Influenza
What is Influenza (flu)?
Influenza (flu) is a common contagious respiratory illness that affects hundreds of thousands of Canadians each year. Influenza A and B viruses are the two main types that cause infection. The flu vaccine (flu shot)is the best way to protect against infection. 
What is my risk?
    Travellers are at risk in any country during the flu season.
    The level of risk depends on the traveller's general health, time of year, destination and duration of travel. Crowded conditions or     attending events with large gatherings, travelling on cruise ships or joining large commercial tours, may increase your chance of getting the     flu.
    People over 65, young children (six months to five years), children and adults with chronic conditions like asthma, diabetes and cancer, and     pregnant women are more likely to become seriously ill.
How is it transmitted?
The flu is spread through droplets in the air when someone who is already infected coughs or sneezes. It can also be spread by touching objects and surfaces that have been contaminated by the virus.
What are the symptoms?
    Cough and fever, and may also include headache, chills, loss of appetite, muscle aches, fatigue, runny nose, sneezing, watery eyes and     sore throat.
    Nausea, vomiting and diarrhea may occur in children
    In more severe cases, complications such as pneumonia may develop, especially for those at higher risk

Most people recover from the flu within 7 to 10 days.

Where is Influenza (flu) a concern?
The flu occurs worldwide. 
In the northern hemisphere the flu season usually runs from November to April. There may still be occasional cases or outbreaks at any time of the year.
In the southern hemisphere the flu season is between April and October.
In tropical countries, the flu is a concern year round.
Recommendations
Consult a health care provider or visit a travel health clinic preferably six weeks before you travel.
Get vaccinated. This is the most effective way to protect yourself from the flu. The flu shot can prevent illness in about 70% to 90% of healthy people. Full protection from the flu takes about two weeks from the time you are vaccinated and lasts six months.
