Dispelling the Myth: Influenza Prefers Cold Temperatures

Summer Flu
Although it occasionally makes headlines, “influenza cases soar over summer” is not the usual situation. Seasonality is a feature of influenza viruses; in temperate countries, winter is usually when they are most active. The cause of this seasonality is:

  • Climate favourable: Winter’s colder, drier weather makes it easier for influenza viruses to survive and disseminate through respiratory droplets released during sneezes and coughs.
  • Human behaviour: People spend more time indoors in close quarters during the winter, which aids in the spread of the virus.


It’s crucial to recognise that there are, in fact, exceptions.

Summer Flu: An Uncommon but Potential Case

Summer Flu
Summertime flu outbreaks are rare, although they can happen for a number of reasons:

  • certain strains: certain types of influenza A viruses, in particular H3N2, can infrequently induce summer peaks in influenza activity and show anomalous seasonality.
  • Regional differences: Influenza activity may exist year-round in areas with constant warm temperatures, such as tropical nations, but usually at a lesser intensity than in temperate zones.
  • Globalisation and travel: More people travelling around the world and being more connected to one another can spread influenza viruses, which can cause outbreaks of the virus during the off-season in temperate climates.


Remaining Alert: Safeguarding Yourself All Year Long

Summer Flu
It’s important to take precautions against influenza, no matter the season, to protect yourself and your loved ones:

  • Vaccination: The best defence against influenza infection is yearly vaccination. Everybody aged six months and older should get vaccinated annually, according to the World Health Organisation (WHO), with high-risk populations such as children, expectant mothers, the elderly, and people with long-term medical issues receiving specific recommendations.
  • hygienic procedures: The transmission of respiratory infections can be stopped by frequently washing your hands with soap and water, avoiding contact with your face, and using tissues when you sneeze or cough.
  • Healthy lifestyle: Eating a balanced diet, getting regular exercise, and getting enough sleep all help to boost your immune system and increase your resistance to illnesses.

Knowing when influenza epidemics occur and what causes them in the summer allows us to be prepared and watchful all year long. Recall that the best defence against this potentially crippling sickness is prevention for both you and others.
