering your mouth and nose when coughing, and staying home when sick—can significantly reduce the risk of spreading the infection.
How Can You Prevent the Flu?
The best way to protect yourself from the flu is by getting the influenza vaccine every year. Vaccination is available either as a flu shot or as a nasal spray, and it helps your immune system recognize and fight the latest circulating strains. Because the virus mutates frequently, annual vaccination is essential for maintaining effective immunity.
In addition to vaccination, several simple habits can help reduce your risk of catching or spreading the flu:
- Wash your hands frequently with soap and water for at least 20 seconds. If soap and water aren’t available, use an alcohol-based hand sanitizer.
- Cover your mouth and nose when you cough or sneeze — use a tissue or your elbow instead of your hands.
- Avoid close contact with people who are sick, and stay home if you’re not feeling well to prevent infecting others.
- Wear a mask if you’re ill and need to be around other people, especially in crowded or enclosed spaces.
- Avoid touching your face, particularly your eyes, nose, and mouth, as these are common entry points for viruses.
- Do not share eating utensils, cups, or food with others to reduce the risk of transmission.
Practicing these preventive measures — alongside regular vaccination — can significantly lower your chances of getting infected and help protect those around you during flu season.
