Scientific Name: 
African swine fever virus (Alonso et al. 2018)
Common Name: 
African swine fever
Native To: 
First identified in Kenya in 1921 (Sánchez‐Vizcaíno et al. 2012)
Date of U.S. Introduction: 
Has not been detected in the U.S. (Brown and Bevin 2018)
Means of Introduction: 
Most likely pathway into the U.S. is the illegal importation of swine products or byproducts (APHIS)
Highly contagious and fatal viral disease affecting domestic and wild pigs; one of the most economically devastating diseases of swine (APHIS; Sánchez‐Vizcaíno et al. 2012)


USDA. Animal and Plant Health Inspection Service.

The U.S. Department of Agriculture's (USDA) Animal and Plant Health Inspection Service (APHIS) and the Canadian Food Inspection Agency (CFIA) have developed a protocol to help ensure bilateral trade will continue if African swine fever (ASF) is detected in feral swine in either country, while still absent from domestic swine. The intent of the protocol is to protect swine populations in both countries during an outbreak of ASF in feral swine, while minimizing impacts on the trade of live swine, swine products, and other swine commodities.

ARS scientists at the Plum Island Animal Disease Center in Orient Point, NY, have made two important advancements against African swine fever virus, which causes a lethal disease in pigs.

Feral swine can carry foreign animal diseases like African Swine Fever. While ASF has never been found in domestic or feral swine in the United States, there is no treatment or vaccine for it. That’s why surveillance is very important. Help protect U.S. pigs by immediately reporting sick or dead feral swine.

WHAT TO DO: If you find a sick or dead feral swine with no obvious injury or cause of death, report it right away. Call the USDA-APHIS Wildlife Services program in your State at 1-866-4-USDA-WS. Don’t wait! Quick detection is essential to preventing the spread of ASF.

World Organisation for Animal Health; UN. Food and Agriculture Organization.

The escalation of the spread of African swine fever (ASF) has placed most of the world's domestic and wild pig populations under direct threat. To support countries' efforts to protect economies and food security, the World Organisation for Animal Health (OIE) and the Food and Agriculture Organization of the United Nations (FAO) have launched a joint initiative for the Global Control of ASF (PDF | 5.7 MB).

United States Department of Agriculture.
Today, since prevention is our best protection against African swine fever, U.S. Secretary of Agriculture Sonny Perdue is sharing information about the importance of keeping ASF out of the United States. It is vital for everyone to know about ASF and how to prevent it, while keeping the U.S. pig population healthy. To help people learn more about this disease, as well as the steps that can be taken to help protect U.S. pigs, the USDA's Animal and Plant Health Inspection Service has updated its web content with additional information and links to partners’ resources.

Additionally, USDA is releasing four infographics on the following topics:
