Knowledge and perceptions of Zika virus transmission in the community of Puerto Plata, Dominican Republic



Zika virus is associated with increased cases of both microcephaly and Guillain-Barré syndrome. Community knowledge, perceptions and practices to prevent infection with the Zika virus are not well understood, particularly among high risk populations living in resource-poor and Zika-endemic areas. Our objective was to assess knowledge of symptoms, health effects and prevention practices associated with Zika virus in rural communities on the northern coast of the Dominican Republic.


Study participants were contacted while attending community events such as free medical clinics and invited to be interviewed regarding their knowledge, attitudes, and perceptions of Zika virus using the World Health Organization’s Zika survey tool.


Of the 75 Dominicans that participated, 33% did not know who could become infected with Zika. In addition, only 40% of respondents were able to identify mosquitoes or sexual transmission as the primary routes of infection though 51% of respondents thought that Zika was an important issue in their community.


This study found that general knowledge regarding the basic risks and transmission of Zika were not well understood among a sample of rural Dominicans. Our findings highlight disparities in knowledge and perception of risk from Zika in rural areas compared to previous studies conducted in the Dominican Republic. Education about the basic risks and transmission of Zika are critically needed in these remote populations to reduce Zika transmission.

Peer Review reports


Once thought of as a mild illness, Zika virus and its potential complications have elicited a global public health campaign, with public health organizations such as the Centers for Disease Control (CDC), the Pan American Health Organization (PAHO), and the World Health Organization (WHO) coordinating efforts to minimize Zika virus risk and to prevent further spreading of infections [1, 2]. From January 2015 to September 2017, a total of 220,693 confirmed and 579,700 suspected cases of Zika have been reported in the Americas and Caribbean [3]. The WHO estimates there are currently 84 countries affected by the Zika virus, which has triggered strategic responses to prevent and manage complications of the Zika virus [4, 5]. Zika virus has taken on increased importance with the declaration of a Public Health Emergency of International Concern by the World Health Organization [6]. Due to the established clinical presentations of congenital Zika syndrome such as sever motor delay, functional impairments, microcephaly and Guillain-Barré syndrome, public health measures have focused on decreasing the risk of infection to pregnant women as well as women of childbearing age [1, 5, 7,8,9,10,11,12].

The virus has two known modes of transmission: via a mosquito vector and by sexual transmission [13,14,15]. The mosquito vector is thought to be the primary method for infection, though recent reports suggest that the Zika virus can survive in semen for up to 62 days after symptom onset suggesting that sexual transmission of the virus may be underestimated [6, 8, 14, 16, 17]. Accordingly, Zika infection may have long-term effects on reproductive health in addition to the neurological sequelae in newborns [18]. Sexual transmission of Zika is also concerning because sexually transmitted infections (STIs) tend to cluster geographically and occur disproportionally in areas with higher concentrations of socioeconomic disadvantage [19, 20] and limited access to sexual health resources (e.g., condoms, contraception, abortion) [21, 22]. In addition, the practice of sex tourism and partnership formation while traveling internationally (an estimated 5–50% of international travelers have sex with a new partner while abroad) raises concerns for the transmission and transportation of Zika virus to non-endemic locations, thus surveillance and preventive measures are needed in tourism hot spots—particularly in locales where prostitution is legal [23,24,25,26].

In response to the increased incidence of Zika virus infections and corresponding sequelae, the WHO released a survey of Knowledge, Attitudes and Practices (KAP) to better understand community needs and guide public health outreach [27]. Since the 2016 release of the KAP survey, it has been adapted and utilized in several Latin American and Caribbean countries [28]. Most Zika research has focused on pathophysiology, transmission, treatment and prevention. However, it is also important to understand community knowledge, perceptions and practices to determine if research findings and health education are successfully reaching at-risk populations living in Zika-endemic areas. Our objective was to evaluate the awareness, knowledge and perceived risks of Zika infection among people living on the northern coast of the Dominican Republic. This study area was selected due to the limited health education resources, high levels of poverty, Zika virus endemicity, and the high volume of tourists that frequent the area year-round.


Study population

Residents of the Dominican Republic who were aged ≥18 years who presented for free medical care or community outreach between May 10, 2017 and May 24, 2017 were eligible for this study. Potential participants were selected and approached via convenience sampling by members of the study team and invited to participate in a short survey after presenting for free optometry medical care as part of a visiting medical health outreach program or after participating in other community service outreach activities (e.g., home construction) in Puerto Plata, Dominican Republic (see Fig. 1). Approximately 10% (about 8 people) of those approached declined to participate.

After providing verbal consent, participants completed a short survey in Spanish administered by a trained study team member after they had received the aforementioned medical care or outreach services. The study team member read selected questions from the WHO’s KAP Survey to participants [27]. All surveys were conducted in private settings to facilitate genuine responses. The study team member did not read response categories to participants and allowed participants to skip questions or to respond “I don’t know” to all survey questions. The WHO KAP survey instrument is a standardized questionnaire comprised of 155 total questions, separated into four domains: knowledge, attitudes, practices and respondent demographics. The questions address both general and detailed sexual reproductive health related to Zika virus infection and practices. The survey items have been pilot tested for clarity in several languages and populations [29,30,31,32,33]. In order to facilitate completion of the survey, the survey was reduced to 41 questions addressing general knowledge such as signs and symptoms of infection (n = 5), complications and risks (n = 8), causes (n = 4), prevention (n = 9), trusted information sources for learning about Zika virus (n = 3), and demographic characteristics (n = 12) of the participants.

Statistical analysis

Responses were analyzed among those who responded to each survey question using descriptive statistics to determine the frequency (percentage) of participants selecting each survey response out of the total number of participants who answered the question. Data were analyzed using R version 3.4.0.


Characteristics of the 75 study participants are presented in Table 1. More than half (64%) of the respondents were women and mean age was 42 years, with a range from 18 to 84 years. In general, respondents had low levels of formal education (52% with less than middle school educational attainment), reported low incomes [mean annual income 13,243 Dominican pesos (approximately $300 US dollars)], and were from impoverished small rural communities (known as bateyes) along the coastline.

Table 1 Characteristics of study participants in the Dominican Republic (n = 75)

General Zika knowledge was low in this study population (Table 2). Notably, one-third of the respondents did not know who could become infected with Zika, and 40% did not know how Zika was contracted. Only 40% of respondents were able to identify mosquitoes or sexual transmission as the primary routes of infection. However, 51% of respondents thought that Zika was an important issue for their community, with the major reasons cited for concern being that they would become sick (40%), followed by babies being born with disabilities (19%), and a fear that Zika is contagious (9%). Many participants were not able to identify risks caused by Zika for babies in the womb (39%), and only 9% mentioned microcephaly.

Table 2 Responses to questions regarding general knowledge about Zika (n = 75)

Zika prevention knowledge and uptake of Zika prevention behaviors were also low (Table 3). The vast majority (88%) thought that Zika could be or ‘maybe’ could be prevented. However, 31% of participants did not know how to prevent Zika. The most commonly reported methods to prevent Zika were cleaning the household environment (33%), using mosquito nets (28%), and using mosquito repellent (13%). Over half (55%) of the participants had not taken any action to prevent Zika although they had heard of Zika. Among the 34 participants who had taken actions to prevent Zika, the most commonly reported actions were using mosquito nets (47%), using mosquito repellent (35%), and drinking clean water (27%). When asked how participants would like to receive more information about Zika, 45% reported they would like to hear directly from a medical professional and 72% reported that they would ask a medical profession directly if they had any questions about Zika.

Table 3 Responses to questions regarding prevention of Zika infection (n = 75)


This study found that general knowledge regarding who can contract Zika, how the virus is transmitted, and what symptoms manifest after Zika infection was low among a sample of Dominicans on the northern coast of the Dominican Republic. Our findings differed from those obtained by the Pan-American Health Organization, which used the same WHO KAP Survey to interview 608 Dominicans in and around the capital city of Santo Domingo. For example, in Santo Domingo, it was reported that approximately half of participants (51% of men and 47% of women) identified mosquitos as the cause of Zika, and two-thirds of participants (67% of men and 64% of women) were able to identify that anyone could contract Zika [34]. In contrast, in our sample, which was conducted among rural and less educated Dominicans, only 37% of participants were able to identify mosquitos as a cause of Zika and only 51% were able to correctly identify that anyone could be at risk for Zika. Furthermore, several participants reported inaccurate Zika transmission routes (contaminated water, 22.7%; poor hygiene, 10.7%; or a dirty environment, 8%) and prevention practices (e.g., 26.5% reported drinking clean water to prevent Zika infection). The observed differences in knowledge about Zika in these very different Dominican populations suggest that rural areas, where there is less accessibility to medical specialists, education and preventive tools, may be at greater risk for Zika infection. The perception of risk has a significant influence on health behavior [35,36,37,38], thus knowledge of Zika transmission mechanisms and personal infection risks are crucial for people to make the necessary behavioral changes to reduce their risk of infection.

Tourist-attracting nations, such as the Dominican Republic, could play a significant role in global transmission of the Zika virus [17, 37, 39]. For example, from January 1, 2017 to September 20, 2017, 98.5% (264/268) of Zika cases in the United States occurred in travelers returning from infected areas [40]. A survey conducted in New York in 2016 revealed that nearly one-third of pregnant women who had traveled to high-risk Zika locations were unaware of governmental travel advisories to restrict travel to these locations [41]. Other studies have also indicated low knowledge about Zika virus among travelers to Zika endemic locations [42, 43]. Hence, issuing travel advisories without effective education and notification to travelers regarding the risks, transmission pathways and prevention techniques for Zika are not sufficient alone. The need for comprehensive education and widely accessible information regarding potential disease risks, particularly for pregnant women and individuals practicing sex tourism, is needed to reduce and prevent Zika transmission in residents of the Dominican Republic and travel-acquired cases of Zika virus in non-residents.

Our findings revealed very low knowledge of the sexual transmission of Zika and consequences of infection during pregnancy in our study sample. In particular, our results differ from a study conducted among 526 Brazilian women, which found that 50.2% were aware of the sexual transmission of Zika and 98.6% knew that Zika was associated with congenital defects in newborns [44]. In the present study, only one women correctly identified that Zika could be transmitted sexually, while only 5 women (10.4%) were aware of the association between Zika and microcephaly. This finding is concerning given that the interviews were conducted several months later than those in Brazil, nearly an entire year after the CDC stated that Zika was associated with microcephaly [45] and more than 1 year after the CDC published guidelines to prevent sexual transmission of Zika [46]. Additionally, our findings show that only one person (2.9%) in our sample used condoms to prevent the spread of Zika. In a separate study conducted in rural Dominican communities, 93% of women were found to be aware of Zika but this awareness did not impact their contraceptive usage [47]. These differences indicate that there is notable variation in Zika knowledge across Dominican communities which may be a result of inaccessibility of medical services and products, such as contraceptives [47].

The majority of study participants reported being most comfortable receiving Zika-related information from medical professionals. The Dominican Republic, like many low- and middle-income countries, suffers from a shortfall of trained medical doctors. Most recent estimates indicate there are only 1.5 physicians per 1000 Dominicans [48], and residents of poor batey communities, like those enrolled in our study, are among those least likely to have to access medical care. Despite these challenges, there is precedent for successful dissemination of health information in rural Dominican Republic in the face of new disease outbreak. In 2010, a cholera epidemic began in neighboring Haiti and threatened to spread extensively across the border to the Dominican Republic [49]. Mass media messages, distribution of classroom booklets, and home visits from community health workers were largely credited with minimizing the impact of cholera in the Dominican Republic [50]. It is likely that a similarly multifaceted educational campaign would be effective at spreading accurate and actionable Zika-related health information.

This study has several limitations. First, generalizability of these study results is limited by convenience sampling among members participating in health and community outreach activities in these small rural communities. Second, there is opportunity for selection bias since this population was recruited during these communal activities and among impoverished individuals. For example, the study population may be more involved, aware, and connected to the community and therefore may have better awareness of Zika than the average community member. Furthermore, the recruited population is likely to have higher rates of poverty since they were seeking free medical care and other outreach services. Third, the small sample size of the study (n = 75) limited the precision with which we measured our descriptive statistics. Fourth, the KAP Survey does not capture knowledge of vertical transmission. Future studies should address knowledge and awareness of vertical transmission [51,52,53]. Fifth, the study data are self-reported and may be subject to recall bias. However, this study used the same survey instrument used by international agencies such as WHO and PAHO and, therefore, results can be directly compared to similar surveys conducted among various populations. Future research should be conducted in order to further illuminate the knowledge of Zika among rural Dominicans, a population that is likely to be highly affected by the virus and harder to reach by traditional means of health communication and prevention education.


Measuring and increasing knowledge of Zika risks and transmission in communities, especially those where Zika is endemic, is of great public health significance. This study provides guidance for the future development of health interventions and messaging for this rural population in the Dominican Republic. Specifically, we found that information regarding the basic risks and transmission of Zika are not well understood in these impoverished and remote populations and more education and outreach are needed.
