Swine Influenza A Outbreak, Fort Dix, New Jersey, 1976

چکیده
In early 1976, the novel A/New Jersey/76 (Hsw1N1) influenza virus caused severe respiratory illness in 13 soldiers with 1 death at Fort Dix, New Jersey. Since A/New Jersey was similar to the 1918-1919 pandemic virus, rapid outbreak assessment and enhanced surveillance were initiated. A/New Jersey virus was detected only from January 19 to February 9 and did not spread beyond Fort Dix. A/Victoria/75 (H3N2) spread simultaneously, also caused illness, and persisted until March. Up to 230 soldiers were infected with the A/New Jersey virus. Rapid recognition of A/New Jersey, swift outbreak assessment, and enhanced surveillance resulted from excellent collaboration between Fort Dix, New Jersey Department of Health, Walter Reed Army Institute of Research, and Center for Disease Control personnel. Despite efforts to define the events at Fort Dix, many questions remain unanswered, including the following: Where did A/New Jersey come from? Why did transmission stop?

The 1976 outbreak of A/New Jersey/76 influenza in Fort Dix is a rare example of an influenza virus with documented human to human transmission that failed to spread widely. Despite extensive epidemiological investigation, no attempt has been made to quantify the transmissibility of this virus.

متن کاملReflections on the 1976 Swine Flu Vaccination Program
In 1976, 2 recruits at Fort Dix, New Jersey, had an influenza like illness. Isolates of virus taken from them included A/New Jersey/76 (Hsw1n1), a strain similar to the virus believed at the time to be the cause of the 1918 pandemic, commonly known as swine flu. Serologic studies at Fort Dix suggested that >200 soldiers had been infected and that person-to-person transmission had occurred. We r...
متن کاملInfluenza Pandemic Periodicity, Virus Recycling, and the Art of Risk Assessment
Influenza pandemic risk assessment is an uncertain art. The theory that influenza A virus pandemics occur every 10 to 11 years and seroarcheologic evidence of virus recycling set the stage in early 1976 for risk assessment and risk management of the Fort Dix, New Jersey, swine influenza outbreak. Additional data and passage of time proved the theory untenable. Much has been learned about influe...

levels of illness but low death rates in pigs. These viruses may circulate among pigs throughout the year, but most outbreaks occur during the autumn and winter months, similar to flu outbreaks in humans. The classical swine flu virus (an H1N1 virus) was first isolated from a pig in 1930. Like all influenza viruses, swine flu viruses change constantly. Pigs can be infected by avian influenza an...

In one of his essays the late humorist, Robert Benchley, spoke of his diminishing confidence during college that he could fill an inside straight in poker. The people who try to predict major influenza outbreaks go through a similar evolution. While a cyclic recurrence of the same influenza strain can be reasonably predicted on the basis of morbidity and serological data which reflect the remai...
