The global spread of (highly pathogenic) H5N1 in birds is considered a significant pandemic threat. While prior H5N1 strains have been known, they were significantly different from the current H5N1 strain on a genetic level, making the global spread of this new strain unprecedented. The current H5N1 strain is a fast-mutating, highly pathogenic avian influenza virus (HPAI) found in multiple bird species. It is both epizootic (an epidemic in non-humans) and panzootic (a disease affecting animals of many species especially over a wide area). Unless otherwise indicated, "H5N1" in this article refers to the recent highly pathogenic strain of H5N1. In January, Japan, Hungary, Russia, and the United Kingdom joined the list of nations seeing a resurgence of bird deaths due to H5N1. In February, Pakistan, Turkey, Afghanistan, and Myanmar joined the list and Kuwait saw its first major outbreak of H5N1 avian influenza. In March, Bangladesh and Saudi Arabia each saw their first major outbreak of H5N1 avian influenza and Ghana in May. As H5N1 continued killing many birds and a few people throughout the spring in countries where it is now endemic, in June Malaysia and Germany saw a resurgence of bird deaths due to H5N1, while the Czech Republic and Togo experienced their first major outbreak of H5N1 avian influenza. In July, France and India also saw a resurgence of bird deaths due to H5N1. January January 11, 2007: "South Korean officials say the bird flu virus had been transmitted to a human during a recent outbreak among poultry, but the person showed no symptoms of disease." January 11, 2007: "Bird flu reaches another province in southern Vietnam, spreading to flocks in two new areas in as many days. Some 20 unvaccinated chicks died suddenly over the weekend at a farm in Vinh Long province, and test results came back positive for the lethal H5N1 strain." January 12, 2007: "In Nigeria, a new outbreak of the H5N1 virus is reported in birds in Sokoto and Katsina states." January 14, 2007: "Japanese agricultural officials confirmed yesterday that the virulent H5N1 bird flu virus caused the deaths of thousands of chickens at a poultry farm in southern Japan this week [...] Japan's most recent [prior] outbreak occurred in Kyoto in 2004.". January 16, 2007: "A new outbreak of virulent bird flu is confirmed in ducks in northern Thailand -- the first such case in six months. About 100 ducks
