Prevention of viral hemorrhagic fever Prevention of viral hemorrhagic fever Prevention of viral hemorrhagic fever is similar for the different viruses. There are a number of different viral hemorrhagic fevers including Ebola virus disease, Lassa fever, Rift valley fever, Marburg virus disease, Crimean-Congo haemorrhagic fever (CCHF) and yellow fever. Lassa, Ebola, Marburg and CCHF can be spread by direct contact with the body fluids of those infected. Thus the content here covers the prevention of Ebola. The use of standard precautions is recommended with all patients in a healthcare environment. This includes a minimum level of standard precautions for use with all people regardless of
Influenza A virus capable of infecting humans efficiently, or how many mutations would render an influenza virus a pandemic strain, is difficult to predict. We have examined sequences from the 1918 strain, which is the only pandemic influenza virus that could be entirely derived from avian strains. Of the 52 species-associated positions, 16 have residues typical for human strains; the others remained as avian signatures. The result supports the hypothesis that the 1918 pandemic virus is more closely related to the avian influenza A virus than are other human influenza viruses." Human flu symptoms usually include fever, cough, sore throat, muscle aches, conjunctivitis
