ISLAMABAD - The National Institute of Health (NIH) on Friday confirmed the second consecutive case of the H1N1 (swine flu) virus in the Capital, while a blood sample of another suspected patient is being processed. Spokesman of Pakistan Institute of Medical Sciences Dr Wasim Khawaja told TheNation that Imram Khan, suffering from fever and flu, was brought to the hospital. He said that the patient (28) had arrived Pakistan from Middle East by air. He further said that the NIH confirmed Imran Khan as H1N1 positive. After admitting the patient, the PIMS administration has kept him in the isolation ward where he is being provided all possible medical treatment, he further maintained. As an advice to the general public, he said, people must cover mouth with a tissue or a handkerchief or at least with the elbow while coughing or sneezing. The only positive aspect of the situation was that there was no severity amongst the so far admitted cases as the patients health was under control after due medication, he added. Informing about the availability of anti-viral drug, Tami-flu, in Pakistan, he said that the medicine was sufficiently available in the hospital to treat any patient suffering from swine flu. Similarly another patient who arrived here on Wednesday from Sharja was also admitted in the PIMS on being diagnosed swine flu positive. Considering gravity of the situation, the PIMS administration has constituted two committees one for treating the swine flu patients and the other for infection control. Although the government has already asked all the airports in the country to scan passengers entering Pakistan, but none of these was detected at the airport. The government has also instructed crews of all arriving aircraft to be vigilant and observe passengers for signs of flu like symptoms and report to the official concerned as soon as the plane lands. Despite all these preventive instructions the patient entered the country without being noticed anywhere and eventually himself went to NIH to test his blood sample. Swine flu is a new type of H1N1 virus. This flu is a hybrid of animal, human and birds genes thus it crossed the specie barriers and become a challenge to mankind. It is worth mentioning here that swine flu is a highly contagious acute respiratory disease of pigs and the virus is spread among pigs by aerosols through direct and indirect contact, and also through asymptomatic carrier pigs. According to the independent statistics, 205,785 people were infected during the latest spree of swine flu whereas 1,569 deaths were reported worldwide.
