2001 anthrax attacks - Wikipedia
Oropharyngeal anthrax is less common than the gastrointestinal form. It is also associated with the ingestion of contaminated meat. Initial symptoms include cervical edema and local lymphadenopathy, which cause dysphagia and respiratory difficulties. Lesions can be seen in the oropharynx and usually have the appearance of pseudomembranous ulcerations. This form is milder than the classic gastrointestinal disease and has a more favorable prognosis.
Anthrax is a virulent, contagious, and potentially fatal disease
Inhalational anthrax is usually fatal, even with aggressive antimicrobial therapy. It appears that only about one fifth of those who contracted inhalational anthrax in Sverdlovsk recovered. Anthrax spores are about 1 to 2 μm in diameter, a size that is optimal for inhalation and deposition in the alveolar spaces. Although the lung is the initial site of contact, inhalational anthrax is not considered a true pneumonia. In most but not all cases, there is no infection in the lungs. Rather, the endospores are engulfed by alveolar macrophages and transported by them to the mediastinal and peribronchial lymph nodes, with the spores germinating en route. Anthrax bacilli multiply in the lymph nodes, causing hemorrhagic mediastinitis, and spread throughout the body in the blood.
