infected individuals; J2 -infected with HIV and LTB; J3 -infected with HIV and active TB; A -AIDS patients.Graphs of the population groups vs.Time dependence for each territory were plotted.The results obtained in the SEIR model graphs of the number of HIV/TB infected and TB patients are similar to real-world data.Discussion: The study results will help predict the direction of the epidemic process HIV/TB, the number of diseased and recovered individuals in the next 3-5 years and allows estimating workload on the health system in each time period. Conclusion:The study yielded the SEIR model that can be used for short-term prediction of the epidemic of HIV/TB in the Russian territories with low TB burden.
