Thanks Paul
Since R0 will help in quantification of transmissibility of the
PPR virus from an infected animal to susceptible population in a given
geographic location and will guide appropriate intervention including but not
limited to stamping out and or ring vaccination therefore I strongly suggest calculation
of R0 in different geographic locations. I learnt while working in SAARC region
that sharing of data is sensitive for the countries however they can share the results
in the form of publication and or periodic reports. So I personally feel that developing
guidelines/SOPs by this forum would be useful in harmonizing the R0 calculation
method (s) at regional / national level to understand the dynamics of this
disease in space and time.
Lets see what others say!

Subject: From Dr Muhammad Akram a fundamental question on PPR
epidemiology . Plus moderator's comment.
Dear Colleagues,
I really enjoyed very hot discussions on vaccine and vaccine
coverage that lead me to put a question to the forum: "As to what is herd
immunity for PPR and its implication to vaccine coverage and has any one worked
on estimation of basic reproduction number (R0) and or effective reproduction
number (Re) of PPR epidemics"?
I think answers to these question will help us in proceeding
further in the PPR control/ eradication.

One or two contributors have touched on
this. I don't think we have calculated R0 for PPR yet
but I know thatsome research groups may have either started or
are planning to work on this. My question to you and other participants is
"Could a network, such as the proposed PPR-GREN we are exploring
together, be a forum in which we could develop guidelines/operating
procedures for collecting and sharing the kind of data needed to calculate
R0 in a number of different locations globally? It would be
exciting if we could work together like this. - Moderator.
