“I want to reassure Iowans that the risk of transmission in our state is incredibly low. We continue to investigate and monitor this situation and implement necessary public health protocols.”

The patient was being cared for by University of Iowa Health Care, which is working closely with Iowa HHS, the CDC and other local public health partners to assist with contact tracing and surveillance, the release said.

What is Lassa fever?

According to Dr. According to Edward Liu, chief of the Division of Infectious Diseases at Hackensack Meridian Jersey Shore University Medical Center, Lassa fever is a hemorrhagic viral infection transmitted by rats in West Africa.

The viral disease is transmitted by a specific species of rat called the “multimammate rat,” or Mastomys natalensis (Mastomys), according to the CDC.

“This is a very rare disease,” Liu told Fox News Digital.

“Public health must monitor the patient’s close contacts to ensure there are no further cases of Lassa fever.”

According to the same source, humans can become infected with the fever through contact with infected rats or their saliva, urine or feces.

“Lassa fever can also spread between people through close contact with bodily fluids,” Lui told Fox News Digital.

“Casual contact is not enough to transmit Lassa fever.”

“Lassa is usually a mild disease, but in severe cases it can cause uncontrolled bleeding and shock.”

The CDC confirmed that Lassa fever is not spread by hugging, shaking hands, or sitting next to someone.

“People with Lassa fever are not contagious until their symptoms appear,” the agency said.

PPE for hospitals

Here are some ways the virus can spread, as listed on the CDC website.

  • Touching contaminated objects
  • Eating foods that contain the virus
  • Infection with the virus through open cuts or wounds
  • eat rodents
  • Inhaling air that contains infected urine or feces, which can occur when cleaning or sweeping
  • Healthcare settings are not using appropriate personal protective equipment (PPE) or not properly sterilizing equipment

Symptoms of infection

While about 80% of people experience only mild symptoms, in rare cases it can be fatal.

“Lassa is usually a mild disease, but in severe cases it can lead to uncontrolled bleeding and shock,” Lui warned.

People with mild illness may experience a low-grade fever, fatigue, weakness and headache, according to the CDC.
