African Trypanosomiasis: Crossing Borders

141 individual importations (193 patients) of African trypanosomiasis are listed by Gideon www.GideonOnline.com  Ten of these patients acquired the disease in Zambia, and 27 were treated in South Africa.

As of February, 2019 the Gideon web application and e-book series [1,2] list 2,718 individual cross-border events, arranged in 134 charts – by disease and country.  Charts also include importation of infected animals (ie, rabid dogs) and contaminated foods and other vehicles which resulted in outbreaks.  Charts in the web application are interactive, and allow the user to sort data according to country, year, number of cases, etc.  In the following screen shots, I have sorted the African trypanosomiasis chart to display cases originating in Zambia (upper box) and cases imported into South Africa (lower box)

Venereal Diseases in Australia, the U.K. and the U.S.

As noted in a recent ProMED post, the incidence of gonorrhea, syphilis and genital chlamydial infection are increasing in the United States, United Kingdom and Australia.  http://www.promedmail.org/post/6192757   I’ve compared recent trends for these diseases in the following graphs, based on data from Gideon www.GideonOnline.com [1]  Note that highest rates for all three conditions are consistently reported by the United States.

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]

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.

Disease Outbreaks due to Sprouts

As of June, 2018 the Gideon database (www.GideonOnline.com) chronicles 22,777 published Infectious Diseases outbreaks.  Sprouts were implicated in 13.4% of outbreaks which specify a disease vehicle (5.2% of salmonellosis outbreaks).  Salmonellae were responsible for 83% of outbreaks associated with sprouts.  The remainder were caused by Escherichia coli, Listeria monocytogenes or Bacillus cereus. [1]

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]
