Tularemia in Switzerland

The incidence of tularemia in Switzerland has increased dramatically during the past decade.  As depicted in the following chart, disease rates in this country (per 100,000 population) are currently ten-fold those reported by bordering countries.  [1-3]

Cave Fever in the United States and Israel

In 2017, several cases of relapsing fever in Texas were reported among cave workers.  The Israeli equivalent of the disease is in fact known as “cave fever” with most cases reported among tourists in caves. [1,2]  Notably, an American tourist acquired “cave fever” in Israel in 1988.  The regional pathogen, Borrelia persica is found in approximately ten percent of caves, and is transmitted by Ornithodorus tholozani, an argassid (“soft”) tick.  The annual incidence has remained fairly stable at 5 to 15 cases for the past five decades.

Measles Rates vs. Vaccine Coverage

For many years, rates of measles (per 100,000 population) reported by the  WHO European and Americas Regions have been similar. During the same period, both regions have maintained high uptake of measles vaccine. [1,2] In the following graph, I’ve contrasted these figures with those of Africa, which continues to report both high measles rates and inadequate vaccine usage.

Listeriosis in the European Union

A recent series of outbreaks in Europe reflects an increasing incidence of listeriosis in the region.  In the following graph I’ve contrasted disease rates per 100,000 in the European Union with those of the United States [1,2] :

Varicella Vaccination in the United States

For over 50 years, deaths due to varicella in the United States have exceeded deaths from measles, mumps and rubella.  The introduction of varicella vaccine during 1995 to 1996 was followed by a marked decline in mortality rates. [1,2]  See graphs below [3]

Scrub Typhus in Thailand

Rates of scrub typhus [ST] in Thailand have been increasing dramatically since the 1970’s.  In fact, the reported incidence of ST in this country is now higher than those of Hepatitis A, Leptospirosis, Melioidosis, Typhoid and even Shigellosis (chart A, below).  Among Asian countries, only south Korea reports higher rates of ST (chart B); and the disease is currently more common in Thailand than are comparable rickettsial diseases in the United States and in my own country (chart C).   In preparing these figures, I was also struck by the similarity in numbers of fatal ST cases reported in Thailand vs. fatal RMSF cases in the United States (chart D). [1-3]

Cryptosporidiosis in Ireland

The reported incidence of cryptosporidiosis in Ireland is higher than those of salmonellosis, shigellosis and giardiasis.  In fact, cryptosporidiosis is more common in this region than in the United States. [1,2]

Rickettsial Spotted Fever: United States vs. Brazil

A higher case / fatality ratio for reported spotted fever cases in Brazil vs. the United States suggests that the Brazilian strain of Rickettsia rickettsii is more virulent.  In the following charts I’ve compared data for disease incidence and deaths for each of the countries, and contrasted death rates per 100,000 population. [1,2]

Salmonellosis Rates in Western Europe

In 1993, reported rates of salmonellosis in France and bordering countries ranged from approximately 18-to-240 per 100,000.  By 2003, corresponding figures had narrowed to 15-to-120 per 100,000,  and as of 2016 were only 8-to-30 per 100,000.  (see graph) [1,2]

Diphtheria in Bangladesh and Myanmar

An outbreak of diphtheria has been reported in Bangladesh among Royingya refugees from Myanmar – two countries which have experienced similar histories of disease incidence and vaccination uptake for several decades (see graph). [1,2]
