West Nile virus (WNV) is the leading cause of domestically acquired arboviral
disease in the continental United States (1,2).
The rising temperature has paved way for many arboviral
diseases to arise especially dengue and malaria and as of recent times, Chickungunya.
SAN DIEGO -- When compared with pretravel blood screening, new arboviral
infections were detected in 7% of U.
Correct diagnoses improve the ability of public health ministries to detect and react to outbreaks of DENV or other arboviral
illnesses, rather than contributing to cycles of missed opportunities for preventive interventions.
Dengue as we all know is a serious arboviral
disease and it has very uncomfortable symptoms and has become more serious both in frequency and mortality in recent years.
In December 2013, the arboviral
disease panorama in the Western Hemisphere changed forever with the first reported indigenous circulation of the chikungunya virus in the Region of the Americas, on the island of Saint Martin (1).
However, the similarity with other arboviral
diseases makes its real incidence unknown.
Since February 2016, the CDC has been relying on data from the national arboviral
disease surveillance system (ArboNET) to track Zika in pregnant women with symptoms of the Zika virus infection, or those with pregnancy complications consistent with the virus.
The analysis included specimens that were received for testing at the CDC Arboviral
Diseases Branch and confirmed Zika virus infection was defined as detection of Zika virus RNA by reverse transcription-polymerase chain reaction, or anti-Zika immunoglobulin M antibodies by enzyme-linked immunosorbent assay with neutralizing antibody titers against Zika virus, at levels greater than or equal to fourfold higher than those against dengue virus.
The April 2014 Morbidity and Mortality Weekly Report article "National Capacity for Surveillance, Prevention, and Control of West Nile Virus and Other Arbovirus Infections" describes how the national arboviral
surveillance infrastructure built for WNV response was compromised by a 61-percent decrease in Epidemiology and Laboratory Capacity grant funding from 2004 to 2012.
Because of suspicion that cases were being missed by an assay in use at the time in Minnesota, which had relatively poor sensitivity for detecting Jamestown Canyon virus, an enzyme immunoassay specific to JCV was put into use in 2014 to test serum and cerebrospinal fluid specimens submitted for other arboviral
underscores the risks posed by this and other exotic pathogens," said Roger Nasci, PhD, chief of the Centers for Disease Control and Prevention's Arboviral
