Malaria in Syria and Turkey

Malaria rates in Turkey are not dissimilar from those reported in the United States during the 1930’s and 1940’s. The risk for importation of malaria from Syria into Turkey is minimal, given recent disease trends in the two countries (see graph) [1-3]

West Nile Fever in the United States

Following a steady decline that began ten years ago, the incidence of West Nile fever in both humans and animals has remained relatively low during the past two years. [1-3] See graph. It will be interesting to see whether these trends will continue through 2012.

United States: Recent Trends in Tick-borne Diseases

Since 1999, there has been a striking parallel among rates of reportable tick-borne diseases in the United States – see graph (Lyme disease expressed as cases per 100,000 for fit). [1,2]

Pertussis in Australia and New Zealand

Since the 1990’s, rates of pertussis in Australia and New Zealand have increased dramatically, and are currently at levels which have not been encountered in the United States for over sixty years. [1-4] See graph:

These trends do not reflect a lapse in vaccine uptake. See graph:

Coccidioidomycosis in the United States

Most of the increasing incidence of coccidioidomycosis in the United States since 2000 has consisted of cases in Arizona – see graph 1. The number of fatal cases has also increased during this period – see graph 2.

Lyme Disease – Incidence by States

Although most cases of Lyme disease in the United States were initially reported by New York, Pennsylvania and Connecticut, disease incidence in these states has not paralled a steady increase in national rates since the 1990’s (see graph). [1-3]

Tick-borne Diseases in the United States

Nine tick-borne infections affect humans in the United States. Data on a national level are available for Lyme disease, Powassan encephalitis, Rocky Mountain spotted fever, Tularemia, Granulocytic ehrlichiosis (Anaplasmosis) and Human monocytic ehrlichiosis. Statistics for three diseases (Babesiosis, Relapsing fever and Colorado tick fever) are not published. The following graph compares reporting trends for tick-borne infections (Lyme disease displayed as cases/100,000 for fit). [1,2]

Note an apparent parallel increase for some diseases during 2000 to 2008, followed by a dip during 2009 to 2010. Assuming a statistical association between these data, explanations might include changes in tick populations as a whole, or trends in human-tick contact over time.

Lyme Disease in the United Kingdom

The incidence of Lyme disease has been increasing in the United Kingdom since reporting began, with highest rates in Scotland. In the following graph I’ve contrasted these rates with those of the Uhnited States. [1]

Brucellosis in Argentina

Rates of Brucellosis in Argentina have been decreasing for over two decades, but continue to parallel those reported in the United States during the 1950’s. [1,2] See graph [3]:

Hepatitis A in North America

Notwithstanding a recent series of outbreaks, rates of Hepatitis A in Mexico have changed little since 1984, and remain similar to those reported in the United States during the 1960’s and 1970’s (see graph). [1-3]
