I hope you are doing fine. We are staring our one week panel discussion on a very important topic of TB among migrants. Today we are focusing on measuring and analyzing the burden of TB among migrants. Here we shall discuss both active and latent TB. To my view both are important. Detecting active TB is crucial to ensure early and adequate treatment and breaking the transmission cycle among migrants and avoid possible transmission from migrants to the local communities. We shall also not forget that migrants are not always having a higher TB rates than the local population, but based on the major flow of migrants, it is often the case that TB rates are higher in the country of origin than in the host country. Much less has attention has been paid to timely detection of latent TB which can avert development of the disease should a recent infection occur.
Should the receiving country have a good screening and surveillance system in place, the numerator is well reported, however most often the challenge is to know the denominator to be able to calculate the prevalence or incidence rate.
I will be posting summary of several publications today, but would like to encourage all community members and other panelists to share their views and experiences in measuring and analyzing the TB burden among migrants.
All the best,
