In the Governmental District of Potsdam only those districts which bordered directly on Berlin were severely attacked by small-pox in the year 1871, e.g. the districts of Niederbarnim, Teltow, Jüterbog, Luckenwalde, and East and West Havelland; in the following years those districts bordering on Niederbarnim (as Oberbarnim, Angermünde, and Templin) also suffered severely. In the city of Potsdam two Frenchmen contracted the disease on February 6, shortly after their arrival there, and on February 19 a soldier who had accompanied them was taken sick. In April an epidemic of rather wide extent was raging in the city; the number of deaths caused by small-pox in April 1871 was 157 (34·5 per 10,000 inhabitants), and in April 1872 it was 71 (16·2 per 10,000). In the city of Brandenburg-on-the-Havel an infected French soldier arrived in February 1871; he communicated the disease to his attendant, and in that very month cases of small-pox were reported among the civil inhabitants of the city, although it was impossible to prove a connexion between them and that of the French soldier. The number of deaths, all told, was 59. The number of deaths per 10,000 inhabitants in the Governmental District of Potsdam was: 1871. 1872.
