Surgery or facilities for complex childbirth are therefore limited, and emergencies can necessitate communicating with passing fishing vessels so the injured person can be ferried to Cape Town. As of late 2007, IBM and Beacon Equity Partners, co-operating with Medweb, the University of Pittsburgh Medical Center and the island's government on "Project Tristan", had supplied the island's doctor with access to long distance tele-medical help, making it possible to send EKG and X-ray pictures to doctors in other countries for instant consultation. The Camogli Healthcare Centre, usually referred to as the hospital, was built and equipped in 2016/2017 to the latest UK National Health Service standards and was officially opened on 7 June 2017. It is located in the southwestern corner of the settlement below the previous hospital (built in 1971), which is now used by the veterinarians and for general storage. The new hospital was funded by the UK Department for International Development with the intention the improved facilities would allow more procedures to be performed locally by visiting specialists, and therefore reduce the need for expensive referrals to Cape Town. There are normally two expatriate doctors on the island, who provide 24 hour cover. There are also normally two expatriate and four local nurses, as well as two dental technicians, a hospital manager and ancillary staff. The medical staff deal with day-to-day medical matters, handle emergency cases, and undertake minor surgery. More complex and serious cases are transported to Cape Town for treatment, as are all expectant mothers for their deliveries. There are instances of health problems attributed to endogamy, including glaucoma. In addition, there is a very high (42%) incidence of asthma among the population and research by Noe Zamel of the University of Toronto has led to discoveries about the genetic nature of the disease. Three of the original settlers of the island had asthma. Culture Music and traditional dance Tristan residents Mary Swain and Percy Lavarello were recorded in 1962 whilst evacuated in Calshot, Hampshire by Maud Karpeles and Peter Kennedy singing traditional songs and discussing the culture of the island, mainly music and dance; the full recording (split between seven tapes and also including other Tristan residents) can be heard on the British Library Sound Archive website. On these tapes, Mary Swain sings traditional English folk songs learnt from her mother, including seventeenth-century Child Ballads such as "Barbara Allen" and "The Golden Vanity". She
