Influenza and the pandemic threat

Area of Science:

• Public Health
• Epidemiology
• Infectious Diseases

Background:

• Influenza poses a significant annual threat in Singapore, affecting 20% of the population with outbreaks lasting over 12 weeks.
• Historical pandemics, like the 1968 event, demonstrate substantial clinical attack rates and prolonged fever duration.
• Seasonal influenza results in minimal work absenteeism, contrasting with the potential severe impact of a pandemic.

Purpose of the Study:

• To outline the preparedness strategies for an imminent influenza pandemic in Singapore.
• To inform healthcare workers about the epidemiology, outcomes, and prevention of influenza.

Main Methods:

• Review of historical influenza data and pandemic impact assessments.
• Analysis of current seasonal influenza patterns and absenteeism.
• Identification of key preventive strategies for pandemic preparedness.

Main Results:

• Annual influenza affects 20% of Singapore's population; pandemic predictions indicate significant mortality and hospitalization.
• The 1968 pandemic had a 20% attack rate with fevers lasting up to five days.
• Preventive measures include public health initiatives, vaccination, antiviral therapy, and hygiene.

Conclusions:

• Effective pandemic preparedness requires a comprehensive understanding of influenza epidemiology and available interventions.
• Proactive public health measures, vaccination, and antiviral therapies are essential for mitigating pandemic consequences.
• Healthcare workers' knowledge is vital for implementing successful influenza prevention and control strategies.
