Heartland virus: un virus co-impliqué dans la maladie de Lyme aux Etats-Unis, et dont les symptômes peuvent être confondus avec ceux de l’ehrlichiose

CDC Reports More Cases of Heartland Virus Disease

New virus infects six more people and found in second state

The Centers for Disease Control and Prevention (CDC) in collaboration with health officials in Missouri and Tennessee have identified six new cases of people sick with Heartland virus: five in Missouri and one in Tennessee. The new cases, discovered in 2012 and 2013, are in addition to two discovered in 2009 and are described today in CDC’s Morbidity and Mortality Weekly Report.

Heartland virus was first reported in two northwestern Missouri farmers who were hospitalized in 2009 with what was thought to be ehrlichiosis, a tick-borne disease. However, the patients failed to improve with treatment and testing failed to confirm ehlrlichiosis. Working with state and local partners, CDC eventually identified the cause of the men’s illness: a previously unknown virus in the phlebovirus family now dubbed Heartland virus.

Ongoing investigations have yielded six more cases of Heartland virus disease, bringing to eight the total number of known cases. All of the case-patients were white men over the age of 50. Their symptoms started in May to September and included fever, fatigue, loss of appetite, headache, nausea, or muscle pain. Four of the six new cases were hospitalized. One patient, who suffered from other health conditions, died. It is not known if Heartland virus was the cause of death or how much it contributed to his death. Five of the six new cases reported tick bites in the days or weeks before they fell ill.
