Review Meta Analysis[Influenza pandemic deaths in Germany from 1918 to 2009. Estimates based on literature and own calculations].
Estimation of the number of deaths as a consequence of the influenza pandemics in the twentieth and twenty-first centuries (i.e. 1918-1919, 1957-1958, 1968-1970 and 2009) is a challenge worldwide and also in Germany. After conducting a systematic literature search complemented by our own calculations, values and estimates for all four pandemics were collated and evaluated. ⋯ We have proposed plausible estimates of pandemic-related excess number of deaths for the last four pandemics as well as excess mortality in Germany. The heterogeneity among pandemics is large with a variation factor of more than 1000. Possible explanations include characteristics of the virus or host (immunity), social conditions, status of the healthcare system and medical advances.

Zika virus (ZIKV) is an emerging arbovirus of the Flaviviridae family and is related to dengue, Chikungunya, West Nile, yellow fever, and Japanese encephalitis viruses. ZIKV was first discovered in Uganda in 1947. Different species of mosquito from the Aedes genus, mainly A. aegypti and A. albopictus are the vectors responsible for ZIKV infection in humans. ⋯ However, all this is set to change with its rapid spread in the Western hemisphere and suspected complications particularly microcephaly in newborn babies with ZIKV infected mothers. ZIKV is expected to substantially add to both short-term and long-term economic burden of the effected countries. Due to the large number of people travelling across the borders and some reported cases of transmission of ZIKV via contaminated blood, screening and identification of asymptomatic infected individuals are important.
