If someone suspects contact with anthrax spores, the first step is to leave the area immediately and wash exposed skin thoroughly with soap and water, then contact emergency services or go to the nearest ER rather than waiting to see symptoms. Clothing should be removed carefully, sealed in a bag, and not shaken. Yes, there is a post-exposure prophylaxis (PEP) protocol, which involves starting preventive antibiotics (such as ciprofloxacin or doxycycline) as soon as possible—often for 60 days—and, in some cases, receiving the anthrax vaccine under public health guidance, even before symptoms appear.
