Pertussis: Global Trends in Incidence and Vaccine Uptake

Thursday, December 18th, 2014

Recent pertussis outbreaks are of concern, but should not overshadow a dramatic decrease in disease rates documented during the past three decades. [1] In the following chart, I’ve compared regional trends in pertussis reporting and W.H.O. estimates of vaccine uptake [2] Note that vaccine coverage has changed little since 1990.

Trichinosis: Cross-border Episodes

Sunday, December 7th, 2014

A recent trichinosis outbreak in Belgium related to Spanish boar meat reflects the continued high incidence of trichinosis in Spain. In fact, trichinosis rates in Spain are comparable to those which have not been encountered in the United States for more than 50 years [1,2] – see graph.

Measles: Still A Problem Despite Four Decades of Progress

Tuesday, November 25th, 2014

Although measles rates have declined dramatically during the past four decades, a recent upsurge reflects sub-optimal enforcement of vaccination in many countries. In the following graphs, I’ve summarized reported measles incidence and estimated vaccine uptake by region. Note that vaccination rates remain below 80% in three W.H.O. regions (African, Eastern Mediterranean and Southeast Asian), while they exceed 90% in the other three (European, American and Western Pacific) [1.2]

Campylobacteriosis in Iceland

Wednesday, August 6th, 2014

A recent posting in ProMED belies the fact that Iceland reports the lowest rates of campylobacteriosis in that region of Europe. [1-2] See graph [3] Note that an earlier outbreak (436 cases) was reported in 1999.

Deaths from Rocky Mountain Spotted Fever

Friday, June 27th, 2014

During 1961 to 1970, 207 deaths were ascribed to Rocky Mountain spotted fever (RMSF); and an estimated 612 patients died of the disease during 1983 to 1998. The highest mortality, 50 cases, was reported in 1970. In recent years, the case-fatality rate for RMSF has remained fairly constant at 0.4% to 0.8%. Among the tick-borne infections, Lyme disease has now eclipsed RMSF as a cause of death in the United States – see graph [1, 2]

Pasteurellosis in England and Wales

Sunday, April 20th, 2014

Few countries publish reports of Pasteurella multocida infection on a national level. The incidence of human pasteurellosis in the United Kingdom increased from 172 cases in 1972, to 426 in 2006 and 466 in 2007. Five fatal cases were reported during 1993 to 2006. Reporting trends for P. multicida infection in England and Wales are depicted in the following graph:

Botulism in Italy

Sunday, March 30th, 2014

The following background information of botulism in Italy was abstracted from Gideon www.GideonOnline.com and the Gideon e-book series. [1,2] (primary references are available on request).

Botulism has been a notifiable disease in Italy since 1975. Mean disease rates are similar to those reported in the United States – see graph [3] :

Botulism-Italy

Vegetable preserves are implicated in 57% of cases, and ham and sausage in 15%. Recent outbreaks have been related to mushrooms in oil, pickled olives, fresh-cheese mascarpone and roasted eggplant in oil.

In 2012, a man in England acquired botulism from imported Italian olives.

Three cases of wound botulism were reported during 1988 to 1998; and the first report of wound botulism in an injecting drug user was published in 2010.

26 cases of infant botulism (and 3 of adult intestinal botulism) were reported during 1984 to 2006 (including 6 cases due to Clostridium butyricum toxin). Type A botulism accounted for 4 casers and type B for 17.

Only two outbreaks (5 cases, 1 fatal) of botulism were reported in Italy during 1903 to 1922. Five outbreaks were reported in 1998 alone.

Notable outbreaks:
1993 – Outbreaks (7 cases, in two outbreaks) of botulism were associated with commercially prepared roasted eggplant in oil.
1995 (publication year) – An outbreak was associated with consumption of home-cured ham.
1996 – An outbreak (8 cases) was ascribed to “tiramisu” which contained contaminated mascarpone cream cheese.
2004 – An outbreak (25 cases, 0 fatal) was caused by green olives served by a restaurant in Molise.
2011 – An outbreak (3 cases, 1 fatal) of botulism in Finland was caused by imported jarred olives from Italy.
