A client with Zika virus infection presents with fever, rash, and joint pain. The nurse suspects Zika virus as the cause of these symptoms. What additional symptom might the nurse expect in this client to support the diagnosis?

Choice A rationale:

The nurse should consider recent travel history to a Zika virus transmission area because Zika virus is primarily transmitted through the bite of infected Aedes mosquitoes, and it is more likely for the patient to have contracted the virus if they have recently been in an area where the virus is actively transmitted.

Choice B rationale:

The presence of fever, headache, rash, and joint pain are essential criteria for suspecting Zika virus infection because these are common symptoms associated with the disease. Fever and rash are particularly characteristic symptoms of Zika virus infection.

Choice C rationale:

Laboratory confirmation of Zika virus infection is not essential for suspecting the infection, especially in the early stages when the patient is presenting with symptoms. Zika virus diagnosis often involves clinical evaluation, recent travel history to transmission areas, and symptoms.

Choice D rationale:

Exposure to blood transfusion is not a specific criteria for suspecting Zika virus infection. While Zika virus can be transmitted through blood transfusion, it is not a primary consideration when initially suspecting the infection based on the patient's symptoms and travel history.

Choice E rationale:

The use of aspirin for pain relief is not a criteria for suspecting Zika virus infection. It is not directly related to the disease and would not aid in the initial assessment and suspicion of the infection.

Choice A rationale:

Hepatitis A virus is not closely related to Zika virus. Hepatitis A is a virus that primarily affects the liver and is transmitted through contaminated food or water, not through mosquitoes like Zika virus.

Choice B rationale:

Influenza virus is not closely related to Zika virus. Influenza, commonly known as the flu, is a respiratory illness caused by influenza viruses and is spread through respiratory droplets.

Choice C rationale:

Dengue virus is closely related to Zika virus. Both Zika and Dengue viruses are members of the Flaviviridae family and are transmitted by the same Aedes mosquito species.

Choice D rationale:

Rotavirus is not closely related to Zika virus. Rotavirus is the leading cause of severe diarrhea in young children and is transmitted through the fecal-oral route, not through mosquitoes.
