Lyme disease in the Baltic region

Tuesday, June 26th, 2007

Steve is quoted in ProMED again:

A recent ProMED-mail posting is a reminder that Lyme disease is extremely common in the Baltic region. In fact, disease rates are several fold higher in this area than in the USA (see graph at http://exhibit.gideononline.com/Lyme-Baltic.jpg).

Additional background data abstracted from GIDEON (primary references available on request):

The 1st cases (3) of Lyme borreliosis in Lithuania were diagnosed in 1987; and Estonia reported its 1st cases in 1988.
Endemic foci exist in the western, eastern, and southern regions of Estonia. The areas of highest risk are concentrated along the Finnish Gulf coast in Harjumaa and Western Virumaa, in Parnumaa and Eastern Virumaa counties, and on the island of Saaremaa.
In Latvia, 2.7 per cent of workers in high-risk occupations and 3 per cent of healthy persons in the Karksi Nuia region (south) of Estonia are seropositive.
_Ixodes ricinus_ is abundant in Estonia, and _Ixodes persulcatus_ is found in the east and south of the country; 3 per cent of _I. ricinus_ adults and 5 per cent of the _I. persulcatus_ adults are infected with _Borrelia burgdorferi_; 31 per cent in Narva-Joesuu, 12 per cent in Western Virumaa, and 14 per cent in Tartumaa. Borreliae are found in 15 per cent of ticks (_I. ricinus_) on Vormsi Island. Tick infection by _B. afzelii_ and _B. garinii_ has also been demonstrated.
_B. afzelii_ is the dominant species among _I. ricinus_ and _I. persulcatus_ in Latvia, followed by _B. garinii_ and _B. burgdorferi_ (1993 to 2002). In Lithuania, 11 per cent of adults and 1 per cent of nymphal _I. ricinus_ ticks are infected with Borrelia (1988 to 1991).

Taiwan, Russia and measles

Monday, June 18th, 2007

In another discussion on measles on the ProMED mailing list - this time in Taiwan - a great reference to the information available in GIDEON, which complements the information available from Taiwan’s CDC:

… according to the Global Infectious Disease & Epidemiology Network - GIDEON, the numbers of clinical cases of measles reported annually in Taiwan were: 1386 in 1988; 44 in 1990; 303 in 1992; 71 in 1993; 101 in 1994; 40 in 1995; 49 in 1996; 63 in 1997; 49 in 1998; 23 in 1999; 48 in 2000; 59 in 2003; 36 in 2004; 39 in 2005; 24 in 2006 — available at http://www.gideononline.com) Taiwan has undertaken the goal of measles elimination by 2010. Data available at the website review a vaccination coverage of the cohort born in 2002 of 95 percent with MMR 1st dose. No information was available on 2nd dose coverages.

A note about Russia and measles also references GIDEON.

Linking between modules

Wednesday, June 6th, 2007

We’re continuing our progress in making it easier to find the information you’re looking for in GIDEON with minimal effort. We have added a new feature in the Microbiology module that link relevant organisms to their drug susceptibility and appropriate vaccines as demonstrated by the highlighted links in this screen shot of the Vibrio Cholerae general tab:
Microbiology Vibrio Cholerae information
These new links are in addition to links added in the past connecting between disease organisms to microbiology and typical therapy to drugs, vaccines and pathogens.
For example see the links from the Anthrax disease general information tab screen shot below, to the Microbiology organism (Bacillus anthracis), Therapy (eg: Ciprofloxacin) and Anthrax vaccine:

Background on Measles in Congo

Monday, June 4th, 2007

Steve is quoted once again in ProMED:

The latest outbreak of Measles - Democratic Republic of the Congo (Katanga) highlights the fact that measles rates in this area have changed little during the past 2 decades.
The relevant data extracted from the GIDEON database can be viewed in graphic form via the following link.
There is little doubt that such outbreaks are related to continued suboptimal and erratic vaccination coverage.
