Weiner, Kar MuthumaniAbstractVaccines are considered one of the greatest advances in modern medicine. The global burden of numerous infectious diseases has been significantly reduced, and in some cases, effectively eradicated through the deployment of specific vaccines. However, efforts to develop effective new vaccines against infectious pathogens such as influenza, Human immunodeficiency virus (HIV), dengue virus (DENV), chikungunya virus (CHIKV), Ebola virus, and Zika virus (ZIKV) have proven challenging. Zika virus is a mosquito-vectored flavivirus responsible for periodic outbreaks of disease in Africa, Southeast Asia, and the Pacific Islands dating back over 50 years. Over this period, ZIKV infections were subclinical in most infected individuals and resulted in mild cases of fever, arthralgia, and rash in others. Concerns about ZIKV changed over the past two years, however, as outbreaks in Brazil, Central American countries, and Caribbean islands revealed novel aspects of infection including vertical and sexual transmission modes. Cases have been reported showing dramatic neurological pathologies including microcephaly and other neurodevelopmental problems in babies born to ZIKV i...

With cases rising in Florida, Singapore, Vietnam and Trinidad and Tobago, the Zika virus pandemic is raising public concern in regions across the globe, including the U.S., where about 80 percent of Americans are aware of it but only 40 percent understand how it is actually transmitted. This raises a host of questions not only about the clinical and epidemiological scope of the outbreak, but also about the ability of citizens, public health authorities and politicians at all levels to adequately deal with it.  So far, the response has been slow and the challenge remains serious and unpredictable. We need to understand...
