Help with question
Hi, everyone
Should you say "The country is facing both a Zika and (a) dengue crisis" or "The country is facing both Zika and dengue crises"?
And "They are looking for a cure for both Zika and dengue virus" or "They are looking for a cure for both Zika and dengue virusES" or "They are looking for a cure for both THE Zika and dengue virus"
Among THESE OPTIONS, which one is right?
Thank you very much
