Elevated levels of immunoglobulin M antibodies against various pathogens, most frequently Epstein-Barr-virus and
<jats:named-content content-type="gene">Coxiella burnetii</jats:named-content>
, were detected by immunoassay in 15 of 48 patients (31.3%) with acute Puumala virus infections. Although the mechanisms leading to this IgM response are not clear yet, polyspecific immunoglobulin M antibodies have to be taken into account to avoid misinterpretation of serological results in acute hantavirus infection.
