Assalamualaykum Is the below dua proven in sharee'ah for reading in protection from OR for curing patient of swine flue. "Allahhumma inni a'oozoobika minal junooni wal barasi wa say'yil asqaam"
All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His Slave and Messenger.
First of all, it should be noted that the supplication in question was authentically narrated from the Prophet . It was narrated on the authority of Anas, may Allah be pleased with him, that the Prophet used to say: "Allahumma inni a‘oothu bika min al-baras, wal-junoon, wal-juthaam, wa sayyi’il-asqaam (O Allah! I seek refuge in You from vitiligo, madness, leprosy and evil diseases).'' [Ahmad, Abu Daawood and An-Nasaa’i] This proves that it is permissible for a Muslim to say this supplication to seek protection or cure from every disease, whether it is swine flu or any other disease. That is because the words "evil diseases" include all of these diseases.
Allah Knows best.
