The recent reports of H5N1 in bar headed geese in Gangcha and Yushu counties in Qinghai province mark the one year cycle of the spread of the Qinghai strain of H5N1. Below is a list of OIE reports filed in countries for the first time (with the exception of China) in the past 12 months. One year ago reported cases of H5N1 were limited to China and countries in Asia to the east and southeast of China.
 
The introduction of H5N1 into new countries is chronologically listed below, based on the date of the first outbreak in that country. The Qinghai H5N1 infections are somewhat larger than listed below because outbreaks in areas near prior H5N1 reports have been excluded because the new outbreaks may be due to another H5N1 strain. The countries below have reported Qinghai sequences or are adjacent to countries that have reported Qinghai sequences. Countries reporting Qinghai sequences are in bold.
 
The initial outbreak started in mid-April, but was first reported on May 9, 2005 and involved 189 bar headed geese at Qinghai Lake. 519 dead birds were described in the May 21 OIE report and the following months there were outbreaks on farms in Xinjiang. It is likely that many subsequent outbreaks in Xinjiang were the Qinghai strain, but only the Liaoning outbreak has been confirmed as the Qinghai strain. Human cases in China in late 2005 and early 2006 have been due to the Fujian strain, which was also found in Laos and Malaysia in 2006, so much of eastern Asia has several H5N1 strains co-circulating.
 
However, the countries listed below are all almost certainly infected with the Qinghai strain. None of these countries had previously reported an Asian strain of H5N1 and the reports followed the timing and path of migratory birds known t be infected with the Qinghai strain of H5N1.
 
The data below is from OIE reports, but is clearly an underestimate of the true spread and the number of species infected. Russia filed an OIE report that included two dozen species that were shot by hunters and were H5N1 positive (wild duck, laughing gull, rook, northern stover, crow, pigeon, sandpiper, oyster catcher, little grebe. black-winged stilt, phalatrope, little tern, pied wagtail, green sandpiper, white headed plover, starling, coot, mallard sparrow hawk, buzzard, turtle dove, garganey, teal). In addition, the Minister of Agriculture site indicated there had been H5N1 outbreaks in southern Russia in Astrakhan, Rostov, Kalmykia, Adygeya, North Ossetia, Kabardino-Balkaria, Chechnya, and Stavropol. Moreover, H5N1 was still present in Dagestan, Krasnodar and Volgograd,
 
Thus, the list below shows where H5N1 has been reported in OIE filings, but the data is more informative about overall surveillance and lack thereof. The positive reports including a wide range of species that are in countries in the major flyways linked to the massive outbreak in southern Siberia in the summer of 2005. Because of the number of infected species and number of positive reports, it is likely that adjacent countries are also H5N1 positive and in countries where wild birds are not included, it is likely that those wild birds are also infected.
 
Countries with the poorest surveillance are those that are adjacent to H5N1 positive countries, but are still deny H5N1 infections. Also near the bottom of the surveillance list are countries which failed to detect H5N1 in wild birds, even after domestic poultry was H5N1 infected. Next are countries who could only detect H5N1 in mute swans. H5N1 is easily detected in mute swans, but the transmission of H5N1 is generally by other species which are migratory. Next are countries which detected H5N1 in wild birds, but failed to detect H5N1 in healthy wild birds, The only country to detect H5N1 in healthy wild birds has been Russia.
 
As H5N1 transmission begin a second season of transmissions, it will be of interest to see how sequences have changed and how easily the infections are detected on the second season of spread.
