OBJECTIVES: Rising global temperatures are expected to increase time individuals spend in under-ventilated spaces and to increase transmission of respiratory pathogens. We studied the impact of ventilation on transmission potential and basic reproductive number (R0) of respiratory viruses in Puducherry, India.
METHODS: We measured ventilation in thirteen homes and seven healthcare offices. We applied the Wells-Riley equation to estimate the transmission potential and R0 of SARS-CoV-2 and influenza under different ventilation conditions and viral shedding levels.
RESULTS: Viral transmission potential was high when doors and windows were closed and highest in the air conditioned (AC) condition. Transmission potential decreased significantly with natural ventilation. R₀ equaled or exceeded 2 in the closed and AC conditions for medium and high virus shedders.
CONCLUSION: The transmission potential of respiratory viruses in underventilated homes and healthcare spaces is high, particularly with AC use. Natural ventilation does not reduce R0 below 1 for super shedders.
