Dengue is mostly considered an acute illness with three phases: febrile, critical with possible hemorrhagic manifestations, and recovery. But some patients present persistent symptoms, including fatigue and depression, as acknowledged by the World Health Organization. If persistent symptoms affect a non-negligible share of patients, the burden of dengue will be underestimated. On the basis of a systematic literature review and econometric modeling, we found a significant relationship between the share of patients reporting persisting symptoms and time. We updated estimates of the economic burden of dengue in Mexico, addressing uncertainty in productivity loss and incremental expenses using Monte Carlo simulations. Persistent symptoms represent annually about US$22.6 (95% certainty level [CL]: US$13–US$29) million in incremental costs and 28.2 (95% CL: 21.6–36.2) additional disability-adjusted life years per million population, or 13% and 43% increases over previous estimates, respectively. Although our estimates have uncertainty from limited data, they show a substantial, unmeasured burden. Similar patterns likely extend to other dengue-endemic countries.

Objectives We aimed to quantify the impact of dental caries and missing anterior teeth on employment, estimate the impact of a routine dental visit on the health of anterior teeth, and the benefits of expanding dental coverage for nonelderly adults. Methods We used the 2013–2014 Continuous National Health and Nutritional Examination Survey to develop a dental problem index (DPI) using tooth counts and tooth surface conditions. We estimated the impact of DPI on employment with logistic regression, controlling for seven demographic and socioeconomic covariates. We used a routine dental visit within 6 months as a proxy for access to dental services, and a linear regression to predict the DPI score for an average individual with and without a recent routine dental visit. We then computed the incremental probability of employment associated with a recent routine dental visit. Finally, we estimated the additional number of working age adults who might become employed due to improved access to dental services. Results The probability of being employed was negatively associated with poor oral health: a one‐point increase in DPI decreased the odds of being employed by 7.70 percent (CI: 5.15–10.19%). Having a routine dental visit had a negative and statistically significant impact on DPI [−0.41 (CI: −0.68 to −0.14)]. The incremental probability of employment associated with a routine dental visit was 0.62 percent (CI: 0.21–1.03%). Conclusions Oral health in the United States is worse among minorities and poor than among other residents. The benefits associated with access to dental care should justify expanding dental services.

Background Dengue is commonly considered an acute illness and follows three phases: febrile, critical in some cases and recovery. However, a number of studies have described a continuation of dengue symptoms for weeks or months, extending the recovery phase. Here we evaluate this persistence of dengue symptoms during convalescence. Methods Our clinical cohort study included patients who sought medical services 48 to 144 h from the onset of fever at seven hospitals or ambulatory centers in Morelos, Mexico. Seventy-nine laboratory-confirmed dengue patients were followed up regularly using clinic and/or home visits and telephone calls for as long as symptoms persisted or up to 6 mo. Results In total, 55.7% of patients had dengue-related symptoms 1 mo after the onset of fever; pain and dermatological manifestations were the most common persistent symptoms. Prognostic factors for symptom persistence were: ≥4 d of fever (RR 1.72; 95% CI 1.35 to 2.19), platelet count ≤100 000/mm3 (RR 1.20; 95% CI 1.20 to 2.20), petechiae/bruises (RR 1.97; 95% CI 1.56 to 2.48) and abdominal pain/hepatomegaly (RR 1.79; 95% CI 1.41 to 2.28). Conclusions Persistence of dengue symptoms were common in laboratory-confirmed dengue patients. Manifestations related to tissue damage were associated with persistence after 30 d; host characteristics, such as age and health status before infection, were associated with prolonged persistence (>60 d). The burden of dengue may be higher than previously estimated.

Scale up of such services is possible and encouraged because of potential health gains and reduced healthcare costs.
