[Leish-l] infectivity or infectiousness?

[Carlos Costa]

Dear fellows,

Are there any hints on where or when to use infectivity, infectiousness or
infectiousness?
1) Talking about the host ability to transmit a pathogen.
2) Talking about the sand fly ability to transmit a pathogen
3) Talking about the pathogen ability to be transmitted.

Are they synonyms? Can we use any form in any situation?

I looked at the web but could not find anything sharp about this.

Cheers,

Carlos.
