Epidemiology and Economic Burden of Chikungunya: A Systematic Literature Review.

Chikungunya (CHIK) is a re-emerging viral infection endemic in tropical and subtropical areas. While the typical clinical presentation is an acute febrile syndrome, long-term articular complications and even death can occur. This review characterizes the global epidemiological and economic burden of chikungunya. The search included studies published from 2007 to 2022 in MEDLINE, Embase, LILACS, and SciELO for a thorough evaluation of the literature. Rayyan software was used for data analysis, and data were summarized descriptively and reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Seventy-six publications were included. Chikungunya is widely distributed in the tropics, including Africa, Asia, South America, and Oceania/the Pacific Islands, and co-circulates with other simultaneous arboviruses such as DENV, ZIKV, and YFV. Chikungunya infection can lead to chronic articular manifestations with a significant impact on the quality of life in the long term. In addition, it generates absenteeism and economic and social losses and can cause fatal infections in vulnerable populations, mainly in high-risk patients with co-morbidities and at the extremes of age. Reported costs associated with CHIKV diseases are substantial and vary by region, age group, and public/private delivery of healthcare services. The chikungunya disease burden includes chronicity, severe infections, increased hospitalization risks, and associated mortality. The disease can impact the economy in several spheres, significantly affecting the health system and national economies. Understanding and measuring the full impact of this re-emerging disease is essential.

Dentistry vs Severe Acute Respiratory Syndrome Coronavirus 2: How to face this enemy / Odontologia vs Síndrome Respiratória Aguda Severa Coronavirus 2: Como enfrentar o inimigo

ABSTRACT Since the beginning of the SARS-CoV-2 pandemic, numerous restrictive measures have been taken by the governments of different countries. Recently, due to the high possibility of transmission in dental offices, there was a recommendation by the American, European and Brazilian governments to request the closing of the offices. In this commentary, we will give an overview of the reasons and perspectives of this scenario.
