Are studies disappearing?

I swear I read a case study last week on a person who contracted bird flu through no typical transmission routes. It was hypothesised that they caught it through breathing in the feces of an infected animal during high winds. Sounding alarms about the possibility of airborne transmission.

I was attempting to find the case study today, I can’t find it. I didn’t download the PDF or print it or anything sadly. Actually, it seems searches for academic papers and case studies on the bird flu are coming up with less and less results.

Before I start freaking out, are papers disappearing or am I just going crazy??
