Clearly, public health officials have limited control over the virus. Brazil’s own experience mirrors the global one with mosquito-borne diseases – they tend to become endemic. But there is some positive news: Zika is milder than the diseases it most closely resembles—dengue and chikungunya. Roughly three quarters of those infected simply develop flu-like symptoms, which last about one week, while the remainder are asymptomatic (though speculation abounds that there may be congenital effects from the infection, which if true, would have meaningful long-term economic and social consequences).This suggests that the potential for Zika-related social and economic dislocation will be less than that from its mosquito-borne counterparts, and that the associated workplace absenteeism and barriers to productivity should be bounded.

However, with past as prologue, the short-term impact will be pronounced. Although Zika has primarily hit relatively poor and underdeveloped northeast Brazil, its appearance in prosperous hubs such as Rio de Janeiro and Sao Paulo will likely drive down domestic consumption and tourism. Indeed, a key difference in this case, compared to illnesses like Ebola and MERS, is that Zika does not appear to be transmissible person to person. Therefore, whatever negative effects there might be on retail, indoor entertainment, and on workplace and school attendance will likely be short-lived, as the climate of fear associated with an unfamiliar threat subsides. Brazil’s impending winter will also help, as falling temperatures impede the spread of mosquito-borne diseases during the country’s colder, drier months.

Tourism, however, will take longer to rebound, as it did after the MERS outbreak in South Korea last year, and the Severe Acute Respiratory Syndrome epidemic in the early 2000s. This could be particularly problematic given the upcoming Carnival celebration in February and the 2016 Olympic Games in August, events that are significant not only for the revenues and reputational benefits they might confer to Brazil’s ailing economy, but also for their potential to exacerbate Zika’s foothold in the country—as any mass gathering can.

Brazilian officials are in an exceedingly difficult and unenviable situation. The current health minister, Marcelo Castro, a political appointee with only four months on the job, appears to lack the technical credentials to steer the country’s epidemiological response (though the problem admittedly predates his tenure). Perhaps more disconcerting, however, is the tone of his public statements on the matter, which have been aptly categorized by a senior World Health Organization (WHO) official as “fatalistic.” If there is anything to be learned from the tragedies that unfolded in West Africa during the Ebola outbreak, it is that consistent, constructive risk communication is vital to managing public health emergencies. The Rousseff administration likely recognizes this, and will probably repackage its messaging in short order.

Brazil’s institutional capacity to manage outbreaks is promising, particularly relative its Latin American peers. The government has a number of credible institutions, such as the Oswaldo Cruz Foundation, working on characterizing Zika and its epidemiology. Moreover, a robust community health network—under the aegis of the Family Health Strategy—is capable of sharing guidance on behavioral changes that can temper the spread of Zika at the community level. Still, widespread containment efforts could be hamstrung by the government’s acute fiscal constraints—particularly if a linkage is established between Zika and congenital defects, and if the government needs to double down on developing and/or deploying both preventive and therapeutic interventions.

Regional and international bodies will have a hand in Brazil’s outcome, too. To wit: in the 1950s, Brazil successfully eradicated the mosquito that carries Zika, dengue, and chikungunya, only for the mosquito to reemerge, presumably due to inbound travel from neighboring countries. While technical assistance from the U.S. and the EU will carry some benefits, one global actor has been conspicuously quiet for the most part: the WHO. Specifically, members of the global health community are rightly puzzled as to why the multilateral agency took so long convene an emergency committee to address Zika, as the virus is poised to spread throughout the Americas. Doing so would not only help marshal resources, but also set the tone for the development of best practices for managing the virus, including those associated with trade and travel restrictions. In the absence of such guidance, countries are more likely to unilaterally impose commercial restrictions, such as advising against travel to Brazil during the summer Olympics. The attendant patchwork of approaches to reining in Zika would undoubtedly spell trouble for Brazil as it strives to stabilize its economy.
