Visceral Leishmaniasis in Spain

Thursday, March 29th, 2012

The following background data are abstracted from Gideon www.GideonOnline.com and the Gideon e-book series. Primary references avaialable on request.

Time and Place:
Visceral leishmaniasis is most common in the southern region, notably Andalusia, Palma de Mallorca, Valencia and Catalonia.

Tick-borne Encephalitis in Hungary

Friday, March 23rd, 2012

Tick-borne encephalitis was first reported in Hungary in 1977. [1,2] The disease is most common in forested, hilly areas of the western and northern regions. Highest incidence is reported from western Hungary, west of the Danube; the region surrounding the Balaton extending to the Austrian and Croatian borders; the areas to the west and north of Budapest, along the border to the Slovak Republic.

High rates are reported in the areas surrounding Zala, Somogy, Vas (western Hungary) and Nograd (northern Hungary). Sporadic cases occur on the river Theil, the areas east of Miskolc. Disease rates correlate with proximity to a forested habitat within a 2500-meter radius of a town or village.

The incidence of TBE in Hungary has decreased somewhat since the 1990′s and continues to be similar to those of bordering countries – see graph. [3]

The second graph compares the incidence of TBE with those of other arthropod-borne diseases in Hungary.

Seroprevalence surveys:
26.5% of cattle, 7.0% of sheep, and 0.0% of horses in northeastern Hungary (2008 publication)

Notable outbreaks:
2007 – An outbreak (25 cases) was associated with consumption of raw goat milk.

American Hemorrhagic Fevers

Tuesday, March 13th, 2012

[comment on Venezuelan hemorrhagic fever - Venezuela: (PO)]

A recent posting in ProMED described three arenaviruses found in South America: Guanarito virus, Machupo virus and Junin virus. Three additional human pathogens have been reported in the Americas: Sabia virus (Brazilian hemorrhagic fever) first reported in Sao Paulo in 1990; Whitewater Arroyo virus implicated in cases of fatal hemorrhagic fever in California during 1999 to 2000; and Ocozocoautla de Espinosa virus, recently described as a possible cause of hemorrhagic fever in southern Mexico.

Malaria Trends in Central America

Sunday, March 11th, 2012

Although disease rates in Honduras have tended to be slightly higher than those of neighboring countries for much of the past five decades, the incidence of malaria in the region has been decreasing since 2000. [1-3] See graph:

Animal Rabies in Romania

Thursday, March 8th, 2012

Recent sporadic cases of rabies associated with a dog and a cat belie the fact that most animal rabies in Romania involves foxes. [1,2] See graph:

In fact, the incidence of fox rabies in Romania excedes that reported by adjacent countries. [3] See graph:

Hepatitis A in English-speaking Countries

Saturday, March 3rd, 2012

A recent outbreak in Aukland belies the fact that rates of hepatitis A in New Zealand are low. In fact, since 2000 incidence figures for all forms of viral hepatitis in this country have even been exceeded by those of leptospirosis and rheumatic fever [1] – see graph [2]:

During the same period, rates of hepatitis A among the six major English-speaking countries have been decreasing, and continue to be surprisingly similar – see graph:

Only one country in this group, the United States, employs routine vaccination against Hepatitis A. Two other countries, Canada and Australia, administer the vaccine to high-risk populations only. [2]
