Identify cases for the 40-44 years age group

To find the total number of positive cases for the 40-44 years age group, we need to sum the cases for male, female, and not specified gender from the provided data.

Step 1: Identify cases for the 40-44 years age group From the data table, for the 40-44 years age group: • Male cases: 150 • Female cases: 120 • Not specified gender cases: 0

Step 2: Calculate the total number of cases Add the number of cases for all genders in this age group: $Total cases = 150 + 120 + 0$ $Total cases = 270$

The total number of positive cases for the 40-44 years age group is $\boxed{270}$.
