Zika Virus

11 min read

Zika virus is a mosquito-borne virus that is spread to people primarily through the bite of an infected Aedes species mosquito. The most common symptoms of Zika virus disease are fever, rash, joint pain, and conjunctivitis (red eyes). The illness is usually mild with symptoms lasting from several days to a week. Severe disease requiring hospitalization is uncommon.

Zika virus was first identified in 1947 in Uganda. Outbreaks of Zika virus disease have been recorded in Africa, the Americas, Asia and the Pacific. In May 2015, the Pan American Health Organization (PAHO) issued an alert regarding the first confirmed Zika virus infection in Brazil.

In February 2016, the World Health Organization (WHO) declared Zika virus a public health emergency of international concern (PHEIC). The WHO recommendation to countries and territories was to intensify the detection of infections, to enhance surveillance and to expedite the development of diagnostic tests and vaccines to protect people at risk, especially during pregnancy.

In the United States, local transmission of Zika virus has been reported in Florida and Texas. The Centers for Disease Control and Prevention (CDC) has issued travel notices for people traveling to regions and certain countries where Zika virus transmission is ongoing.

The CDC recommends that pregnant women consider postponing travel to any area where Zika virus transmission is ongoing. All travelers should take steps to prevent mosquito bites.

Causes

Mosquito-Borne Transmission

The Zika virus is primarily spread through the bite of an infected Aedes species mosquito. These mosquitoes are found in tropical and subtropical regions around the world, and they are known to bite during the day and night. The virus can also be spread from mother to child during pregnancy, and through sexual contact.

Environmental Factors

The Zika virus is believed to be more prevalent in areas with warm climates and high humidity. This is because the mosquitoes that carry the virus thrive in these conditions. Additionally, the virus is more likely to spread in areas with poor sanitation and inadequate access to clean water, as these conditions can create breeding grounds for the mosquitoes.

Travel

Travel to areas where the Zika virus is present can increase the risk of infection. This is because travelers may be exposed to infected mosquitoes or come into contact with someone who is carrying the virus. Additionally, travelers may bring the virus back to their home country, where it can spread to other people.

Immune System

The Zika virus is more likely to cause serious health issues in people with weakened immune systems. This includes pregnant women, infants, and people with existing health conditions. Additionally, people who have not been exposed to the virus before may be more likely to experience severe symptoms.

Getting a Diagnosis

Symptoms

The most common symptoms of Zika virus infection are fever, rash, joint pain, and red eyes. Other symptoms may include muscle pain, headache, and fatigue. Symptoms usually last for several days to a week.

Travel History

If a person has recently traveled to an area where Zika virus is known to be present, this can be an indication of a possible infection. Areas where Zika virus is known to be present include parts of Central and South America, the Caribbean, and some Pacific Islands.

Laboratory Tests

Laboratory tests can be used to confirm a diagnosis of Zika virus. These tests include blood tests, urine tests, and tests of other bodily fluids. These tests can detect the presence of Zika virus in the body and can help to confirm a diagnosis.

Treatment

There is no specific treatment for Zika virus infection. Treatment is focused on relieving symptoms and preventing complications. This may include rest, fluids, and over-the-counter medications to reduce fever and pain. It is important to avoid mosquito bites to prevent further spread of the virus.
