Tularemia in Liechtenstein

A recent post in ProMED reported that a hare infected with tularemia had been identified in Liechtenstein.  http://www.promedmail.org/post/6143364  Although Liechtenstein  reported no cases of human tularemia during January 1, 2003 to November 6, 2018, the neighboring territory of Switzerland has experienced a remarkable increase in disease incidence.  In fact, current rates of human infection in Switzerland are reminiscent of those reported in the United States during the 1930’s. [1-3]

Rabies in Costa Rica

Recently, a biologist in Costa Rica acquired rabies while working in a cave.  For over five decades, Costa Rica has reported the lowest rates of rabies in Central America (El Salvador reports the highest rates), both in terms of cases and cases per 100,000 population. [1,2]   Costa Rica also reports the lowest incidence of animal rabies for the region.

In the above graph, data for Costa Rica appear as a row of red dots at the lower margin (arrow).

Legionellosis in New Zealand

Rates of Legionellosis have increased sharply since 2005 and are currently more than twice those reported in Australia and the United States. [1-2]  See graph below [3]

Leptospirosis in Israel

The following background information on Leptospirosis in Israel is abstracted from Gideon www.GideonOnline.com and the Gideon e-book series. [1,2] Primary references are available from the author.

Leptospirosis is most common in agricultural settlements of the Galilee, during the months of June to September.  Reported disease incidence reached a peak of 81 cases in 1962, but have since decreased considerably. 48 cases were reported during 2002 to 2008 – including 20 travel-related cases (15 of these acquired in southeast Asia).  Rates per 100,000 have been comparable to those reported in the United States for the past three decades (see graph) [3]

During 1970 to 1973, the main infecting serovars of Leptospira interrogans were grippotyphosa (41%) and hebdomadis (31%).  Serovars hardjohebdomadis and grippotyphosa accounted for 79% of cases during the 1970’s, and 32% during 1985 to 1999.  Serovar. icterohaemorrhagiae accounted for 2% during the 1970’s, and 29% during 1985 to 1999.

14 fatal cases of leptospirosis were reported during 1954 to 2017, the most recent in 1999.

The following chart summarizes five outbreaks of leptospirosis reported from Israel.

Legionellosis in Italy

The following background data are abstracted from Gideon and the Gideon e-book series. [1,2]  (Primary references are available on request).

The first case of legionellosis in Italy was reported in 1981 (from Emilia Romagna), and passive surveillance was initiated in 1983.  Reported disease rates in Italy and surrounding countries have increased dramatically since 2000.  The rate of under-reporting for legionellosis in Italy is estimated at 21.4%

As seen in the following graph, parallel rate increases have been reported in the United States and Italy.  Disease rates in the latter are approximated five-fold those reported for the European Region as a whole, and 1.3-time higher than those reported in the United States.

Approximately 63% of cases are reported from Northern Italy (1983 to 1994); and Legionella pneumophila serogroup 1 is responsible for 94% of cases.  The male/female ratio for reported cases is 3.45/1;  and 56.6% of the patients are above age 49.

819 presumptive cases and 490 confirmed cases were registered during 1983 to March 1994, including 67 fatal cases during 1983 to 1990.  9,803 cases (11.8% fatal) were reported during 2000 to 2011.

During 1973 to 1987, 117 cases (6 fatal) were reported among tourists to Italian summer resorts.  During 2002 to 2007, the annual incidence of legionellosis among European travelers to Italy ranged from 96 to 143 cases.  Seven cases were reported among tourists in Rome during 1998 to 1999, and 10 cases in 2000.  In 2003, 64 internal (Italian) tourists acquired legionellosis within Italy.

The following screen-shots from Gideon www.GideonOnline.com summarize published outbreaks and surveys for legionellosis in Italy.

Leishmaniasis in Palestine

In the following charts, I’ve compared reported incidence rates for cutaneous leishmaniasis in the two states which comprise Palestine.  Note that disease rates in  a third area (Gaza / West Bank) are two- to three-fold those reported by Israel and Jordan.  Significantly, current rates in Syria (per 100,000) are approximately one hundred-fold those of Israel (280 vs. 3 in 2016) [1,2]

Campylobacteriosis in New Zealand

The following background information on campylobacteriosis in New Zealand is abstracted from Gideon www.GideonOnline.com and the Gideon e-book series. [1-2]  (primary references available on request)

The incidence of campylobacteriosis exceeds that of any other reportable disease in New Zealand.  In fact, Campylobacteriosis accounted for 42.5% of all notified cases of infectious disease in 2010.  Highest rates are reported during late spring and early summer (November to January).  Rates on South Island are correlated with lower socio-economic level, proportion of persons ages 25 to 44 and density of fresh food outlets. The Far North and much of the rural North Island report relatively low disease incidence during summer, with minimal inter-seasonal variation. Highest summer incidence and inter-seasonal variation are reported in Christchurch, Dunedin, much of the South Island, Wellington and Upper Hutt.  47% of campylobacteriosis cases are acquired from food, 28% direct animal contact, 7% overseas travel, 4% person-to-person transmission and 3% water-related.

The following graph compares the yearly reported incidence of six diseases associated with diarrhea.  Note that giardiasis is more common than salmonellosis, shigellosis and VTEC (verotoxin-producing Escherichia coli) infections in this country.  Significantly, 2,056 patients were hospitalized for Guillain-Barre syndrome (a condition which often complicated campylobacteriosis) during 1988 to 2010.  Decreasing rates of campylobacteriosis since 2007 were ascribed to efficient disease control among poultry.

In the second graph, I’ve contrasted rates of campylobacteriosis in New Zealand with those of other English-speaking countries.

Zoonotic Disease Deaths in the United States

With the exception of salmonellosis, deaths from Rocky Mountain spotted fever (RMSF) * have exceeded those of other reportable zoonoses in the United States for most of the past six decades. [1,2]    Rabies was the predominant cause of zoonotic death prior to 1950; Lyme disease and West Nile fever since 2000.

* Since 2010, reporting of “Rocky Mountain spotted fever” has been broadened to include related diseases –  under the heading “Spotted fever rickettsiosis”

Escherichia Coli Enteritis in Ireland

Rates of disease due to Verotoxin-producing Escherichia coli (VTEC) in Ireland have increased dramatically since 2010, and are currently eight-fold those reported in the United States.  Significantly, corresponding rates of hemolytic-uremic syndrome and E. coli O157 infection in Ireland have changed little during this period. [1-3]

Japanese Encephalitis in Assam State

Since 2008, data regarding Japanese Encephalitis in India have distinguished between Japanese encephalitis [JE] and Acute encephalitis syndrome [AES].  Cases of the latter have been variously ascribed to Chandipura, enteroviral infection, scrub typhus and lychee fruit intoxication.  [1,2]    In 1963, 22% of individuals in Assam (Lakhimpur and Darrang districts) were seropositive toward JE virus.  Surveys conducted during 2006 to 2014 found that Japanese encephalitis was responsible for 30% to 78% of acute encephalitis cases in Assam.  A study published in 2007 found that 19.3% of patients with Japanese encephalitis in Assam State have concurrent neurocysticercosis.  In the following chart, I’ve compared reported incidence for these two conditions in India and in Assam State. [3]
