Métras, R.Abdu, P.Okike, I.Stevens, K.Costard, S.Grace, DeliaPfeiffer, Dirk U.Randolph, Thomas F.[Risk factors for the occurrence of highly pathogenic avian influenza H5N1 in Nigeria: Results of a case-control study conducted in April and May 2009 in Kano and Lagos States]Risk factors for the occurrence of highly pathogenic avian influenza H5N1 in Nigeria: Results of a case-control study conducted in April and May 2009 in Kano and Lagos States

We quantified the between-village transmission rate, β (the rate of transmission of H5N1 HPAI virus per effective contact), and the reproductive number, Re (the average number of outbreaks caused by one infectious village during its entire infectious period), of H5N1 highly pathogenic avian influ...


Bett, Bernard K.Henning, J.Abdu, P.Okike, I.Poole, Elizabeth J.Young, J.Randolph, Thomas F.Perry, Brian D.[Transmission rate and reproductive number of the H5N1 highly pathogenic avian influenza virus during the December 2005-July 2008 epidemic in Nigeria]Transmission rate and reproductive number of the H5N1 highly pathogenic avian influenza virus during the December 2005-July 2008 epidemic in Nigeria

Outbreaks of highly pathogenic avian influenza (HPAI) H5N1 occurred in Nigeria between December 2005 and July 2008. We describe temporal and spatial characteristics of these outbreaks at State and Local Government Area (LGA) levels. A total of 25 of 37 States (67.6%; Exact 95% CI: 50.2–82.0%) and...

Since the first reported outbreak of highly pathogenic avian influenza (HPAI) H5N1 in Nigeria in 2006, there have been approximately 300 reported cases as at the end of August 2008, of which more than half occurred on backyard commercial farms. A case-control study was conducted in the two states...

Highly Pathogenic Avian Influenza (HPAI) is classified by the World Organization for Animal Health as one of the notifiable diseases. Its occurrence is associated with severe socio-economic impacts and is also zoonotic. Bangladesh HPAI epidemic data for the period between 2007 and 2013 were obtai...
