Janet Parker

Parker was born in March 1938, and was the only daughter of Frederick and Hilda Witcomb (née Linscott). She was married to Joseph Parker, a Post Office engineer, and lived in the Kings Norton area of Birmingham. After several years as a police photographer, she joined the University of Birmingham Medical School, where she was employed as a medical photographer in the Anatomy Department. She often worked in a darkroom above the laboratory where research on smallpox viruses was being conducted.

On 11 August 1978, Parker (who had been vaccinated against smallpox in 1966, but not since) fell ill; she had a headache and pains in her muscles. She developed spots that were thought to be a benign rash, or chickenpox. On 20 August at 3pm, she was admitted to East Birmingham Hospital and a clinical diagnosis of Variola major, the most serious type of smallpox, was made by consultant Alasdair Geddes. By this time the rash had spread and covered all Parker's body, including the palms of her hands and soles of her feet, and it was confluent (i.e. the lesions had merged) on her face. At 10pm she was on her way to Catherine-de-Barnes Isolation Hospital near Solihull. By 11pm all her close contacts, including her parents, were placed in quarantine. Her parents were later also transferred to Catherine-de-Barnes. The next day, poxvirus infection was confirmed by Henry Bedson, then Head of the Smallpox laboratory at the Medical School, by electron microscopy of vesicle fluid, which Geddes had sampled from Parker's rash. Samples of the fluid were also collected by a biomedical scientist for examination at the Regional Virus Laboratory, which was in East Birmingham Hospital. Parker died of smallpox at Catherine-de-Barnes on 11 September 1978. She was the last recorded person to die from smallpox. Special disease control measures had to be put into place for Parker's funeral. Ron Fleet from Sheldon, who at the time of Parker's death worked for Solihull funeral director Bastocks and later for the BBC at Pebble Mill, recalled that he was told that authorities "would not allow the body to be stored in a fridge in case the virus managed to multiply": Concerns over the survival of infectious virus in Parker's body were well-founded, and at the inquest the coroner, who signed Parker's cremation certificate, disallowed an autopsy for safety reasons. • Illustration — The rear of the Medical School showing the location of the smallpox laboratory (bottom) and the rooms where Parker worked (above)

Many people had close contact with Parker before she was admitted to hospital. The outbreak prevention response included 260 people being immediately quarantined, several of them at Catherine-de-Barnes Hospital, including the ambulance driver who transported Parker. More than 500 people who had been (or had possibly been) in contact with Parker were given vaccinations against smallpox. On 26 August, health officials went to Parker's house in Burford Park Road, Kings Norton, and fumigated her home and car. On 28 August, five hundred people were placed in quarantine in their homes for two weeks. Parker's mother contracted smallpox on 7 September, despite having been vaccinated against the disease on 24 August. Her case was described as "very minor" and she was subsequently declared free from infection and was discharged from hospital on 22 September. Other than Parker's mother, no further cases occurred. The other close contacts, which included two biomedical scientists from the Regional Virus Laboratory, were released from quarantine in Catherine-de-Barnes on 10 October 1978. Birmingham was declared officially free of smallpox on 16 October 1978. In October 1979, the university authorities fumigated the Medical School East Wing. The ward at Catherine-de-Barnes Hospital in which Parker had died was still sealed off five years after her death, all the furniture and equipment inside left untouched.

A = smallpox laboratory; B = animalpox laboratory; C = tissue culture laboratory; E = corridor with swing barrier; D = internal service ducts with access hatches. The position of two safety cabinets is shown at the top with extraction ducts to the windows (black arrows). The circles represent centrifuges and the squares various incubators and refrigerators. The laboratory was about 9.5 metres wide. An official government inquiry into Parker's death was conducted by a panel led by microbiologist R.A. Shooter, and comprising Christopher Booth, Sir David Evans, J.R. McDonald, David Tyrrell and Sir Robert Williams, with observers from the World Health Organization (WHO), the Health and Safety Executive and the Trades Union Congress. • Illustration — Schematic diagram of the East Wing of Birmingham University Medical School in 1978. The positions of the ventilation ducts are labelled A, B, C and D. The inquiry's report noted that Bedson had failed to inform the authorities of changes in his research that could have affected safety. Shooter's enquiry discovered that the Dangerous Pathogens Advisory Group had inspected the laboratory on two occasions and each time recommended that the smallpox research be continued there, even though the facilities at the laboratory fell far short of those required by law. Several of the staff at the laboratory had received no special training. Inspectors from the WHO had told Bedson that the physical facilities at the laboratory did not meet WHO standards, but had nonetheless recommended only a few changes in laboratory procedures. Bedson misled the WHO about the volume of work handled by the laboratory, telling them that it had progressively declined since 1973, when in fact it had risen substantially as Bedson tried to finish his work before the laboratory closed. Shooter also found that while Parker had been vaccinated, it had not been done recently enough to protect her against smallpox. A foreword by the Secretary of State for Social Services, Patrick Jenkin, noted that the University of Birmingham disputed the report's findings. The report concluded that Parker had been infected by a strain of smallpox virus called Abid (named after the three-year-old Pakistani boy from whom it had originally been isolated), which was being handled in the smallpox laboratory during 24–25 July 1978. It found that there was "no doubt" that Parker had been infected at her workplace, and identified three possible ways in which this could have occurred: air current transmission; personal contact; or contact with contaminated apparatus. The report favoured air current transmission and concluded that the virus could have travelled in air currents up a service duct from the laboratory below to a room in the Anatomy Department that was used for telephone calls. On 25 July, Parker had spent much more time there than usual ordering photographic materials because the financial year was about to end. Since Shooter's Report potentially played an important role in the court case against the university for breach of safety legislation, its official publication was postponed until the outcome of the trial was known, and it was not published until 1980. Once it was published, it had a significant impact. Shooter's report was debated by Parliament. Nicolas Hawkes wrote, in 1979, that: Shooter's report was leaked to the press by Clive Jenkins, the general secretary of the trade union to which Mrs. Parker belonged. Shooter's report is one of the most damning documents ever produced by an official enquiry in Britain.

On 1 December 1978, the Health and Safety Executive announced their intention to prosecute the university for breach of safety legislation. The case was heard in October 1979 at Birmingham Magistrates' Court. Although the source of infection was traced, the mode and cause of transmission was not. Evidence presented by several internationally recognised experts, including Kevin McCarthy, Allan Watt Downie and Keith R. Dumbell, showed that airborne transmission from the laboratory to the telephone room where Parker was supposedly infected was highly improbable. The experts calculated that it would require 11812 impgal of virus fluid to have been aspirated (meaning, in this context, removed by suction of fluid and cells through a needle) and it would take 20,000 years for one particle to travel to the telephone room at the rate the fluid was aspirated. It was additionally found that although the Shooter Inquiry noted the poor state of the duct sealing in the laboratory, this was caused after the outbreak by engineers fumigating the laboratory and ducts. The university was found not guilty of causing Parker's death.

In August 1981, following a formal claim for damages made by the trade union Association of Scientific, Technical and Managerial Staffs in 1979, Parker's husband, Joseph, was awarded in compensation.

Although it seems clear that the source of Parker's infection was the smallpox virus grown at the University of Birmingham Medical School laboratory, it remains unknown how Parker came to be infected. Shooter's criticisms of the laboratory's procedures triggered radical changes in how dangerous pathogens were studied in the UK, but the inquiry's conclusions on the transmission of the virus have not been generally accepted. Professor Mark Pallen, who wrote a book about the case, said that the air duct theory "was not really believed by anyone in the know". Brian Escott-Cox QC, who successfully defended the university in the subsequent prosecution, said in 2018: In light of this incident, all known stocks of smallpox were destroyed or transferred to one of two WHO reference laboratories which had BSL-4 facilities: the Centers for Disease Control and Prevention (CDC) in the United States and the State Research Center of Virology and Biotechnology VECTOR in Koltsovo, Russia. At the time of the outbreak, the WHO had been about to certify that smallpox had been eradicated globally. It eventually did so in 1980.

On 5 September 1978, Parker's 71-year-old father, Frederick Witcomb, of Myrtle Avenue, Kings Heath, died while in quarantine at Catherine-de-Barnes Hospital. He appeared to have died following a cardiac arrest when visiting his daughter. No post-mortem was carried out on his body because of the risk of smallpox infection. On 6 September 1978, Henry Bedson, head of the Birmingham Medical School microbiology department, cut his throat in the garden shed while in quarantine at his home in Cockthorpe Close, Harborne. He died at Birmingham Accident Hospital a few days later. His suicide note read: I am sorry to have misplaced the trust which so many of my friends and colleagues have placed in me and my work. In Bedson's Munk's Roll biography published by the Royal College of Physicians, virologist Peter Wildy and Sir Gordon Wolstenholme wrote:
