Introduction: Chronic cough is defined as a cough that lasts longer than 4 weeks, and it is estimated that it accounts for 5% to 10% of pediatric pneumology visits. In 2018, the WHO reported more than one million cases of tuberculosis in children, with a mortality of 14%. However, this disease is not included on the chronic cough algorithms and its diagnosis may be challenging due to the paucibacillary of the cough in children and the variability of the clinical presentation Justification: At the moment, there doesn’t exist a chronic cough differential diagnosis algorithm in Peru which is adapted to the diagnosis of pediatric tuberculosis despite the fact that this disease represents a high public health cost and use of medical services, likewise an early diagnosis of tuberculosis is associated with a decrease in long term complications. Methods: A transversal analytical study was carried out using the clinical histories collected as non-probabilistic sampling using consecutive census-type cases that had cough for more than 4 weeks as primary symptom in the year 2019. The prevalence ratio was calculated according to the Poisson. Results: 220 patients with a median cough of 6 weeks (IQR 4-12) were analyzed. The median age was 3.75 years (IQR: 1.92 to 6.29) and 73 (60.8%) patients were male. The history of epidemiological contact had a PR of 3.08 (95% CI 1.23-8.38, p=0.016). Weight loss had a PR of 3.06 (95% CI 1.12-8.38, p = 0.03) and presenting a positive PPD test increased by 2.71 times (95% CI 1.67-24.03, p=0.007) the probability of having tuberculosis in the population studied. Conclusions: Weight loss and epidemiological contact were associated with the diagnosis, as well as positive PPD. However, studies on a larger scale and with diverse populations are necessary for the development of a standardized guide.
