Infectiologist Xavier Lescure said that Andes hantavirus can progress from mild fatigue to severe pulmonary disease requiring intensive care in a short window.
This alert is critical because the virus often presents with non-specific symptoms that may mislead patients and clinicians before the condition becomes life-threatening.
Lescure said that the virus possesses a long incubation period. However, once symptoms manifest, the decline can be rapid. He described the initial stage as involving "une grande fatigue, une petite dépression, des douleurs, des maux de tête," which translates to great fatigue, slight depression, aches, and headaches.
According to Lescure, the transition from these early signs to severe pulmonary involvement can occur within two to three days [1]. This rapid escalation often leads to a state of "une fièvre intense, quasi constante" — an intense, almost constant fever.
Because the early symptoms mimic common viral infections, the window for medical intervention is narrow. Lescure said that the speed of the progression can move a patient from general malaise to the need for resuscitation and intensive care support in just a few days [1].
The alert emphasizes the danger of the virus's deceptive onset. While the incubation phase may be quiet, the subsequent pulmonary failure happens quickly, leaving little time for treatment once the respiratory system is compromised.
“Andes hantavirus can progress from mild fatigue to severe pulmonary disease requiring intensive care within a few days.”
The rapid clinical deterioration associated with Andes hantavirus complicates early diagnosis. Because the initial symptoms are vague, patients may delay seeking care until the window for effective intervention has closed, increasing the necessity for high-acuity intensive care units to manage the resulting pulmonary failure.
