The affected population is within a communal farming area. Cattle initially presented with lameness followed by salivation. Mouth and foot lesions from erosions to ulcers of varying severity were noted. Oral lesions were predominantly ulcers/erosions on the tongue and dental pad and gums, under-run dorsal tongue epithelia with halitosis in severe cases. Foot lesions included interdigital ulcers and coronary separation especially the distal part of the hoof. One case had teat lesions. Only cattle are showing clinical signs. The estimated population at risk is about 90,000 cattle in the entire zone 7.
Diagnosis:

- virus neutralisation
- virus isolation
pending Source of outbreak or origin of infection: unknown or inconclusive.
Control measures undertaken:
- quarantine;
- movement control inside the country;
- screening;
- zoning;
- disinfection of infected premises/establishment(s);
- dipping/spraying.
Treatment of affected animals: no.

Other details/comments:
The Selibe Phikwe district (zone 7) shares the international boundary to the north and north-east with Zimbabwe and Northern Tuli/Mashatu Game Reserve, with South Africa to the south-east and with Zones 9, 8 and 6 in the southern, western and northern areas, respectively. These zones are separated by cordon fences including along the international boundary.
The following measures have also been put in place:
- self-imposed ban on exports of cloven-hoofed animals and their fresh products;
