Incubation Period |
Diagnostic Specimens and Procedures |
Isolation Precautions |
Treatment |
Postexposure Prophylaxisa |
Comments |
Alphaviruses (VEE, EEE, and WEE) |
2-10 days |
Cerebrospinal fluid (CSF) for viral isolation, antibody detection in CSF and acute and convalescent serum |
Standard; respiratory precautions for WEE virus |
Supportive |
Protection from mosquito vectors |
|
Anthrax |
1-60 days |
Gram stain of buffy coat, CSF, pleural fluid, swab of skin lesion; culture of blood, CSF, pleural fluid, skin biopsy |
Standard; contact for skin lesions |
Ciprofloxacinb or doxycyclinec; combine with one or two additional antimicrobial agents for inhalational, gastrointestinal (GI), or oropharyngeal diseased |
Ciprofloxacinb, doxycyclinec, or amoxicilline; anthrax vaccine |
Additional antimicrobial agents to be used for inhalational, GI, or oropharyngeal disease include rifampin, vancomycin, penicillin, ampicillin, chloramphenicol, imipenem, clindamycin, and clarithromycin |
Botulism |
Foodborne: 2 hr-8 days
Inhalational: 24-72 hr |
Toxin detection from serum, feces, enema fluid, gastric fluid, vomitus, or suspected food samples; culture of feces or gastric sections; nerve conduction testing |
Standard |
Supportive care; mechanical ventilation and parenteral nutrition may be required; equine botulism antitoxin given as soon as possible (CDC)f |
|
Type-specific antitoxin should be administered when possible; antitoxin prevents additional nerve damage but does not reverse existing paralysis |
Brucellosis |
5-60 days |
Culture of blood or bone marrow; acute and convalescent serum for antibody testing |
Standard; contact for draining skin lesions |
Doxycyclinec and rifampin; if younger than 8 yr old, use TMP-SMX |
Doxycyclinec and rifampin |
TMP-SMX may substitute for rifampin with doxycycline |
Plague |
2-4 days |
Culture or fluorescent antibody staining of blood, sputum, lymph node aspirate |
Droplet |
Streptomycin sulfate or gentamicin sulfate; doxycyclinec or tetracyclinec |
Doxycyclinec; tetracyclinec |
TMP-SMX is an alternative; chloramphenicol for meningitis |
Q fever |
10-40 days |
Acute and convalescent serum samples |
Standard |
Doxycyclinec or tetracyclinec |
Doxycyclinec or tetracyclinec |
Chloramphenicol is an alternative for treatment or prophylaxis |
Smallpox |
7-19 days |
Culture of pharyngeal swab of skin lesions |
Airborne, contact |
Supportive care |
Vaccine if administered within 4 days |
|
Staphylococcal enterotoxin B |
3-12 hr |
Serum, urine, and respiratory secretions for toxin; acute and convalescent serum for antibodies |
Standard |
Supportive care |
None available |
|
Ricin |
4-8 hr |
Serum and/or respiratory secretions for enzyme immunoassay |
Standard |
Supportive care; gastric lavage and cathartics if toxin is ingested |
Protective mask |
|
Viral hemorrhagic fevers |
6-17 days |
Culture and/or antigen detection of blood and other body tissuesg; serum for acute and convalescent antibody detection |
Standard, droplet, and contact precautionsh |
Ribavarin IV for Lassa fever; plasma from convalescent patients for Argentinean hemorrhagic fever; supportive care |
