Abstract
WHAT IS ALREADY KNOWN ABOUT THIS TOPIC? The mortality rate due to pneumonia varies depending on the infectious agents present in a low- temperature environment. WHAT IS ADDED BY THIS REPORT? This study aimed to examine the relationship between low temperatures and cold waves and the risk of mortality from infectious pneumonia in the elderly. The findings indicate a significant increase in the risk of infectious pneumonia, specifically bacterial pneumonia, during periods of low temperatures and cold waves. WHAT ARE THE IMPLICATIONS FOR PUBLIC HEALTH PRACTICE? This study presents compelling evidence that highlights the importance of proactive public responses to infectious pneumonia among the elderly population during periods of cold waves.
