The illness is characterised by high fever, sore throat, muscle aches, skin rash (with haemorrhages), headache, abdominal pain, vomiting and diarrhoea. A rat serves as a reservoir for the illness, but person to person transmission is also reported. (27 Sep 1997) |
| leukoencephalitis, acute haemorrhagic | A rare, fatal postinfection or allergic demyelinating disease of the central nervous system having a fulminating course and occurring mainly in young adults. It is characterised by destruction of white matter to the point of liquefaction; widespread necrosis of blood vessel walls leading to the formation of multiple small haemorrhages in the involved areas and the exudation of fibrin into the surrounding tissue; and cellular infiltration of the necrotic areas.
