Zika was a hot topic, but now it seems like it is a thing of the past. People always ask me…”Is Zika still is a thing?” And my response is, “Of course! Just because it has declined, certainly does not mean that it isn’t still a public health threat.”
Interesting enough, comments like “Is Zika still a thing” come from physicians and various public health professionals as well as individuals living in regions with active Zika transmission. Those that express more of a concern include individuals that have planned future travel to the state of Florida and are planning to conceive, or a close family member of someone who is currently pregnant.
What is Zika?
Perhaps you never heard of Zika, or still quite aren’t sure what Zika is exactly. Zika can be described as a virus that spreads to people primarily through the bite of an infected Aedes species mosquito. It is closely related to other flaviviruses such as Zika can also be transmitted sexually from a person that has Zika to their partner as well as from a pregnant woman to her developing fetus, which can result in serious birth defects.

My role, criteria for testing, testing/funding limitations
I was hired as one of two Zika Case Managers within my local county health department through funding allocated to the state of Florida by the CDC. One of my duties is to coordinate the testing of suspected local, or travel cases, pregnant women, and any infant born to a potentially exposed pregnant woman. The testing criteria for pregnant women include those who traveled to a Zika-active transmission area, had sexual exposure during pregnancy, or 8 weeks prior regardless of the mother’s testing status, as well as those with any abnormal ultrasound results. Testing is also recommended if the mother was not previously tested. Just like other reportable infectious diseases, it takes effective communication between health professionals at all levels to get quality information across regarding Zika. In order to get the job done, we collaborate with infection control practitioners of local hospitals, nurses, physicians, and other public health clinicians to get samples of babies collected at birth for Zika testing while also making sure that a head ultrasound and hearing test are performed on the baby. This is very important because once the baby leaves the hospital it is almost impossible to get samples collected. A majority of the pediatric clinics don’t have the means to ship the specimens to the state laboratories. Some of the general responses we have received from these clinics include not knowing how to properly prepare the specimens for shipping, having the money to do so, and lack of knowledge about billing the patient’s insurance for the procedure. Although the county health department has the access and ability to ship specimens, it would be a liability for us to ship the specimens if another facility collected the samples.
As of March 2017, the department of health has conducted Zika virus testing for more than 13,020 people statewide. At Governor Scott’s direction, all county health departments were mandated to offer a free Zika risk assessment and testing to pregnant women. Unfortunately, due to a decline in cases, and federal funding allocated to state programs winding down, free testing is no longer accessible to the community, and is only provided on a case by case basis. Zika tests can be pretty expensive ranging anywhere from $200 – $400 when conducted at a commercial laboratory and even more in some cases.
State laboratories have just about depleted federal funds received for testing initiatives. If a patient does not meet testing criteria at our department of health, we recommend testing through affiliated commercial laboratories. In addition to the many changes in testing criteria including requiring patients to show proof of insurance, there has been issues with the insurance companies and patients’ have been incorrectly billed over $1000 for their Zika tests when in fact the test was free. This has been a big issue with tests conducted as far back as November and December which we have recently been made aware of. Mosquito control services specifically for Zika efforts provided by our county health department’s Environmental Health program has ended.
Management of Infants with confirmed, or possible Zika Infection
Currently, we have reached the stage where the pregnant women that are case managed have already given birth. We are now tasked with conducting 24 month active follow-ups of all infants exposed to a positive mother via in utero. We conduct follow-up of the infants exposed regardless of whether the infant tested negative, or positive. These infant follow-ups occur at 2, 6, 12, 18, and 24 months. This is because abnormalities can still occur during child development. A majority of our babies being followed are currently between the 12 and 18 month mark.
Out of all the babies we have tested, and are currently following, only one is confirmed to be microcephalic. Looking into the future, at the 18 month follow-up mark, the infants being followed will have to be re-tested in order to confirm if the antibodies are indeed negative or positive. Another complication with testing these babies will be whether the baby has traveled since it has been born. There is a possibility that the baby could have been infected during travel and not in utero. As of July 31st 2018, Zika contracts for our county health department will end and it is unsure who will take on the responsibility for maintaining the case management of these families.
Best practices we have utilized as a county has been community outreach which we collaborate across the division of communicable diseases. I have been able to work closely with a CDC field assigned Zika Community outreach nurse to assemble and distribute Zika prevention and testing kits with a specific focus on obstetrician-gynecologist and pediatricians. We have been able to identify the gaps in testing and communication among our health department and local hospitals, clinics, and private physician offices. Additional community outreach activities of focus include visiting women, infant, and children (WIC) clinics throughout the county in order to conduct health education on Zika as well as community health fairs primarily within the Haitian population due to Haiti being one of the top countries which we get the most amount of travel related cases. Unfortunately, these outreach efforts will also end at the end of this summer due to the depletion of funds, and our CDC field assigned nurse’s contract ending.
Where we are now
As of right now, Florida still does not have any identified areas with ongoing, active Zika transmission. Florida is a hotspot for vacationers, especially the counties of Miami-Dade and Broward. Since the local transmission of Zika in 2016 in both counties, it seems that very few individuals consider Zika as being a major concern. Very few physicians’ are screening for Zika. Some still aren’t sure what it is exactly, and how it can affect an unborn fetus. Congenital Zika infection is still a global health threat to pregnant women and their infants. Zika is still a fairly new infectious disease, and we are learning as we go, especially the risks after pregnancy. The reality is that Zika is here to stay. Funding for zika prevention and treatment should be a top priority in order to aid in the health and wellbeing of children and families across the United States.
