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.
