Standard:<\/strong> NASA-STD-3001 Technical Brief – Health Stabilization Program V1 4.4.2.4 Overview <\/p>\n\n\n\n

Summary:<\/strong><\/p>\n\n\n\n

Health Stabilization Program (HSP) necessary for all spaceflight missions to reduce risk of infection both pre-flight and in-flight. HSP has been implemented since Apollo 14 mission. The 2 main components of HSP are pre-flight immunizations and quarantine, which have been rudimentary in managing the risk of in-flight infection, especially upper respiratory and enteric infections. Current protocol mandates HSP starts 14 days before launch. HSP only successful if there is full participation. <\/p>\n\n\n\n

After implementation of HSP, there was a noticeable reduction in illnesses and infections pre and in-flight. Before implementation of HSP, 57% of Apollo crew members experienced some extent of infectious illnesses before flight. Since implementation of HSP starting with Apollo 14, there has been a significant decrease in the risk of infectious diseases. See image below.<\/em> <\/p>\n\n\n\n

Apollo <\/strong><\/p>\n\n\n\n

  • 21 day HSP for prime and backup crew <\/li>
  • Immunizations<\/li>
  • Extensive disease exposure via quarantine
    • Limited exposure to fomites, contaminated consumables, and interpersonal contacts<\/li>
    • Crewmembers used different equipment <\/li>
    • Closed controlled living environment – ultra-high efficiency bacterial filters, positive air pressure <\/strong>(outward flow of air only), and controlled food and water intake (including microbiological testing of samples) <\/li>
    • No exposure to potential carries (eg. children, maintenance personnel); contacts restricted to medically approved individuals only (~100 people total) <\/li><\/ul><\/li><\/ul>\n<\/div><\/div>\n\n\n\n

      Skylab <\/strong><\/p>\n\n\n\n

      • 21-day pre-flight, 7-day post-flight HSP <\/li>
      • Immunizations similar to Apollo <\/li>
      • Quarantines to minimize crew exposure to infectious diseases
        • Similar to Apollo \u2013 positive air pressure,<\/li>
        • Primary contacts were inspected by a nurse before interaction with crew; interactions with non-primary contacts were performed via CCTV<\/li>
        • Food was specially prepared for the crew<\/li>
        • Additional space for isolation of an ill crewmember<\/li><\/ul><\/li>
        • Limitations were set on the number of primary contacts
          • Cited as the change that impacted the incidence of disease most<\/li><\/ul><\/li><\/ul>\n\n\n\n

            ISS<\/strong><\/p>\n\n\n\n

            • 14-day pre-flight HSP<\/li>
            • Countermeasures in place: crew and contact education; hand & respiratory hygiene; physical separation; PPE; immunizations (similar to Apollo); medical screening of contacts by a physician before crew interaction; and, avoiding tasks with a high risk of infectious disease acquisition<\/li>
            • Operating groups and personal contacts are allowed to have close crew contact, but special guests and VIPs must stay >1.5 meters away<\/li>
            • Personal contacts are limited to 2-3 people or family members (with exceptions)
              • They may be isolated prior to crew contact, depending on when they arrive at the site<\/li><\/ul><\/li><\/ul>\n\n\n\n
