Preventing Smallpox
The virus is usually spread by droplets from the nose or throat of infected individuals
through direct and fairly prolonged face-to-face contact.
Infrequent transmission has occurred from aerosol and direct contact
with infected lesions, clothing, and bedding.
Individuals become infectious when lesions begin to form in the mouth,
which occurs within hours of the rash. Individuals remain infectious
until the last scab from the rash has separated.
Immunization is the best method of prevention against smallpox.
The CDC has a detailed plan to protect Americans against the use of
smallpox as a biological weapon. This plan includes rapid
immunization of exposed individuals, as well as isolation of ill
persons.
Respiratory etiquette (covering your cough or sneeze) and good hand
washing are important ways to reduce the spread of disease. |
