zika virus symptomsZika Virus | International Public Health Emergency

 

Zika Virus is a global health scare, especially for pregnant women.  Due to the October 2015 cluster of 524 cases of newborns in Brazil diagnosed with microcephaly and other neurological disorders reported in Brazil, World Health Organization (WHO) has stated that it is as a Public Health Emergency of International Concern. (bit.ly/1PYrRKs)

What are the symptoms of the Zika Virus?

zika virus microcephalyWhen humans become infected, they may develop symptoms which include fever, itchy rash, headache, red eyes, joint pain, muscle pain, and temporary paralysis.  Typically, symptoms last for 2 to 7 days.  Incubation period is unknown, but ranges from a few days to a week (1.usa.gov/1MMg1Qi).

There has also been an increase in incidence of Guillain-Barré syndrome that has coincided with increased incidence of Zika Virus. (bit.ly/22Tg8mx)

Pregnant women infected with the virus have had newborns with microcephaly and brain damage.  It is believed that the virus has spread from the infected mother to baby in utero and during delivery.  Zika virus has been found in the brain tissue of these infected babies.

Where Did Zika Virus Start?


zika_americas_03-18-2016_webAccording to WHO, it was originally detected in a rhesus monkey in Zika Forest, Uganda in 1947 and in humans in Nigeria in 1954 (bit.ly/1QeAEcO).  Before 2015, the virus was found in Africa, Southeast Asia, and the Pacific Islands.  Currently, there are many countries around the world with local mosquito-borne Zika virus disease cases as noted on the CDC website at 1.usa.gov/1Mv4zhb  Currently, countries affected by local transmission include Aruba, Barbados, Bolivia, Bonaire, Brazil, Colombia, Puerto Rico, Costa Rica, Cuba, Curacao, Dominica, Dominican Republic, Ecuador, El Salvador, French Guiana, Guadeloupe, Guatemala, Guyana, Haiti, Honduras, Jamaica, Martinique, Mexico, Nicaragua, Panama, Paraguay, Saint Martin, Saint Vincent and the Grenadines, Sint Maarten, Suriname, Trinidad & Tobago, U.S. Virgin Islands, and Venezuela).

 Is Zika Virus in the United States?

zika-by-state-report_03-23-2016_webYes.  However, only travel associated cases have been reported in the United States.  However, "local mosquito-borne transmission of Zika virus has been reported in the Commonwealth of Puerto Rico, the US Virgin Islands, and America Samoa." (1.usa.gov/1RvWNAq)  As of March 28, there have been 273 travel associated cases have been found in the U.S., including in Hawaii.  There have been 258 locally acquired cases in Puerto Rico, 10 in the U.S. Virgin Islands & 14 cases in the American Samoas.  

 

How is Zika Virus Transmitted?

It is most commonly transmitted by a mosquito bite.  It can also be sexually transmitted and via blood transfusion. It is unknown how common sexual or blood transmission is among humans.

Can Zika Virus Be Sexually Transmitted?

Yes.  The CDC recently reported on February 2, that this virus was sexually transmitted in Texas, USA (cnn.it/1WSuiRd).  In addition, Florida confirmed on March 9 & California confirmed on March 25, that they too have had their first case of sexually transmitted Zika Virus. As a result of confirmed sexual transmission of the virus, the CDC now recommends that if you are a pregnant women whose "male sexual partner has traveled to or lives in an area with active Zika virus transmission, you should abstain from sex or use condoms the right way every time you have vaginal, anal, and oral sex for the duration of the pregnancy."  The case in Texas did not involve pregnancy.  However, keep in mind that this illness can infect anyone.

Other countries, confirmed that they too have had their first case of sexually transmitted Zika Virus.  France confirmed this occurred on February 27.  Chile confirmed firmed this on March 27.  Be aware that more cases and countries are confirming sexual transmission of the virus.

What Can I Do to Prevent Zika Virus?

Use insect repellent, especially when outdoors.  Avoid travel to areas with active Zika Virus transmission.  If you cannot avoid travel to an area with active transmission, then practice abstinence or use birth control while traveling in that area.  Abstain from sex if your partner has traveled to an area with active transmission.  

What Insect Repellent is Best to Zika Virus Infection?

The CDC recommends the use of insect repellents with active ingredients registered with the U.S. Environmental Protection Agency (EPA) for use to be applied to skin and clothing.  EPA registered insect repellents contain DEET, picaridin, IR3535, and some oil of lemon eucalyptus and para-menthane-diol.  Insect repellents with these active ingredients products offer longer-lasting protection.  Insect repellents containing oil of lemon eucalyptus should not to be used on children under the age of three years.  Insect repellents can be used by pregnant and nursing women.  The CDC has many details about use, efficacy, and safety of insect repellents available at 1.usa.gov/25rRxr1.

I'm Worried Myself or My Child Might Have Zika Virus.  What Should I Do?

First, know the symptoms.  Typically, at a minimum, an infected person may have a low grade fever which is frequently accompanied by and a rash.  Next, contact your doctor.  If your doctor is concerned that you or your child might be infected with Zika Virus, they will advise you to schedule an appointment for a more detailed evaluation.  Lastly, if your doctor thinks that you may need to be tested for Zika Virus, then your doctor will refer you to your local health department.  Currently, only local health departments have testing for the Zika Virus. 

Is There a Travel Advisory Due to Zika Virus? 

Yes. There is a Alert Level 2, Practice Enhanced Precautions in areas with active transmission (1.usa.gov/1MMaER1).  There is not yet a Warning Level 3, Avoid Nonessential Travel for areas with active transmission.

I'm Not Pregnant & Plan to Travel to an Area with Zika Virus.  Is There Anything I Should Do?

What is Ebola? 

Ebola is a virus that was first discovered in 1976 near the Ebola River in Africa. Sporadic outbreaks have occurred in Africa since then. There are five (5) strains of Ebola that infect animals in Africa. Four of the strains infect humans.

 

What are the Signs & Symptoms of Ebola?

Symptoms include fever, headache, muscle aches, vomiting, diarrhea, abdominal pain, unexplained bleeding or bruising.  Ebola can only be spread when symptoms begin. Symptoms typically occur between 8 to 10 days after infection.  However, symptoms may occur as late as 21 days after exposure to Ebola. 

 

How is Ebola Spread?

If a person is ill with Ebola virus, they can spread it by blood, body fluids (urine, saliva, sweat, feces, vomit, breast milk, and semen).  It can also be transmitted via objects contaminated with the virus (like needles and syringes). Lastly, it can spread via infected bats, apes, gorillas, and monkeys. (http://1.usa.gov/1rCptdl)

 

Where is the Ebola Outbreak? Where Has Ebola Spread?

This year is the largest Ebola outbreak in history.  It has taken place largely in West Africa.  Currently, areas designated by the U.S. Centers for Disease Control and Prevention (CDC) as having widespread transmission of Ebola are in West Africa, specifically Guinea, Liberia, and Sierra Leone.  Countries that have had travel associated transmission and local transmission are (Port Harcourt and Lagos) Nigeria, (Madrid) Spain, and (Dallas and New York City), New York.  Countries that have had travel associated transmission are (Kayes) Mali and (Dakar) Senegal.

 

Are there are recent updates in Florida?

As of October 26, 2014, Florida Governor Scott issued an order mandating the Department of Health to have a 21 day monitoring of anyone who has returned from areas where individuals have been infected by Ebola virus, as designated by the CDC. (http://bit.ly/1wH4o6M) New York, New Jersey, Illinois and now Florida have instituted a 21 day health evaluation plan. Twice daily monitoring is to include measuring temperature twice daily.  Gov. Scott also stated that if individuals monitored are assessed to be high-risk, then a mandatory quarantine will be required.

 

Are There U.S. Guidelines for Healthcare Workers Caring for Patients with Ebola?

The CDC has issued guidelines for healthcare workers and healthcare settings for those caring for patients infected with, suspected to be infected with, or having died of Ebola. (http://1.usa.gov/1yJblVf) There are also CDC Ebola waste management guidelines. On October 14, 2014, the CDC admitted that they were unprepared for Ebola in the U.S. (http://bit.ly/1E4V6F4)  Since then, the CDC has formed the previously mentioned guidelines.  

 

Are there flight Restrictions from Africa?

As of October 21, 2014, the U.S. Homeland security Department announced that travelers from Guinea, Liberia, and Sierra Leone have limited airport entry into the U.S.  They are limited to five (5)  international airports in New York, New Jersey, Atlanta, Chicago, and Washington, DC.  These airports will have extra screening of passengers for possible Ebola exposure, which include taking temperatures and other assessments as well.  All U.S. airports are screen for possible Ebola exposure. (http://www.cdc.gov/vhf/ebola/pdf/ebola-algorithm.pdf)  Currently, there is no travel ban from or to Guinea, Liberia, and Sierra Leone to U.S. due to Ebola.

 

It is highly unlikely that Ebola will spread in the U.S. as it has in endemic West Africa. However, we must keep a vigilant eye on developments, travel screenings are necessary, and healthcare workers must follow CDC guidelines to prevent spread of this disease.
