Differentiating Zika virus infection from other Diseases

Natural History, Complications, and Prognosis

Symptoms

Symptoms associated with the contraction of the Zika virus typically span from several days to a week. The disease is rarely fatal and hospitalization is uncommon. The following symptoms are the associated with contracting the Zika Virus: ^[1]

Acute onset fever
Maculopapular rash
Arthralgia
Conjunctivitis
Myalgia
Headache
Retro-orbital pain
Vomiting

Diagnosis

The Zika virus is commonly misdiagnosed as many other diseases. These diseases include dengue, leptospirosis, malaria, rickettsia, group Astreptococcus, rubella, measles, parvovirus, enterovirus, adenovirus, and alphavirus infection.
Diagnosis is initially based on patients recent history, including places traveled.
Blood serum and plasma testing is conducted to detect viral nucleic acids or virus specific IgM. Laboratory testing is the primary source when differentiating between Zika and other commonly misdiagnosed viruses.^[2]

Medical Therapy

There is currently no specific antiviral treatment for the Zika virus.
Modern therapy tactics include increased rest, fluids, antipyretics (fever reducers) and analgesics (pain relievers).
Non-steroidal anti-inflammatory drugs (NSAIDs) should be avoided until dengue fever is no longer a potential diagnosis.^[2]

Primary Prevention

Avoid mosquito bites:

Use insect repellent.
Wear long sleeves and long pants.
If outdoors or cannot protect against mosquitos entering the home, use bed nets, air conditioning, or insect screens
Avoid standing water: gardening pots, swampy areas, etc.^[2]
