Zika Virus

Please click the frequently asked questions below for further information and IPC precautions required:

• What is Zika Virus?

  Zika virus is a mosquito-borne virus first identified in Uganda in 1947 in a Rhesus macaque monkey followed by evidence of infection and disease in humans in other African countries in the 1950s.

  

• How does it spread?

  Zika virus is primarily transmitted by infected mosquitoes of the Aedes (Stegomyia) genus, mainly Aedes aegypti, in tropical and subtropical regions. Aedes mosquitoes usually bite during the day. These mosquitoes also transmit dengue, chikungunya and urban yellow fever.

  Zika virus is also transmitted from mother to foetus during pregnancy, as well as through sexual contact, transfusion of blood and blood products, and possibly through organ transplantation.

• What are the symptoms?

  Most people infected with Zika virus do not develop symptoms. Among those who do, they typically start 3–14 days after infection, are generally mild including rash, fever, conjunctivitis, muscle and joint pain, malaise and headache, and usually last for 2–7 days. These symptoms are common to other arboviral and non-arboviral diseases; thus, the diagnosis of Zika virus infection requires laboratory confirmation.

  Zika virus infection during pregnancy is a cause of microcephaly and other congenital malformations in the infant, including limb contractures, high muscle tone, eye abnormalities and hearing loss. These clinical features are collectively referred to as congenital Zika syndrome.

  Zika virus infection can also cause Guillain-Barré syndrome, neuropathy and myelitis, particularly in adults and older children.

• Why is this important?

  If NIAS staff are aware that the patient has a suspected or confirmed case this should be communicated to the Control Room (Emergency or Non-emergency as appropriate) and the staff in the receiving unit when transferring the patient to ensure effective patient care and management.

• IPC Precautions
  • Standard Precautions should be used.
  • Hand Hygiene should be completed as per the 5 moments in line with usual practice.
  • Eye protection should be risk assessed for any concern regarding a splash risk.
  • Gloves and Aprons should be risk assessed and worn if contact with the patient’s blood or bodily fluids.
  • Laundry should be treated as per usual local policy.
• What cleaning is required?

  All equipment and the ambulance should have an in-between patient clean, paying particular attention to touch points.

• Do staff need prophylaxis or follow up?

  No staff follow up required.
