Tick Surveillance

When ticks are active in Nebraska (April-October), staff from the NE DHHS vector-borne disease program and local health departments including ELVPHD search for ticks at various sites throughout the state in a process called "tick dragging." Using a white canvas cloth, ticks are collected, sent to the lab, identified to species under a microscope, and tested for pathogens. Tick surveillance provides actionable, evidence-based information to clinicians, public health practitioners, policymakers, and the public on where and when people are at risk for exposure to ticks and tick-borne disease pathogens.

Rabies

Rabies is a viral disease of the nervous system which can infect humans through the saliva of infected animals. Animals that may carry the rabies virus are dogs, cats, bats, raccoons, coyotes, foxes, and skunks. Rabies is passed to humans from rabid animals through bites or saliva entering an open wound. Even after exposure, rabies is preventable if given proper medical treatment. Elkhorn Logan Valley Public Health Department helps people with understanding animal testing steps and to decide if exposure to rabies was likely so proper medical treatment can be sought.

What is Radon

Radon is an invisible, odorless gas that occurs naturally in the soil and can enter homes through cracks and holes in the foundation, walls and water pipes.

In Nebraska there are dangerously high levels of Radon and nearly one in two homes has levels well above the safe zone. 

To help protect you and your family, Elkhorn Logan Valley Public Health Department carries Radon test kits for sale year-round at any of our three offices (Norfolk, Tekamah, Wisner) OR they can be purchased online and we will ship them to your home. We also provide information on how to fix existing homes to lower Radon levels and Radon resistant methods for new home construction. 

Why Radon Testing Matters

• Radon is a colorless, odorless, radioactive gas.
• Leading cause of Lung Cancer among Non-Smokers.
• Testing is the ONLY Way to know a home's radon level.

EPA Radon Action Level

Knowing the Radon level in your home is important because the problem can be fixed by installing a Radon mitigation system.

• Long‑term exposure increases the risk of lung cancer, especially for children and non‑smokers.
• There is no safe level of radon exposure.
• The U.S. Environmental Protection Agency (EPA) recommends fixing homes with radon levels at or above 4.0 pCi/L.
• It is important for people building new homes to learn about Radon resistant construction techniques.

West Nile

West Nile Activities at Elkhorn Logan Valley Public Health Department:

Insects can not only be annoying during humid, summer months, but they can also carry harmful diseases. Some mosquitoes carry West Nile virus which can be spread to humans and cause illness. Since 2006, Elkhorn Logan Valley Public Health Department (ELVPHD) has conducted West Nile tracking activities and has provided prevention education each summer. West Nile Virus activity is tracked by using mosquito traps in select areas and by collecting dead birds for lab testing.

West Nile virus Health Information:

West Nile virus is an arthropod-borne virus (arbovirus) most often spread by infected mosquitoes. West Nile virus can cause serious illness. It was first found in North America in 1999, and has since spread across the continental U.S..

Risk Factors

Most people get infected with West Nile virus by the bite of an infected mosquito. Mosquitoes become infected when they feed on infected birds. Infected mosquitoes can then spread the virus to humans and other animals. The risk of infection is highest for people who work outside or those who take part in in outdoor activities because of greater exposure to mosquitoes. In a very small number of cases, West Nile virus has been spread through blood transfusions, organ transplants, and from mother to baby during pregnancy, birth, or breastfeeding. People with certain health problems, such as cancer, diabetes, high blood pressure and kidney disease are also at greater risk for serious illness.

Signs and Symptoms

If bitten by an infected mosquito, people normally develop symptoms of West Nile virus between two days and two weeks later. The Centers for Disease Control and Prevention (CDC) states that about 80% of human infections of West Nile virus cause no symptoms, while 20% cause flu-like symptoms, including fever, weakness, headache, and muscle or joint pain. A small number of people (less than 1%) will have severe neurological illness including headache, high fever, neck stiffness, disorientation, coma, tremors, seizures or paralysis which may last for many weeks or months and cause permanent neurological damage. About 10% of those who develop neurological symptoms will die.

Prevention

The best way to avoid West Nile virus disease is to prevent mosquito bites:

• Use insect repellents (bug spray) when you go outdoors. Those which DEET, picaridin, IR3535, and some oil of lemon eucalyptus and para-menthane-diol products provide longer-lasting protection.
• Wear long sleeves and pants from dusk through dawn when many mosquitoes are most active.
• Install or fix screens on windows and doors. If you have it, use your air conditioning.
• Help lower the number of mosquitoes around your home. Empty standing water from containers such as flowerpots, gutters, buckets, pool covers, pet water dishes, discarded tires, and birdbaths.
