The exact number of deaths from anthrax is unknown, but it is estimated to be in the thousands. Anthrax is an infectious disease caused by the bacterium Bacillus anthracis. It can affect both humans and animals and is most commonly transmitted through contact with infected animals or animal products. It can also be spread through inhalation of contaminated dust or through ingestion of contaminated food or water.
Based on available data, there have been more than 2,000 reported cases of anthrax since 1900. In the United States, the majority of deaths from anthrax have been caused by inhalation of the spores, with an estimated total of 176 people killed by inhalational anthrax since 1900. The majority of these cases occurred during the 2001 anthrax attacks in the United States, in which 22 people were killed.
Outside of the United States, the majority of reported anthrax cases and deaths have been caused by ingestion of contaminated food or water. There have been at least 1,000 reported deaths from ingestion anthrax since 1900, with the majority of these occurring in developing countries.
In conclusion, it is estimated that thousands of people have died from anthrax since 1900. The majority of deaths in the United States have been from inhalation of the spores, while the majority of deaths outside of the United States have been from ingestion of contaminated food or water.
