Vector-borne viruses, transmitted among humans and animal hosts through bites of vectors such as mosquitoes and ticks,pose a great and ongoing threat to public health and biosafety(Yang et al., 2022).Among them, dengue virus-induced epidemics, have dramatically increased worldwide in recent decades. The report released by the World Health Organization(WHO) at the end of 2023 showed that dengue epidemic globally surged in2023, with the number of reported cases nearing a historical peak.

AIM To determine if our health system's integrated model reflects sustained virologic response(SVR) outcomes similar to those in clinical trial data, maximizes adherence, and averts drug *** Subjects with chronic hepatitis C had their medical records reviewed from November 1st, 2014 through March 1st, 2016. Patients eligible for treatment were entered into an integrated care model therapy algorithm. The primary outcome was SVR12 based on intention to treat(ITT) analysis. Inclusion criteria consisted of both treatment na?ve and experienced patients over the age of 18 who were at least twelve weeks post-therapy completion with any genotype(GT) or METAVIR score. Secondary outcomes included adherence, adverse events, and number of drug interaction *** At the time of analysis, 133 patients had reached twelve weeks post therapy with ITT. In the ITT analysis 70 patients were GT 1a, 26 GT 1b, 23 could not be differentiated between GT 1a or 1b, 8 GT 2, 4 GT 3, and 2 patients with multiple genotypes. The ITT treatment regimens consisted of 97 sofosbuvir(SOF)/ledipasvir(LDV), 8 SOF/LDV and ribavirin(RBV), 7 SOFand Simeprevir(SMV), 6 3D and RBV, 1 3D, 11 SOF and RBV, and 1 SOF, peg interferon alpha, and RBV. The overall SVR12 rate was 93% in the ITT analysis with a total of 6 patients relapsing. In patients with cirrhosis, 89% obtained SVR12. All 33 patients who were previous treatment failures achieved SVR12. Drug-drug interactions were identified in 56.4% of our patient population, 69 of which required interventions made by the pharmacist. The most common side effects were fatigue(41.4%), headache(28.6%), nausea(18.1%), and diarrhea(8.3%). No serious adverse effects were *** Dean Health System's integrated care model successfully managed patients being treated for hepatitis C virus(HCV). The integrated care model demonstrates high SVR rates amongst patients with different levels of fibrosis, genotypes, and HCV treatment histo
