Zika virus cases skyrocketed from 103 just before the quake to 1,275 confirmed cases in Ecuador 10 weeks after the disaster, with 86 percent of all new cases occurring near the Manabi epicenter
A public health study has found a link between psychological distress and people experiencing Zika-like symptoms in areas hardest hit by Ecuador’s 2016 earthquake, particularly among women between the ages 40 and 60 years.
The city of Bahia de Caraquez in Ecuador’s Manabi province was rocked by a 7.8 magnitude earthquake on April 16, 2016. The region’s weak infrastructure and lack of preparedness resulted in high rates of mortality and morbidity and significant damage to buildings, roads and water supply.
At least 660 people died, with a further 30,200 displaced and 720,000 left in need of humanitarian assistance. More than 9,700 buildings were reported damaged or destroyed.
Survivors were forced to sleep outside in makeshift tents and store water in open tanks, placing them under increased psychological stress.
A joint study by the Ecuadorian Department of Health; the SUNY Upstate Medical University in Syracuse, NY; and the University of California San Francisco in Sacramento concludes the conditions caused a spike in incidents of the Zika virus and other vector-borne diseases, such as dengue fever.
Zika virus cases skyrocketed from 103 just before the quake to 1,275 confirmed cases in Ecuador 10 weeks after the disaster, with 86 percent of all new cases occurring near the Manabi epicenter.
Scientists, led by Anna Stewart-Ibarra, director of the Latin American Research Program for the Center for Global Health and Translational Science at SUNY Upstate Medical University, found that nearly 10 percent of interviewees suffered from a variety of Zika virus or dengue fever symptoms. Of those, more than 58 percent were suffering fear or anxiety.
The study, published in the International Journal of Environmental Research and Public Health, concludes that women between 40 and 60 years old still not sleeping in their own homes three months after the quake reported the highest incidences of Zika symptoms and mental distress.
Middle-aged women shoulder the most responsibility for their families in Ecuador, the study found, with female community leaders feeling doubly responsible to care for their neighbors. These social factors, along with the environmental conditions, likely decreased the ability of their immune systems to fight off the virus.
Director Stewart-Ibarra told teleSUR: “The earthquake in Ecuador triggered PTSD [post-traumatic stress disorder], lowering people’s immune systems because of stress.”
She said very few researchers are “looking at how mental health and infectious diseases interact in post-disaster settings.”
She also noted that such studies, of which there are very few, are important because “we see more and more extreme natural disasters, especially climate-related natural disasters.”
