Venezuela’s political and economic crisis has fostered conditions favorable to communicable disease outbreaks, including measles, malaria, and HIV. We call attention to the spread of these diseases in Venezuela, and we examine the evidence of regional transmission.
Globally, measles are on the rise. This post outlines two outbreaks from this past year, one in the Ukraine and the other in Madagascar. Both of these outbreaks illustrate how low vaccination coverage can lead to high case numbers.
A measles outbreak centered in Clark County, Oregon has already resulted in cases in two other states, including Hawai’i. This outbreak illustrates the risks posed by pockets of low vaccination coverage and the intense effort required to complete contact tracing for such a highly transmissible infection.
In addition to high-profile measles outbreaks, other vaccine-preventable diseases, including chickenpox, are making a comeback. An ongoing outbreak in North Carolina highlights the risks posed by low vaccination coverage in children.
Europe is reporting a record high number of measles cases for the first six months of 2018. We explore which European nations have been hardest hit, and we examine the potential role of the European political climate in exacerbating the outbreak.
Even small outbreaks can have substantial financial costs, far beyond the cost of health care for the patients, which can be a major burden to health departments.
UPDATED 6/22/2018: PAHO announced that genetic sequencing detected neither wild nor vaccine-derived poliovirus in samples from the acute flaccid paralysis patient in Venezuela.
After cutting global measles incidence from 2.6 million to fewer than 100,000 cases per year globally, measles may be on the rise due as a result of low vaccination coverage.
