BIOL 5505A Global Challenges for the Health Services Professional: Where to start? Search strategy



Step 1

What are the key words? 

Environmental factors. What are effects of global warming on infectious diseases?

Key words:     Global Warming, Infectious diseases

Key words are natural language terms, that is spoken language terms

We are going to use Boolean operators AND, OR, NOT, to combine our key words in some meaningful way to retrive most relevant articles on our topic from the literature.

Global warming OR climate change OR extreme weather incidents.

Most databases you can use truncation. Example

Glob* Warm* OR Climat* Chang* OR Extreme weather incident*

The next key word or concept is Infectious diseases

So again we are going to use synonyms or related trems with an OR in between.

Infect* disease* OR Emerging infect* disease*

Step 2: We use AND to combine the two concepts in a search statement:

(Glob* Warm* OR Climat* Chang* OR Extreme weather incident*) AND (Infect* disease* OR Emerging infect* disease*)

Step 3: Do a search in PUBMED. Look at subjects the article is indexed under.

Step 4: Download full text of articles.
