I am trying to understanding what is required " Identify one trend in global health and discuss how this trend may affect public health in your community." Am I right by thinking that this like how prevention of hiv by cdc can affect local communities. I am trying to understand what is required.
Your example is correct.
Since the assignment concerns global health, you might want to research the work that the World Health Organization does.

Are there any of the issues addressed by WHO that affect your community?
Yes, you are on the right track! The task is asking you to identify a trend in global health and then discuss how that trend could impact public health in your community.
To get started, you would first need to research and identify a trend in global health. For example, a current trend in global health could be the increasing prevalence of non-communicable diseases (such as heart disease, diabetes, or cancer) due to lifestyle and behavioral choices.
Once you have identified a trend, you can then analyze how it might affect public health in your community. Using your example, if you choose to discuss the trend of HIV prevention by the CDC, you could discuss how improved prevention efforts and access to treatment could lead to a decrease in HIV transmission rates in your community. This could result in improved public health outcomes such as lower rates of new infections, increased life expectancy for individuals living with HIV, and reduced healthcare costs associated with treating HIV/AIDS.
Remember to support your discussion with evidence, such as statistics or research findings, to make your argument stronger.
