A total of 31 people have been infected this month with the H5N1 strain of the bird flu, Egypt’s Ministry of Health announced Tuesday. So far, 10 have died from the virus. The rate of infection appears to be higher than it was in 2014, when 27 infections and 11 fatalities were reported.

Meanwhile, in Nigeria, 11 out of the country’s 36 states have reported cases of the bird flu. Nigerian Agricultural and Rural Development Minister Akinwumi Adesina said Thursday, “At the time of my briefing the nation on Jan. 21, 2015, seven states had reported cases of the bird flu. As of yesterday, a total of 11 states have reported positive cases.”

It’s hardly Ebola, but H5N1 is the most highly pathogenic strain of bird flu and has reached throughout Asia, Europe, the Middle East and Africa. It is one strain out of dozens of bird flu types, five of which have shown to be a threat to humans: H5N1, H7N3, H7N7, H7N9 and H9N2.

Nigeria recorded in 2007 the first human death from the H5N1 strain, which lives in poultry and is transmittable to humans. It predominately strikes rural areas where standards for handling meat and monitoring of livestock are lower.

The H5N8 strain was detected in a California turkey farm on Jan. 26, just weeks after China banned U.S. poultry in response to an outbreak of two separate virus strains of bird flu in Whatcom County, Washington, the USDA said. No fatalities or human infections have been reported in the U.S. or Canada in 2015.
