Rh by the Board of Health of Alexandria and isolated a sufficient length of time to complete the observation period of five days. Their soiled linen and wearing apparel shall be disinfected. They shall then receive pratique.

Vessels having had a run of less than seven days without infection and desiring to obtain pratique in Egypt shall be detained in an establishment designated by the Board of Health of Alexandria for a sufficient length of time to complete the observation period of five days. They shall undergo the measures prescribed for infected vessels.

When the plague or cholera has appeared exclusively among the crew, only the soiled linen of the latter shall be disinfected, but it shall all be disinfected, including that in the living quarters of the crew.

61. Infected vessels are divided into vessels with a physician and a disinfecting apparatus (chamber) on board, and vessels without a physician and a disinfecting apparatus (chamber).

a) Vessels without a physician and a disinfecting apparatus (chamber) shall be stopped at Moses Spring; persons showing symptoms of plague or cholera shall be landed and isolated in a hospital. The disinfection shall be carried out in a thorough manner. The other passengers shall be landed and isolated in groups composed of as few persons as possible, so that the whole number may not be infected by a particular group if the plague or cholera should develop. The soiled linen, wearing apparel, and clothing of the crew and passengers, as well as the vessel, shall be disinfected.

It is to be distinctly understood that there shall be no discharge of cargo but simply a disinfection of the part of the vessel which has been infected.

The passengers shall remain for five days in an establishment designated by the Sanitary, Maritime, and Quarantine Board of Egypt. When the cases of plague or cholera date back several days, the length of the isolation shall be diminished. This length shall vary according to the date of the cure, death, or isolation of the last patient. Thus, when the last case of plague or cholera has terminated six days before by a cure or death, or when the last patient has been isolated for six days, the observation shall last one day; if only five days have elapsed, the observation period shall be two days; if only four days have elapsed, the observation period shall be three days; if only three days have elapsed, the observation period shall be four days; and if only two days or one day has elapsed, the observation period shall be five days.

b) Vessels with a physician and a disinfecting apparatus (chamber) on board shall be stopped at Moses Spring. The ship's physician must declare, under oath, what persons on board show symptoms of plague or cholera. These patients shall be landed and isolated.
