The incidence of TBE ranges from ‘only single sporadic cases’ to >50/105 per year depending on the region and on the year of analysis; it is usually 1-10/105 in endemic regions in central Europe. This number may be considered as ‘low’ – not only as an individual risk but also from a public health perspective. If an individual does contract TBE, how...

Im Alter ist die Grippe besonders gefährlich: Krankenhausaufnahmen und schwere Komplikationen sind bei infizierten Senioren häufig und die Mortalität ist erhöht. Den besten Schutz bietet die Grippeimpfung, die aber bisher in Deutschland nur jeder dritte über 60-Jährige erhält.

Background: In times of mass tourism, traveler's diarrhea is one of the most common health problems of long-distance travel. Globally, some 40 million cases occur annually. Travellers to risk areas should therefore be comprehensively advised beforehand, as to what action to take in case of an acute traveler's diarrhea and what drugs to add to thei...

The 18th meeting of the International Scientific Working Group on Tick-Borne Encephalitis (ISW-TBE)−agroup of neurologists, general practitioners, clinicians, travel physicians, virologists, pediatricians and epidemiologists−was held under the title ’Tick-borne encephalitis—still on the map’. The conference agenda was divided into six sessions: ‘Na...

Due to various activities—including those by the World Bank and the Bill & Melinda Gates Foundation—we are happy to see a global decrease in malaria cases. But too many still suffer and die from malaria so malaria prevention or at least to prevent deaths by malaria is of paramount importance, still. And this is not true for the indigenous populatio...

Jedes Jahr kehren Tausende Touristen krank von einer Fernreise zurück – Infektionen wie Darmerkrankungen, aber auch Malaria oder Dengue-Fieber sind ein gefährliches Mitbringsel. Welche Erreger lösen sie aus? Und welche Symptome sind typisch für die unterschiedlichen Auslöser der Erkrankungen?

Background: Through 2 international traveler-focused surveillance networks (GeoSentinel and TropNet), we identified and investigated a large outbreak of acute muscular sarcocystosis (AMS), a rarely reported zoonosis caused by a protozoan parasite of the genus Sarcocystis, associated with travel to Tioman Island, Malaysia, during 2011-2012. Method...

Tick-borne encephalitis (TBE) is a vector-borne disease that is primarily transmitted to humans by infected ticks and causes infection of the central nervous system. Clinical presentations range from meningitis to encephalitis with or without myelitis, and infection may result in death or long-term neurological sequelae. TBE is endemic in regions o...

Typhoid fever and other systemic Salmonella infections are severe diseases responsible for more than a hundred thousand deaths each year. Poverty and inadequate hygiene facilitate massive outbreaks, lack of medical support results in severe courses of the disease leading to complications and death. Furthermore the general situation in the areas mai...

For a long time, tick-borne encephalitis (TBE) was perceived as a risk only for the local population living in endemic areas. There was very little specific awareness and hardly any knowledge about this viral disease among doctors outside the endemic areas. Thus TBE has been a neglected travel-associated health risk. World Tourism Organization stat...

Dengue virus (DENV) is endemic in south-east Asia and Central to South America. In August 2010, a DENV infection was diagnosed in a German traveller returning from a trip to Croatia in south-east Europe. The patient presented with fever and other typical symptoms of DENV-infection. Virological investigation revealed the presence of DENV-specific Ig...

Recently there was a substantial increase in travel activities to far (including tropical) destinations. A part of these travellers is likely to import infectious diseases after their return. These cases can no more be managed by experts, only. On the other hand not every disease primarily requires diagnosis and treatment by a specialist in tropica...

Anisakiasis is caused by a fish parasite of the Nematode family. This kind of rare helminthozoonosis can mainly be found in countries where consumption of raw fish is traditionally high like Japan, the Netherlands, Pacific Islands, South Europe, Scandinavia, USA, and Canada. Man is the wrong hoste. Clinical manifestation depends on the localisation...

Snake bites by venomous snakes are a widely neglected topic despite the fact that they may cause severe tissue damages and lead to life threatening situations resulting in death mostly due to the lack of adequate medical help. Papua New Guinea hosts one of the most venomous snakes worldwide - the taipan. Medical facilities are limited, the one and...

Die Anisakiasis wird durch den Heringswurm verursacht, der zu den Nematoden zählt. Diese seltene Helminthozoonose betrifft vorwiegend Länder mit traditionell hohem Verzehr von rohem Fisch wie Japan, Niederlande, die pazifischen Inseln, Südeuropa, Skandinavien, USA und Kanada. Der Mensch stellt einen Fehlwirt dar. Das klinische Bild wird durch die L...

Standards for medical clearance for private or business missions abroad are – at least in the German speaking countries – not clearly defined and mostly derived from the old terminus "Tropentauglichkeit" which means fit for mission in the tropics. The authors now define a new standard, called "Entsendungstauglichkeitsuntersuchung" which means clear...

A group of European experts in infectious diseases and vaccinology has met on several occasions to assess the rationale for universal vaccination against rotavirus infection of infants in Europe. On the basis of the available data, we concluded that vaccination was the best approach to prevent severe rotavirus gastroenteritis, and that European cou...

The title "new vaccines" allows different approaches, such as the first option to vaccinate against a specific disease, new compositions and new ways of the application of vaccines, new target groups and indications, new combinations of compounds already on the market or new ways to trigger defense mechanisms. This article is focused on products th...

Malaria is a life threatening disease with a major impact on global health. The WHO declared an early diagnosis as one of the most important steps to fight the disease. The quality and the reliability of test results depend on the diagnostic tools used. Not every test meets the needs in every situation. PCR tests have the best sensitivity and speci...

Zusammenfassung: Bei der Fragestellung der Flugtauglichkeit bei Infektionskrankheiten ist einerseits zwischen den Zielgruppen, nämlich Piloten, Cabin Crew und Passagieren, andererseits zwischen Art und Stadium der Infektionskrankheit, nämlich akuter, chronischer Infektion und dem Zustand der Defektheilung nach Infektion zu unterscheiden. In der all...

To certify fitness for (international) air flights one must differentiate between target groups, i.e. pilots, cabin crew and passengers and the stage of infection, i.e. acute and chronic phase of disease and (organ) deficiency after infection, respectively. Publications mostly show indefinite terms which makes principles of quality assessment and i...

Einleitung Ein 7jähriges Mädchen aus Ghana wurde der infektologischen Ambulanz des Institutes für Medizi-nische Mikrobiologie und Hygiene mit der Diagnose "Enuresis nocturna" zugewiesen, die Mutter hatte den Verdacht einer Bilharziose geäußert. Die durch uns gestellte Diagnose hatte unerwartet weitreichende Foleen.

This report deals with the first diagnosed case of Vibrio cholerae non-O1 septicaemia in Austria. After a vacation in Tunisia, a 51-year-old male patient with liver cirrhosis and Billroth-II-gastrectomy was admitted to hospital because of abdominal pain, growing ascites, and jaundice. Four days later, the patient developed a single peak of high fev...

The antibiotic susceptibility of pneumococci isolated from clinical specimens from 1991 through 1994 was investigated. Of 305 strains tested by the agar dilution method, 16 (5.2%) were resistant to penicillin (MICs > or = 0.12 mg/l). Of the resistant strains, 0.3% showed high-level resistance (MIC > or = 2 mg/l). The rate of resistance to erythromy...

Increasingly, autologous blood transfusions are used in elective surgical procedures to avoid the risk of infection due to allogeneic blood transfusion. A 64-year-old patient had to undergo the implantation of a total right hip endoprosthesis. During the transfusion of 1 unit of autologous packed red cells, the patient experienced high temperature...

A study has isolated Salmonella strains from animal fodder, meal, slaughter house material and personnel, and from zoo animals. The bacteria are named and distributional data is given. -J.W.Cooper

In Sudan, the situation regarding hepatitis B is very serious. Extremely high contact rates (73.2%) and infection rates (46.9%) make swift and comprehensive countermeasures impossible. Detailed examination shows a significantly worse position for males. This begins with the problem of serum conversion and concludes with the significant tendency of...
