Low Use of Standard-of-Care Antiparasitic Drugs and Increased Estimated Outpatient Payments for Treating Schistosomiasis in the United States, 2013-19.

Drug utilization and payment estimates for standard-of-care treatment of schistosomiasis have not been reported previously in the United States. This study estimates the utilization of praziquantel (standard-of-care drug) among patients with schistosomiasis and outpatient payments among those who were treated with praziquantel, and investigates the factors associated with praziquantel use from 2013-19 using IBM's MarketScan® Commercial Claims and Encounters database. Claims data showed that only 21% of patients with schistosomiasis diagnoses were treated with praziquantel.

Low Treatment Rates of Parasitic Diseases with Standard-of-Care Prescription Drugs in the United States, 2013-2019.

To assess appropriate drug treatment of parasitic diseases in the United States, we examined the treatment rates of 11 selected parasitic infections with standard-of-care prescription drugs and compared them to the treatment rates of two more common bacterial infections (Clostridioides difficile and streptococcal pharyngitis). We used the 2013 to 2019 IBM® MarketScan® Commercial Claims and Encounters and MarketScan® Multi-State Medicaid databases, which included up to 7 years of data for approximately 88 million and 17 million individuals, respectively, to estimate treatment rates of each infection. The number of patients diagnosed with each parasitic infection varied from 57 to 5,266, and from 12 to 2,018, respectively, across the two databases.

Trends in Percentages of the US Population Covered by State-Issued COVID-19 Nonpharmaceutical Interventions, March 1, 2020-August 15, 2021.

Trends in the percentages of the US population covered by state-issued nonpharmaceutical interventions (NPIs), including restaurant and bar restrictions, stay-at-home orders, gathering limits, and mask mandates, were examined by using county-specific data sets on state-issued orders for NPIs from March 1, 2020, to August 15, 2021. Most of the population was covered by multiple NPIs early in the pandemic. Most state-issued orders were lifted or relaxed as COVID-19 cases decreased during summer 2020.

Risk factors for death and illness in dogs imported into the United States, 2010-2018.

CDC estimates 1 million dogs are imported into the United States annually. With the movement of large numbers of animals into the United States the risk of disease importation, especially emerging diseases, and animal welfare issues are of concern. Dogs that arrive to the United States ill or dead are investigated by public health authorities to ensure dogs are not infected with diseases of concern (such as rabies).

Increases in Anti-infective Drug Prices, Subsequent Prescribing, and Outpatient Costs.

This cross-sectional study examines the association of prices for drugs to treat hookworm and pinworm with prescribing and prescription-filling behaviors and total outpatient treatment costs.

The Effect of Drug Pricing on Outpatient Payments and Treatment for Three Soil-Transmitted Helminth Infections in the United States, 2010-2017.

The price of certain antiparasitic drugs (e.g., albendazole and mebendazole) has dramatically increased since 2010.

Cost effectiveness analysis of implementing tuberculosis screening among applicants for non-immigrant U.S. work visas.

Background: While persons who receive immigrant and refugee visas are screened for active tuberculosis before admission into the United States, nonimmigrant visa applicants (NIVs) are not routinely screened and may enter the United States with infectious tuberculosis.

Objectives: We evaluated the costs and benefits of expanding pre-departure tuberculosis screening requirements to a subset of NIVs who arrive from a moderate (Mexico) or high (India) incidence tuberculosis country with temporary work visas.

Methods: We developed a decision tree model to evaluate the program costs and estimate the numbers of active tuberculosis cases that may be diagnosed in the United States in two scenarios: 1) "Screening": screening and treatment for tuberculosis among NIVs in their home country with recommended U.

Economic Impact of the 2015 MERS Outbreak on the Republic of Korea's Tourism-Related Industries.

The 2015 Middle East respiratory syndrome (MERS) outbreak in the Republic of Korea (ROK) is an example of an infectious disease outbreak initiated by international travelers to a high-income country. This study was conducted to determine the economic impact of the MERS outbreak on the tourism and travel-related service sectors, including accommodation, food and beverage, and transportation, in the ROK.
