Experimental infection of Phlebotomus papatasi with sand fly fever Sicilian virus.

Experimental studies were conducted to evaluate humans as hosts infecting the sand fly Phlebotomus papatasi with sand fly fever Sicilian (SFS) virus. Viral antigen and infectious virus circulated in the blood of infected volunteers on days 4 and 5 after intravenous inoculation with SFS virus. Viremia levels during the latter period were high enough to infect feeding sand flies, but only 13% (9/69) of the flies became infected. One out of every 3 infected sand flies that survived to feed a second time transmitted SFS to a hamster. These results confirm a vertebrate-sand fly-vertebrate transmission cycle for SFS virus, and demonstrate that horizontal transmission may contribute to the maintenance of this virus in nature.

[Meningitis caused by Toscana virus during a summer stay in Italy].

A 44-year-old woman suffered fever, headache and meningism during a summer stay in a region of central Italy where sand-fly fever is endemic. A few days after returning to the Netherlands, she appeared mentally and physically slow but had no fever. Because of the possibility of viral meningitis an examination of the cerebrospinal fluid (CSF) was carried out. This revealed a cell count of 1074/3 cells. Toscana virus antibodies of the IgG and IgM subclass were detected in two respective serum samples and in the CSF. This led to the diagnosis 'Toscana virus meningo-encephalitis'. Toscana virus is classified amongst the sandfly fever virus group. These viruses are transmitted by sand flies (Phlebotomus species) which reside in humid areas around the Mediterranean. Toscana virus is the main cause of viral meningoencephalitis in some areas of central Italy and possibly in southern Spain. The patient recovered within a few days without antiviral therapy. Toscana virus meningo-encephalitis should be included in the differential diagnosis of holidaymakers with neurological symptoms returning from the Mediterranean.

Serological studies on sandfly fevers in the Republic of Bangladesh.

Blood samples from 160 inhabitants of the Republic of Bangladesh were studied by haemagglutination inhibition (HI), indirect HI, and radial haemolysis in gel tests. The sera were found to contain antibodies to the arborviruses of Sicilian (6.25%) and Naples (1.25%) sandfly fevers and to the Karimabad virus (11.25%) which are transmitted by Phlebotomus papatasi. Antibodies to the Karimabad virus were found among the Bangladesh population for the first time.
