What Is Already Known About This Topic?:
Heat-vulnerability assessment is an essential approach for identifying populations and regions that are vulnerable to extreme heat and supporting targeted climate adaptation and public-health interventions.
What Is Added By This Report?:
This study updates the national assessment to 2020; the Boruta algorithm is employed to objectively identify the indicators most strongly associated with the proportion of non-accidental deaths on extreme heat days and a revised heat-vulnerability index (HVI) is constructed.
What Are The Implications For Public Health Practice?:
The updated county-level HVI provides policymakers with a precise understanding of current heat-vulnerability patterns in China. These findings will facilitate a more effective identification of high-vulnerability regions.

Responses to Heat and Cold Stress
Assessing Body Temperature - Axilla
Step 1: Perform hand hygiene and put on clean gloves to maintain infection control and prevent cross-contamination.
Step 2: Prepare the patient by explaining the procedure to ensure understanding and cooperation. Ensure privacy, expose the axilla, and inform the patient that minimal movement is crucial for an accurate reading.
Step 3: Adjust the patient’s clothing to expose only the axilla. It minimizes...
Assessing Body Temperature - Temporal Artery
Step 1: Perform hand hygiene and don a fresh pair of gloves to prevent cross-infection and ensure patient safety.
Step 2: Explain the procedure to the patient to establish trust. Clear communication establishes trust with the patient, ensures they understand what to expect, promotes cooperation, and enhances comfort during the procedure.
Step 3: Assess the patient's forehead...
Assessing Body Temperature - Oral
Step 1:
Start by practicing proper hand hygiene to prevent the spread of microorganisms.
Step 2:
Take the thermometer out of the charging unit, switch it on, and wait for the ready sign.
Step 3:
Gently slide the probe cover until a click is heard. This simple action prevents cross-contamination and ensures the correct placement of the probe cover.
Step 4:
Instruct the patient to open their mouth and place...
Assessing Body Temperature - Rectal
Follow these steps for rectal temperature assessment:
Step 1: Perform hand hygiene and don clean gloves to prevent cross-infection.
Step 2: Position the patient in a side-lying position to better visualize the rectal...
