Peste des petits ruminants (PPR) is a highly contagious and deadly disease in small ruminants that have gained focus from both the Food and Agricultural Organization of the United Nations (FAO) and the World Organization for Animal Health (OIE) as one of the most important animal diseases present today. The FAO and OIE have joined in an effort to control and eradicate PPR as a step to secure livelihood and fight poverty, as many of the most vulnerable groups rely on their sheep and goats for food and income. PPR is caused by the peste-des-petits-ruminants virus (PPRV). Since it was discovered in 1942 in Côte d'Ivoire it has spread from eastern Africa to almost all of Africa and Asia. This area holds the major part of the worlds sheep and goat population, with 1.7 billion animals at risk.
In December 2019 I defended my thesis “Peste-des-petits-ruminants virus–in the host and in the field”. The focus of the thesis was on the epidemiology and diagnostics methods, as well as the virus-host interactions of the PPRV. I am now continuing my work with PPR as well as studying other morbilliviruses such as the recently discovered feline morbillivirus.
Before becoming a part of the section of virology I studied at SLU and I have a master’s degree in veterinary science. I did my master’s degree project on molecular epidemiology of rabies at University of Sao Paulo, Brazil. After graduating in 2013 I worked as a small animal veterinarian at the University Animal Hospital (UDS) and also as a teacher for veterinary students at SLU.
