China Battles First Outbreak of Deadly African Foot-and-Mouth Disease
Listen to the full version
China is scrambling to contain its first domestic outbreak of a highly lethal African strain of foot-and-mouth disease, fast-tracking emergency vaccines as the agricultural sector faces a widening threat to its livestock industry.
The South African Type 1, or SAT1, strain has been officially confirmed in the western regions of Xinjiang and Gansu. Existing national vaccines, which primarily target the traditional O and A serotypes, fail to provide cross-immunity against the new strain. Cattle, sheep and pigs are all susceptible, with the mortality rate for young cattle reaching up to 50%.

- China reports first SAT1 foot-and-mouth outbreak in Xinjiang (142/513 cattle infected in Yining), Gansu (77/5,716 in Gulang), and Shanxi; 50% mortality in young cattle.
- SAT1 strain from Africa evades O/A vaccines, spreads rapidly with 100% morbidity, slow/concealed symptoms.
- Response includes culling, transport bans, market halts; emergency SAT1 vaccines approved for Zhongnong Weite and Jinyu until June 2026.
1. China is urgently addressing its first outbreak of the highly lethal South African Type 1 (SAT1) strain of foot-and-mouth disease (FMD) in Xinjiang and Gansu, fast-tracking emergency vaccines amid threats to livestock [para. 1][para. 2].
2. SAT1, confirmed by the national reference lab, evades existing O and A serotype vaccines; it affects cattle, sheep, and pigs, with up to 50% mortality in young cattle [para. 2][para. 3].
3. Outbreaks reported March 28: Yining (Xinjiang) trading market had 513 cattle, 142 infected; Gulang (Gansu) farm had 5,716 cattle, 77 infected; measures include culling and monitoring [para. 3][para. 4].
4. April 7 confirmation in Inner Mongolia specified SAT1 "broke through the border" [para. 5].
5. SAT1 typically Sub-Saharan African; South Africa's Ramaphosa declared national disaster in February 2026 due to SAT1/2/3 spread [para. 6].
6. UN FAO March 4 update: SAT1 in Iraq (March 2025), then Kuwait/Turkey/Iran; risks to Russia/Afghanistan/Pakistan [para. 7].
7. Vet Xu Lang in Gansu/Ningxia noted government alert late March, found infections early April; SAT1 symptoms slower than O/A types [para. 8][para. 9].
8. SAT1 more concealed, spreads undetected for days, harder to control; adult cattle lower mortality, calves up to 50%; spreads via contact/airborne/objects; Xu now advises online [para. 10][para. 11].
9. Nationwide prevention ramps up; April 8 notices in Fujian/Guangxi/Hunan cite Wenshui (Shanxi) outbreak, calling situation "extremely severe" [para. 12][para. 13].
10. SAT1: ~100% morbidity, >50% young livestock mortality (vs. 10-20% common FMD), 14-day incubation, O-type-like symptoms, sheep asymptomatics; piglets die from myocarditis [para. 14].
11. Wenshui halts cattle/sheep transport; Ningxia/Inner Mongolia suspend trading; Hebei's Zhangbei market bans Gansu/Inner Mongolia cattle, volume halves (from 10,000 to 5,000 head), broker Zhang notes drop from 10 to 5 head/day [para. 15][para. 16][para. 17].
12. Emergency approvals: Zhongnong Weite's SAT1 subunit and inactivated vaccines until June 30, 2026 [para. 18].
13. Shandong farmer Gao vaccinated free April 7 with fresh subunit vaccine, no reactions; Ningxia/Gansu/Guizhou farmers report free shots [para. 19][para. 20][para. 21].
14. Jinyu Bio-technology subsidiary approved for two SAT1 vaccines April 8 [para. 22].
15. Spring peak trading risky; 21-day vaccine immunity gap; advise closed management, disinfection; carriers up to 2 years in cattle [para. 23].
