Incubation Period of Hantavirus Cardiopulmonary Syndrome

Prospective Evaluation of Household Contacts of Persons with Hantavirus Cardiopulmonary Syndrome in Chile

“…Although acquisition was probably from exposure to rodents in 3 of the 16 cases and was unclear in 1, we believe that the remaining 12 cases resulted from person-to-person contact. The time intervals between the onset of symptoms were consistent with the incubation period for ANDV infection [8,17], multiple variables associated with close contact with the index case patient were associated with increased risk of acquisition, and 3 of the 12 lived in urban areas where the only possible exposure to ANDV was from contact with the index case patient.…”

“…The intervals of 4 and 6 days between the onset of symptoms were shorter than the known incubation period for ANDV infection [17]. Additional case patients 1 and 2 were not sex partners with their index case patients and shared common exposure to environmental sources, including the demolition of a shed for additional case patient 2.…”

Diagnosis and treatment of new world hantavirus infections

“…In most cases the individual has had prolonged exposure to environmental sources and the exact incubation period is unknown. There have, however, been published reports from approximately 20 well-described cases in north and south America in which the period of exposure was limited to 2 days or less [14,20,21]. These included person-to-person transmission of ANDV after a day-long automobile trip [17], infection after rodent bites [14], and infection after brief trips to high-risk areas followed by the return to an urban area without risk of infection [21].…”

“…The incubation period may be as short as a few days and may be up to 6 weeks or more [14,20,21]. In most cases the individual has had prolonged exposure to environmental sources and the exact incubation period is unknown.…”

“…, Olsson et al7 , Vial et al8 , Young et al9 , and references therein). The typical clinical picture starts with acute onset of fever followed by symptoms as headache, abdominal pain, nausea, vomiting, diarrhoea and signs of renal impairment 2.…”
