Management biologischer Gefahrenlagen

[Lessons learnt from the German smallpox outbreaks after World War II]

BACKGROUND

Even though smallpox was declared eradicated by WHO in 1980, it cannot be ruled out that the etiological variola virus could be used as a biological weapon. Undestroyed viruses from biowarfare programmes, virus strains left undetected in a freezer or dangerous recombinant poxvirus constructs could cause dangerous outbreaks in a relatively unprotected population.

OBJECTIVES

Despite an abundance of studies performed during the eradication of smallpox, epidemiological data for preparedness planning and outbreak control in modern, industrialized countries are scarce.

MATERIAL AND METHODS

Full-text hand search for the period from 1945 to 1975 in the main German public health journals.

RESULTS

After World War II 12 smallpox outbreaks occurred in Germany. They were studied with the focus on the period of contagiousness, the protective effect of vaccination, booster-effect of revaccination and the place of infection. A total of 95 individuals contracted smallpox, including 10 fatalities. Despite having been previously vaccinated, 81 vaccinated persons came down with smallpox, yet 91% of them developed only mild symptoms. These patients presented a high risk for spreading the infection to contact persons due to misinterpretation of symptoms and the continuing social contacts. Basically, the risk of transmission in the first 2 to 3 days after onset of symptoms was low, thus facilitating antiepidemic measures. The importance of hospital preparedness is emphasized by the fact that most infections occurred in hospitals.

CONCLUSION

The data analyzed provide valuable information for today's outbreak response planning and counter bioterrorism preparedness.

[Structural requirements for the management of patients with highly contagious life-threatening infectious diseases: update 2015]

The care of highly contagious life-threatening infectious diseases (HLID) requires specialized treatment facilities that are capable of strict isolation measures and appropriate medical treatment. The German approach to the management of these diseases, which is maintained by the Permanent Working Group of Medical Competence and Treatment Centers for Highly Contagious and Life-Threatening Diseases (STAKOB) is adjusted in the present publication with regards to recent experiences and upcoming needs. Clear synergies in using infrastructures and bundling of resources have led to similar efforts at the European level. The German concept, therefore, has a pioneering role. This update is intended to improve professional patient care and also minimize the risk of disease spread and transmission.

[Infectious disease emergencies. Responsibility of municipal, state and federal health protection authorities with reference to the international health regulations]

Pandemic preparedness has become a catch phrase for politicians, government agencies and communities, both nationally and internationally. This is due to the increasing number of infectious diseases emergencies that are important challenges for health protection authorities, which was shown impressively when SARS emerged as the first pandemic in this millennium. In Germany, effective and efficient infection control is complex, with local health protection authorities having their own responsibilities. In the case of an emergency epidemic, regional health departments are responsible. Having authority over these are authorities on the federal state level as well as on the federal level. For the European Community, the European Centre for Disease Prevention and Control (ECDC) was established. The mission of this agency is to identify, assess and communicate current and emerging threats to human health posed by infectious diseases.

Bioterrorism: is it a real threat?

The Geneva Protocol of 1925 commits the signatory nations to refraining from the use of biological weapons. However, the terrorist assaults of September 2001 and, subsequently, the anthrax-containing letters are cause for great concerns: new threats to the security of nations are expected, as terrorist organizations seem to increasingly explore novel ways of spreading terror. In this context, naturally emerging diseases such as SARS, monkeypox or West Nile fever assume new importance because it is difficult to distinguish between natural epidemics and possible bioweapon assaults. Great efforts on the part of governments and public health authorities are necessary to counteract these threats.
