The most common symptoms of influenza (flu) include fever, a dry cough, headache, muscle and joint pain, a sore throat and a runny nose.

Each year, millions of people come down with flu. Most recover within a week, but for an unlucky few, flu can be deadly.

Seasonal flu epidemics typically occur in late autumn and winter, so we can anticipate them, and prepare accordingly.

In tropical regions, influenza can occur throughout the year, causing outbreaks more irregularly, but prevention is still important.

Here’s how you can protect yourself, and those around you.

Get vaccinated

Annual vaccination is the most effective way to protect yourself against flu, and serious complications.

Vaccination is especially important for pregnant women, at any stage of pregnancy.

It’s also crucial for children aged 6 months to 5 years, elderly people, those suffering with chronic medical conditions, and for health care workers.

Remember: a flu vaccine cannot give you flu. To feel achy or feverish after vaccination is a completely normal and natural reaction, and generally lasts only a day or two.

Wash your hands regularly

Clean hands protect against many infections, including flu. Keeping your hands clean is an easy way to keep yourself and your family healthy.

Wash your hands with soap and running water regularly and dry them thoroughly with a single-use towel. You can also use an alcohol-based handrub if you can’t get to soap and water.

Remember — washing your hands properly takes about as long as singing “Happy Birthday” twice.
