A mosquito-borne arbovirus, O’nyong’nong virus (ONNV) is an acute febrile illness w/HA, large joint pains, +/- rash & LAD.
It was identified in 1959 but remains relatively rare, partially due to limited diagnostics. These are the 1st reported Nigerian cases… #IDSky

Another #Marburg vaccine💉candidate originated in Canada's National Microbiology Lab 20yrs ago (alongside the 1st #Ebola vaccine).
It's only now approaching clinical trials c/o IAVI w/ US BARDA funding.
Will the new HERC agency, described as Canada's BARDA, better support Cdn innovation end-to-end?
