Tularemia Deaths in the United States

Rates of fatal tularemia in the United States have changed little since the 1960’s, and are similar to those reported for plague. [1]  See graph:

Japanese Encephalitis in India

The idea that most cases of “acute encephalitis” in Uttar Pradesh are caused by diseases other than Japanese encephalitis is borne out by reporting statistics.  In the following chart, note the precipitous decline in “Japanese encephalitis” incidence which followed introduction of reporting for “Acute encephalitis” in 2008 (upper graph).  This phenomenon is even more striking for India as a whole (lower graph). [1,2]

Cyclosporiasis in The United States

The following background information on Cyclosporiasis in the United States is abstracted from Gideon www.GideonOnline.com and the Gideon e-book series [1]   (Primary references are available on request)

Cyclosporiasis is the least common reportable protozoan infection in the United States.  In 2008, the reported disease rate among 10 states was 2.25 per 100,000 population.

The true incidence of food-borne cyclosporiasis in the United States has been estimated at 11,407 to 19,808 cases per year (15 hospitalizations), accounting for 0.1% of all food-borne illness. Approximately 42% of cases are imported.

1,110 individual cases of cyclosporiasis were reported during 1997 to 2008.  849 (76.5%) of the cases occurred in seven states, including 498 (44.9% of total) in Florida.  51.7% of cases with known travel history were autochthonous. {p 21471951}

No fatal cases were reported during 1998 to 2006.

Nine food-borne outbreaks (325 cases) of cyclosporiasis were reported during 1998 to 2002; 0 in 2007; 3 (66 total cases) in 2008; 1 (8 cases) in 2009; 0 in 2010.  Eleven   outbreaks (3,533 cases) related to imported food were reported during 1996 to 2014.

Reported disease rates have increased somewhat since 2012.  See graph:

As of 2017, Ross River disease and Barmah Forest disease continue to infect a considerable number of people in Queensland, Australia. In fact, rates of these two mosquito-borne viral infections in this state have changed little during the past 25 years. [1]   See graph:

Schistosomiasis in The Philippines

The following is abstracted from reference [1] and the Gideon web application www.GideonOnline.com .  Primary references are available on request.

Schistosomiasis was first reported in the Philippines in 1906, and as of 1921, an estimated 25,000 to 30,000 people were infested.  During 1944 to 1945, 1,700 cases were reported among American and Australian military personnel serving in the Philippines.

An estimated 300,000 Filipinos were infested as of 1948.  By 1970, the disease was known  to be epidemic to 24 provinces.; and as of 1975, 5 million persons were considered at risk and approximately 1 million infected.  By 2002, an estimated 800,000 were infested and 6.7 million at risk; and as of 2010, an estimated 560,000 were infested.

Reported incidence and mortality data are summarized in the following graph:

In recent years, cases have been reported from Mindoro Oriental and Sorsogon in Southern Luzon; the provinces of North, East and Western Samar; LeyteBohol in Eastern Visayas; all of Mindanao with the exception of Misamis Oriental, Davao Oriental and Maguindanao.

Schistosomiasis is most common among males, and individuals ages > 19 years.  

Notable outbreaks were reported in Davao del Sur in 2000 (222 cases as of October – most in Digos- Igpit, Colorado, and Matti barangays); and in Palo, Leyte in 2011 (99 cases)

Infestation by Schistoma japonicum is common among dogs, field water buffaloes (Carabao) and rats on Leyte.  The local snail reservoir is Oncomelania hupensis quadrasi

Tick-borne Encephalitis in the Baltic Region

Rates of Tick-borne encephalitis reported by Estonia, Latvia and Lithuania have been strikingly similar for the past two decades.  See graph [1] :

This phenomenon seems to have begun only after dissolution of the former Soviet Union, and could reflect similar ecology, weather or other regional factors.

Hepatitis E in the United Kingdom

Trypanosomiasis due to T. brucei gambiense entered Tanzania from Zaire in approximately 1902; T.b. rhodesiense from Mozambique in 1910.  As of 2004, transmission was reported in Kigoma (Kibondo and Kasulu districts), Tabora (Kigoma, Sikonge and Urambo districts), and Rukwa (Mpanda district).  Highest prevalence occurs in Arusha and Kigoma.   An estimated 1.5 million persons lived in endemic zones during the 1980’s.   For several decades, disease rates in Tanzania have paralleled those reported for Africa as a whole  (see graph) [2]

 

 

Prevalence surveys have demonstrated that 15.8% of cattle (Bos indicus) from traditional pastoral Maasai and managed Boran regions are infested; 0.7% in Monduli District, northern Tanzania.  The parasite has also been identified in 10.1% of domestic pigs in Mbulu, Arumeru and Dodoma; and in 0.010% of tsetse flies (Glossina swynnertoni and G. pallidipes) in Serengeti National Park.
