Is there a national/ international database for viruses, bacteria, fungi, etc that affect humans?

I’m imagining something like DNA held in a crime case. They can’t find a match for it so a record is kept, and vice versa if you’re convicted of a crime your DNA is now on a database for future checks. 

Now back to my original question. If you present to hospital with a cough that leaves you struggling to breathe for days on end. The staff swab you, take a sputum test, even do an endoscopy to take samples. All come back negative for anything they have “on file”. Are records of these samples kept for future testing? Do private pathology labs have access to an international or national database? If so, is it mandatory to report everything that comes into the lab?

Check out databases like NCBI's GenBank, EMBL's ENA, etc. Basically, if you have an previously unidentified disease of some fungal/bacterial origin, your doctor can work with a lab (or may have their own lab) to run a lot of tests that can identify the type of organism. They can also sequence the organism and then publish a case study on your disease, and deposit that sequence in NCBI (say) using a relatively standard procedure.
