Measles outbreak: preliminary report on a case series of the first 8,070 suspected cases, Manaus, Amazonas state, Brazil, February to November 2018.

We report an ongoing measles outbreak in Manaus, Amazonas state, Brazil. As at 3 November 2018, 1,631 cases were confirmed corresponding to an incidence of 75.3 per 100,000 inhabitants; all five sanitary districts presented confirmed cases. Reintroduction of measles virus in Manaus is likely related to the current outbreak in Venezuela and due to recent decline in measles vaccine coverage. Given the current scenario, prevention and control measures should target individuals aged 15-29 years. PMID: 30646975 [PubMed - in process]

Measles, mumps, and tuberculosis—these are all diseases the general public has long disregarded as active threats. Yet, these highly infectious and potentially life-threatening diseases once considered eradicated have been resurfacing across the United States. Measles, for example, was declared eliminated in 2000 by the CDC, yet this year alone more than 1,200 individual cases have been confirmed in 30 states. This outbreak represents the greatest number of reported cases for the disease in the United States since 1992.1 While the ongoing anti-vaccination movement may not be the cause of these reappearanc...

  The topic of childhood vaccination has become increasingly tendentious in recent years.  While ‘vaccine hesitancy’—a term that encompasses a wide range of attitudes, from those who have some misgivings about vaccination to those who refuse all vaccinations for their children—has existed ever since Edward Jenner developed the smallpox vaccine in 1798, many point to a now retracted 1998 paper in The Lancet as the origin of today’s particular brand of vaccine hesitancy. In the United States, there are three ways by which a child can be exempt from vaccination.  State laws differ ...

PorcoAbstractA large measles outbreak in 2014–2015, linked to Disneyland theme parks, attracted international attention, and led to changes in California vaccine policy. We use dates of symptom onset and known epidemic links for California cases in this outbreak to estimate time-varying transmission in the outbreak, and to estimate generation membership of cases probabilistically. We find that transmission declined significantly d...

CONCLUSIONS: A small set of anti-vaccine advertisement buyers have leveraged Facebook advertisements to reach targeted audiences. By deeming all vaccine-related content an issue of "national importance," Facebook has further the politicized vaccines. The implementation of a blanket disclosure policy also limits which ads can successfully run on Facebook. Improving transparency and limiting misinformation should not be separate goals. Public health communication efforts should consider the potential impact on Facebook users' vaccine attitudes and behaviors. PMID: 31732327 [PubMed - as supplied by publisher]

Abstract In the U.S., measles, mumps, and rubella vaccination is recommended as two vaccine doses. A third dose of measles-mumps-rubella (MMR) vaccine is being administered in certain situations (e.g., identified seronegativity and during outbreaks). We studied rubella-specific humoral immunity (neutralizing antibody, enzyme-linked immunosorbent assay/ELISA IgG titer and antibody avidity) and the frequencies of antigen-specific memory B cells before and after a third dose of MMR-II in 109 female participants of childbearing age (median age, 34.5 years old) from Olmsted County, MN, with two documented prior MMR v...
