Introduction: The infection caused by Zika virus has had worldwide repercussion, as it has been associated with congenital syndromes in children, especially microcephaly, with an impact on public health.
Objective: To identify in the literature care actions provided by nurses to families and pregnant women to prevent and control the infection.
Method: Review study with data collected from seven databases using descriptors and Boolean operators to identify papers.
Results: The titles, abstracts and key words of 2,628 papers were read and the full texts of 39 were selected. Two papers were excluded after reading the full texts because they did not address the objective proposed here, in that they exclusively addressed the care provided to children. Another 29 papers under the original protocols and protocol update modalities were excluded. Thus, a total of eight papers remained and composed the corpus of this review.
Conclusion: The papers do not report specific actions of nurses, but emphasize pregnancy planning; development of knowledge concerning the disease and vaccine; the delivery of health care and social support to the families with children presenting permanent special needs accruing from the Zika virus disease; and the report of suspected and confirmed cases.

Isolated over 70 years ago in Uganda in the Zika Forest, on the Entebbe Peninsula in 1947 by scientists who studied the yellow fever virus in Rhesus monkeys? The Zika virus (ZIKV) is an arbovirus of the Flavivirus genus of the Flaviviridae family . In 2015, the Brazilian authorities attributed a 20-fold increase in the number of new borns with microcephaly to the ZIKV virus .
Brazil is a country with hot and humid weather. It states present poor environmental structure, among which are inappropriate water supplies and open sewers that work as breeding grounds for mosquitos, which favors the spread of the disease, the vector of which is Aedes aegypti mosquito [3,4].
In October 2015, the State Health Department of Pernambuco (SES/PE) reported the occurrence of 26 cases of newborns with microcephaly in different health facilities in different regions of the state. With the emergence of an increase in the number of new cases of congenital anomalies in children of mothers infected with the ZIKV in Brazil, a Public Health Emergency of National Concern (ESPIN) was declared [5,6].
The outbreak of the disease in Brazil triggered a mobilization in the technical-scientific community, society and world media. The highest incidence was observed for neurological syndromes, particularly microcephaly. Various studies and much research have been dedicated to devising vaccines, drugs, insecticides and other devices to contain and prevent the spread of infection and associated diseases. Protocols, reports, manuals, guidelines were published to disseminate knowledge among health workers and the broader society, which resulted in the establishment of partnerships among various social entities such as Centers for Disease Control and Prevention (CDC-USA), Ministry of Health of Brazil, Puerto Rico Department of Health, World Health Organization, Pan American Health Organization in order to protect the health of the population [7-13].
Nursing is a science, the essence and specificity of which is human care, that is, integral care centered on the individual, family and community. Nurses perform their practice based on scientific knowledge seeking to keep such knowledge updated in order to provide quality care .
Since 2015, the epidemic of the Zika virus in Brazil has impacted the puerperal pregnancy process, notably in terms of congenital abnormalities in children, whose mothers were infected with ZIKV during pregnancy. After the diagnostic of microcephaly was informed by the health professional the partner abandonment the family. The mothers alone needed dispense integral care that brought intense changes with economic repercussions. In general, the mother showed worry with development of children, fear of falling ill/die, and be unable to care for the child [15-17]. Amazonas, the Brazilian state with the largest territorial area, with rich biodiversity that is recognized worldwide, did not escape the repercussions caused by this virus and the stigma of the microcephaly. Taking into account the contribution of nurses to human health and development in this region, a commitment was made to conduct research addressing this topic. Considering the diversity of studies this theme requires, the following research question was established: What care actions performed by nurses for families and pregnant women to prevent and control the Zika virus disease are reported in the literature.

Data Extraction and Synthesis
Extracting and synthesizing data from heterogeneous sources is a complex process. All papers were independently assessed by two researchers. The following information was abstracted from the included studies: general information about authors, publication date, country and language, method and recommendations. Synthesis of the data involved categorizing: Educational actions/collective prevention, Actions with pregnant women, Avoid getting pregnant- before Zika virus infection and Professional advice.
A total of 29,705 papers were identified in the first consultation of the databases using the descriptor “Zika Virus”; 26,608 of these were excluded after using the filters of free access, full text, and language, employing a combination of Boolean operators, and applying inclusion and exclusion criteria. Another 469 papers were excluded because they appeared more than once; that is, the same paper was published in more than one database.
The titles, abstracts and key words of 2,628 papers were read and the full texts of 39 were selected. Two papers were excluded after reading the full texts because they did not address the objective proposed here, in that they exclusively addressed the care provided to children. Another 29 papers under the original protocols and protocol update modalities were excluded. Thus, a total of eight papers remained and composed the corpus of this review.
The synthesis described here is presented in the PRISMA flowchart Figure 1 .
Data were extracted from the papers included in the corpus of this review to compose a synthesis or analysis matrix to present a general overview of the content obtained , as shown on Table 3.

Laboratory tests seeking evidence of Zika virus infection.
Perform fetal ultrasound and refer patient to a fetal medicine service, if necessary;
Pregnant women who present no symptoms two weeks after returning from an area affected by Zika virus do not need testing.
Considering that the infection caused by Zika virus is asymptomatic in most cases, baseline fetal ultrasound is recommended within 28-20 weeks of gestation and then repeated in 28-30 weeks;
Male travelers presenting symptoms associated with the Zika virus and their pregnant partners need Zika virus testing;
Pregnant women exposed to infection caused by Zika virus whose fetuses were diagnosed with fetal microcephaly or other brain abnormalities are to be referred to a fetal medicine unit.
Amniocentesis can be performed using RT-PCR six weeks after exposure to Zika virus if the woman is ≥ 21 weeks of gestation. This procedure should be only performed after thorough counseling due to its potential complications.
Possibility to interrupt pregnancy among women infected by Zika virus and having a laboratory confirmation that their fetuses present significant microcephaly or brain abnormalities.
Midwives should work together with a multidisciplinary team and thoroughly discuss with pregnant women the risk of spontaneous abortion or stillbirth and the possibility of interrupting the pregnancy and managing newborns.

The authors present and discuss six categories:
1) How to manage nursing consultations during prenatal care in regard to suspicion of infections by the Zika virus: Follow the Women’s Health Protocol provided by the Brazilian Ministry of Health; Report suspicions of infection caused by the Zika virus to the epidemiological surveillance; Perform detailed anamnesis and physical examination; Differential diagnosis; Instruct pregnant women to seek the health unit; Perform active search through home visits, intensifying instructions and reinforcing the need for women to attend prenatal consultations; Refer women to the PNAR (High Risk Prenatal Care) if infection is confirmed.
2) Instruct pregnant women to prevent infection caused by the Zika virus:
by avoiding areas at risk; wearing long-sleeves shirts and trousers; using condoms, repellents, and window screens; and seeking the health unit in case of suspected infection caused by the Zika virus.
3) Provide guidance related to complications caused by arboviruses:
Professional qualification; gather groups of pregnant women to provide orientation; exchange experiences; establish bonds between workers-pregnant women; promote adherence to prenatal care; and provide holistic care to pregnant women.
4) Have knowledge of the complications caused by Zika virus: microcephaly; CNS is susceptible during the entire period of pregnancy; congenital malformation; hearing and vision problems; mental retardation. Complications vary among children, as there can be motor, neurological, and/or respiratory problems. Refer to specialists according to the problem presented by the child.
5) Recommendations for clinical management: classification of risk; hydration, and monitoring. The physician is supposed to establish a differential diagnosis of dengue and Chikungunya; be attentive to the risk of bleeding of an obstetrical nature associated with the risk of abortion and low-weight at birth; Pregnant women with rash be investigated whether it is caused by the Zika virus: fetal neurological assessment with a recommendation to perform two extra ultrasounds between the 20th and 24th weeks and between the 32nd and 35th weeks of gestation.
Drug treatment for the symptoms.
6) Insufficient knowledge to provide care to pregnant women with infection caused by the Zika virus:
- Continuing education;
- Training for workers to obtain new competencies: leadership, decentralized management; and self-management.
Nursing consultation during prenatal care ensures quality care, contributes to decrease maternal-fetal morbidity and mortality, preventing and identifying potential congenital malformation such as microcephaly.

Table 3. Presentation of the papers that compose the corpus of this review. Florianópolis, Santa Catarina, Brazil 2018.
Present in over 70 countries and territories, the Zika virus has become a global threat because there is an intrinsic possibility of developing neurological congenital syndrome when the infection affects women during the gestational period and presents viral persistency. Therefore, the Zika virus represents a public health problem with a global impact. There was a decrease in suspected cases of ZIKV and warn of the risk of another severe epidemic in Brazil and in other tropical and subtropical countries. For this reason, implementing preventive measures to control vector density and encourage individual and collective protection is of paramount importance [24,25].
Educational actions/collective prevention
Identifying the breeding sites of vectors is a preventive measure that favors the control of vector density, mentioned in all the papers included in the corpus analysis of this review. Notes that public health actions and the control of infection caused by the Zika virus in Brazil are related to social life and environmental conditions conducive to the elimination of the mosquito breeding sites .
Strategies to prevent and control infection caused by the Zika virus require health workers to be qualified and prepared, considering the disease is often asymptomatic. This requires attention because the infections occurring among pregnant women, and the fact there is vertical transmission, result in neurological abnormalities in fetuses and Guillain- Barre syndrome in adults . GBS is a demyelinating autoimmune pathology that causes acute or subacute flaccid paralysis . Zika epidemics are particularly worrying because infection with this virus can cause Guillain-Barre syndrome and congenital central nervous system malformations including microcephaly [27,28].
Authors consider decreasing the mosquito-to-human spread of the virus in the urban area to be related to the control of vectors by eliminating potential breeding sites for Aedes aegypti and adopting individual protection to avoid contact with the vector. Aquatic environments are water storage contexts open to the sky and small puddles are places where mosquitoes can reproduce [29-31].
In the population-based study conducted in Barcelona, the Surveillance and Pest Control Service conducted an entomological inspection in public areas and in the patient’s home. At the same time, it disseminated information concerning the areas, identifying and including areas of risk for the breeding of mosquitoes in the local Geographic Information System .
Actions with pregnant women
In the report published by the CDC on measures to prevent infection by the Zika virus during pregnancy, was mention purchasing and providing Zika prevention kits as a community intervention strategy, mainly focusing on pregnant women . The kit contains local-adapted health information, repellent, mosquito netting, condoms, and tablets to combat the mosquitoes .
The individual protection strategies included in the studies are intended to avoid insect bites in the viremic period, especially among pregnant women. For this reason, pregnant women should use safe repellents; insecticides, such as permethrin spray, on clothes; mosquito netting; light-colored long-sleeved clothing; avoid traveling to endemic areas; and use screens on windows and doors [29,32,34].
The risk of fetal congenital abnormalities is real, given that pregnant women may be infected by the Zika virus at any gestational age. Clinical guidelines to control exposure to the Zika virus during pregnancy are mainly intended to decrease the contact of people with an infected vector [29,31-32,34,35], while the following measures stand out:
▪ Clinical assessment of pregnant women returning from endemic areas with symptoms;
▪ Visiting a medical center when in an area of high prevalence of ZIKV, if showing signs and symptoms of the disease;
▪ Pregnant women with symptoms or otherwise with sexual partners traveling to outbreak areas, should practice safe sex (i.e., use condoms or refrain from having sexual intercourse);
▪ Abortion should be decided together with healthcare workers, taking into account the risk-benefit.
The clinical diagnosis of infection caused by the Zika virus is not reliable, because the disease ’ s clinical and pathological characteristics can be confused with other arboviruses. The laboratory test recommended is RT-PCR, which should be performed together with other arboviruses in patients presenting the signs and symptoms of the infection, or those exposed to areas where there is active Zika virus transmission [6,30,32,34-35].
Material for testing should be collected in the viremic period, within seven days after the onset of symptoms. Urine can be collected for up to 20 days, after which .
After obtaining a laboratory exam confirming infection caused by the Zika virus, authors recommend performing baseline fetal ultrasound. If an ultrasound reveals the fetus has a congenital syndrome arising from Zika, the patient must be referred to a fetal medicine service and/or to a high-risk prenatal care service [34,35]. According to guidelines provided by the Brazilian Ministry of Health, if an ultrasound reveals no abnormalities, pregnant women should be monitored by a high-risk prenatal care service . The Zika virus can infect pregnant women at any time during the gestational period. The first trimester of pregnancy, however, is when there is the greatest incidence of congenital malformation caused by the virus. Health providers should advise pregnant women and their families to be attentive to the risk that obstetrical bleeding may lead to the risk of spontaneous abortion, stillbirth or termination of pregnancy [34,35].
It important of decisions made at the individual and social level considering social inequality, a lack of effective vector-prevention programs, the existence of abortion-restrictive laws in some countries, difficult access to contraceptive methods and sexual education programs, that is, that decisions may be made in a context of uncertainty, which may harm the health and wellbeing of pregnant women even more, requiring high-risk ante care .
Avoid getting pregnant – before Zika virus infection
We also found in this review advice for women who are planning a pregnancy: Avoid becoming pregnant if living or traveling to a country where there is active local ZIKV transmission and eight weeks after returning home. Nurses and midwives should recommend efficacious contraceptive methods and the use of condoms for couples when at least one partner has visited an area with active Zika infection .
Actions to prevent and control the spread of the Zika virus are implemented by a multidisciplinary team in order to develop protocols. Health workers play an essential role during prenatal care by screening pregnant women suspected of being infected with Zika virus, or confirmed to be infected. The studies [6,29-32,34,35] report that the responsibilities of health workers include:
▪ Reorganize public health services;
▪ Provide pre-trip telephone counseling - Clinical guidance and preventive care during travel;
▪ Educate pregnant women, their families and the community in regard to individual and environmental preventive measures;
▪ Stay up to date;
▪ Midwives are oriented to ask questions in all prenatal consultations to all pregnant women and their partners in order to obtain information and advise on recent and planned trips;
▪ Seek the support of specialists in infectious diseases when there is suspicion of infection by the virus;
▪ Midwives should work together with a multidisciplinary team;
▪ Discuss with pregnant women about the risk of spontaneous abortion or stillbirth and analyze the possibility of interrupting the pregnancy if infection by the Zika virus is confirmed;
▪ Midwives have the responsibility of staying up-to-date in regard to local guidelines and protocols to accurately assess pregnant women exposed to the Zika virus;
▪ Provide health education to patients, community and multidisciplinary team;
▪ Early diagnosis of infection caused by the Zika virus via laboratory exam when there is a suspicion of infection;
▪ Report the infection to the agency responsible for epidemiological surveillance;
▪ Differential diagnosis of other mosquito-borne infectious diseases, such as Dengue and Chikungunya;
▪ Public health nurses must know arboviruses, specific epidemiological situation, and make appropriate records of each case;
▪ Emergency nurses should be able to recognize the signs and symptoms of infection and appropriately refer patients;
▪ Health workers such as nurses, midwives and CHAs should be aware of the neurological complications associated with the Zika virus and its social and economic impact on families and society [6,29,32,34-36].
The study carried out in the south of Minas Gerais, Brazil, and assesses the competencies of CHAs in the development of their responsibilities as established by the Brazilian Ministry of Health . Weaknesses were identified in the work performed to combat Aedes aegypti in relation to vector control. The authors mention the responsibility of nurses working in the Family Health Strategy to supervise these agents and seek scientific evidence to ground the delivery of quality care .
Neurological disorders can be diagnosed during pregnancy. The virus has a tropism to the neuronal cells at any stage of a pregnancy, affecting neuronal precursor cells, isolated in the brain tissue and cerebrospinal fluid of children with congenital syndromes . Therefore, there is a need to support research financially and establish worldwide collaboration to expand knowledge of the disease and develop a vaccine .
Note that, even though the term Zika virus originated in consultation with databases, totaling 29,705 papers, specific studies addressing the care provided by nurses to families and pregnant women and the prevention and control of this infection are still incipient. This fact should be noted because the first study addressing the Zika virus dates back to 1947, while the first outbreak occurred more than ten years ago. Thus, training nurses to observe and acquire knowledge of emergent diseases in society, as well as epidemics, is an important professional commitment that must be ethically fulfilled through education, research and dissemination of knowledge.
A small number of studies was obtained after applying inclusion and exclusion criteria, as few papers reported the care provided by nurses or nursing care provided to families and pregnant women aiming to prevent and control infection caused by the Zika virus.
The papers that compose the corpus of analysis in this review do not report the specific actions of nurses. The reports included: care in regard to the environment; individual protection of pregnant women; guidance provided to travelers; differential diagnosis in relation to other viral diseases; education provided to the nursing staff, families and pregnant women; health care and social support provided to families with children with permanent special needs arising from infection caused by Zika virus; and mandatory reporting of suspected and confirmed cases of the disease.
Considering that the professional nurse performs clinical practice in various care services is essential to participate in clinical research, especially multicenter. This will unveil new nursing techniques and technologies for the prevention and control of Zika virus infection, especially in pregnant women. As well, assess the economic and social impact of this infection.
