Objectives At the end of this seminar student will be able to : 1. Demonstrate the definition of zika virus within 1 min. 2. List at least 3 signs and symptoms for zika virus within 2 min. 3. List the complications and transmission routes for zika virus within 1 min. 4. Give at least 3 examples of prevention ways within 1 min. 5. Recognize the diagnosis process of zika virus within 3 min. 6. Recognize some who recommendations about zika virus.
Introduction Communicable disease are caused by pathogens passed from one human to another pathogens are viral, bacterial, parasitic and fungal. Methods of transmission include mucus , blood, breath, saliva, and sexual contact. This is an examples of communicable disease : flu , Hepatitis B , HIV/AIDS , Measles , pertussis , tuberculosis and zika.
Overview of zika virus Zika virus disease is caused by a virus. The virus is known to circulate in Africa , the amiricans, asia and pacific. In 1947 , scientists studying in the zika forest near lake Victoria in Uganda isolated a novel virus in a sick monkey. There is an increased potential for indigenous transmission of zika virus in the UN because of the impending spring and summer season and the typical increase in mosquitoes in many areas ( zika virus become ) global public health crisis.
The increase in the potential indigenous transmission of zika virus serves as the impetus for efforts to educate health care providers in the assessment , treatment and education of rapidly spreading viruses.
Sign & symptoms Symptoms can last for several days to a week. People usually don’t get sick enough to go to the hospital, and they very rarely die of zika. Zika infections often begin with a headache. Within a few days patients may develop a rash, bloodshot eyes and fever. The most common symptoms of zika are fever , rash , joint pain and conjunctivitis ( red eyes ). Other symptoms include : muscle pain and headache.
Complications After comprehensive review of evidence there is scientific consensus that zika virus is a cause of : 1 - microcephaly 2 - Guillain-Barre syndrome And intense effort are continuing to investigate the link between zka virus and range of neurological disorder.
Transmission Zika virus is primarily transmitted to people through the bit of an infected mosquito from the aedes genus. Sexual transmission of zika virus is also possible. Other modes of transmission such as blood, body fluids – urine, saliva, semen -.
Prevention Protection against mosquito bits is a key measure to prevent zika virus infection. This can be done by : 1 - wearing clothes – preferably light colored – that cover as much of the body as possible. 2 - using physical barriers such as window screens of closing doors and windows. 3 - using insectrepllent – DEET, IR 3535 – 4 - special attention and help should given to those who may not to be able to protect themselves adequately such as young children the sick or elderly.
5 - travelers and those living in affected areas should take the basic precautions described above. 6 - it is important to cover empty or clean potential mosquito breeding sites in and around houses such as buckets drums, pots, gutters, and used tyres.
If the health care team provide a procedure in which there is a higher risk of exposure to body fluids, the use of mask and eye protection in addition to double gloves an impermeable gown is advised.
Sexual prevention Zika virus can be transmitted through sexual intercourse this is of concern due to and association between zika virus infection and adverse pregnancy and fetal outcomes. For regions with active transmission of zika virus all people with zika virus and their partner – pregnant women – should receive information about the risk of sexual transmission of zika virus. Counselling. Safe sex.
Vaccine development Effective vaccine have existed for several viruses of the flaviviridae family, namely yellow fever vaccine, world health organization ( WHO ) experts have suggested that the priority should be to develop inactived vaccines and other non-live vaccines, which are safe to use in pregnant women and those of childbearing age. As of march 2016, 18 companies and institutions internationally were developing vaccine against zika but a vaccine was unlikely to be widely available for about 10 years in Jun 2016 the FDA granted the first approval for a human clinical trial for a zika vaccine.
Diagnoses Diagnosis of zika based on a person’s recent travel history, symptoms, and test result. Blood or urine test can confirm a zika infection. Ultrasound may show findings consist with fetal microcephaly or intracranial calcifications.
Treatment There is no specific medicine for zika virus. We can treat the symptoms. Get plenty of rest. Take medicine such as acetaminophen or paracetamol to reduce fever and pain.
Nursing interventions Assess any recent overseas travel of prenatal patients during or within two weeks of travel. Since there are no antiviral treatments for the virus, supportive care should be given for any symptoms such as rest, antipyretics, pain management and fluids. Patient education.
Teach patient : 1. Pregnant patient or patient who want to get pregnant to avoid visiting countries with high incidence of zika virus. 2. If a patient must travel, teach them how to avoid getting mosquito bites such as using bed nets, window and door screens, staying in air-conditioned rooms and not exposing skin. 3. If the patient thinks that they have the virus and feels sick, they should contact their provider and continue using repellent and protective clothing to avoid transmission of the virus to another person.
Nursing diagnoses Risk for ineffective relationship. Ineffective protection. Fatigue. Activity intolerance. Deficient knowledge. Readiness for enhanced knowledge. Hopelessness. Disturbed body image. Stress overload. Decreases intracranial adaptive capacity. Risk for impaired parenting. Risk for impaired attachment.
Interrupted family processes. Ineffective relationship. Risk for ineffective activity planning. Anxiety. Compromised family coping. Defensive coping. Disabled family coping. Ineffective coping. Grieving. Complicated grieving. Readiness for enhanced power. Powerlessness. Risk for sudden infant death syndrome. Social isolation.
Recommendation WHO is supporting countries to control zika virus disease by taking actions outlined in the “zika strategic response framework” : 1. Define and prioritize research into zika virus disease by convening experts and partners. 2. Enhance surveillance of zika virus and potential complications. 3. Strengthen capacity in risk communication to engage communities to better understand risks associated with zika virus. 4. Strengthen the capacity of laboratories to detect the virus. 5. Support health authorities to implement vector control strategies aimed at reducing aedes mosquito populations.
6 - prepare recommendations for the clinical care and follow-up of people with complications related to zika virus infection, in collaboration with experts and other health agencies.
