The World Health Organization (WHO) has moved to counter growing misinformation about hantavirus amid rising public concern and speculation on social media.
The clarification comes as Zimbabwean health authorities announced plans to place three healthcare workers returning from Ascension Island after being identified as contacts of a confirmed hantavirus case.
The Ministry of Health and Child Care said they are asymptomatic and being monitored in line with international protocols.
WHO dismissed claims suggesting ivermectin is an effective treatment for hantavirus, saying there is currently no scientific evidence supporting such assertions.
"Misinformation around hantavirus continues to spread online. Human-to-human transmission of Andes virus is possible but uncommon and typically linked to close, prolonged contact in enclosed settings,” the WHO said.
“Hantaviruses are not new. They are a known group of rodent-borne viruses that have been monitored for decades.
"WHO states there is currently no evidence that ivermectin is effective against hantavirus. Hantavirus is caused by a virus, so antibiotics are not routinely used unless a bacterial infection is also suspected."

WHO further reassured the public that infection is not automatically fatal despite the absence of an approved antiviral treatment.
According to WHO, hantavirus is a rare viral disease mainly spread through contact with infected rodents or exposure to their urine, saliva or droppings.
Symptoms may include fever, headaches, fatigue and muscle pain, while severe cases can develop into serious respiratory complications.
WHO said it continues to work closely with countries and health partners to monitor developments, support patient care and prevent further spread.
