CDC confirmed cases of anthrax

Based on a rigorous case definition, CDC is reporting 15 confirmed cases of anthrax: 2 in Florida, 3 in New York City, 5 in New Jersey, and 5 in Washington, D.C. (in collaboration with MD and VA). CDC is also reporting 4 suspect cases: 3 in New York City and 1 in New Jersey.

CDC defines a confirmed case of anthrax as 1) a clinically compatible case of cutaneous, inhalational, or gastrointestinal illness that is laboratory confirmed by isolation of B. anthracis from an affected tissue or site or 2) other laboratory evidence of B. anthracis infection based on at least two supportive laboratory tests.

New Jersey case confirmation

A confirmed case of cutaneous anthrax has been identified in a New Jersey resident whose occupation is not directly linked to the mail delivery system. The patient was discharged from the hospital yesterday, is on antibiotic treatment, and is doing well.

This case is under active and intense investigation by public health and law enforcement officials working with the postal service. The investigation will examine a range of possibilities including possible links between this case and the Hamilton mail facility.

Steps being taken immediately include:

  • extensive interviews;

  • environmental sampling in the patient’s home and workplace;

  • environmental sampling of pathways between the Hamilton mail facility and locations where the patient receives mail; and

  • evaluation of other potential sources of exposure.

  • While it is not possible to eliminate the risk of anthrax, the risk to the general public is low and can be further reduced by being alert for suspicious packages and by handwashing after opening the mail. Heightened public health surveillance continues and has been intensified so that anthrax can be promptly recognized and treated.

    While the risk is considered to be very low to individuals from possible contamination in the mail, people should continue to be alert for suspicious mail.

    Mail might be considered suspicious if it is:

  • Sent by someone you don’t know

  • Addressed to someone no longer at your address

  • Handwritten with no return address or one that you cannot confirm as legitimate

  • Lopsided or lumpy in appearance.

  • Sealed with excessive amounts of tape.

  • Marked with restrictive endorsements such as personal or confidential.

  • Has excessive postage.

  • Dos and Don’ts for suspicious letters


    Don’t -

  • Shake or empty the contents.

  • Carry the package or envelope, show it to others, or allow others to examine it.

  • Do -

  • Put the package or envelope on a stable surface; do not sniff, touch, taste, or look closely at it or any contents that may have spilled.

  • Alert others in the area about the suspicious package or envelope. Leave the area, close any doors, and take actions to prevent others from entering the area. If possible, shut off the ventilation system.

  • Wash hands with soap and water to prevent spreading potentially infectious material to face or skin. Seek additional instructions for exposed or potentially exposed persons.

  • If at work, notify a supervisor, a security officer, or a law enforcement official. If at home, contact the local law enforcement agency.

  • If possible, create a list of persons who were in the room or area when this suspicious letter or package was recognized and a list of persons who may have handled this package or letter. Give the list to both the local public health authorities and law enforcement officials.

  • Cutaneous anthrax is a boil-like skin lesion that eventually forms an ulcer with a black center or crust (similar in appearance to some spider bites).

    The cutaneous form of anthrax responds well to antibiotics if treatment is started soon after symptoms appear, such as in this case.

    Individuals should, especially in areas that have been directly affected, review and be familiar with advice provided to all postal patrons by the US Postal Service and follow that advice.
