According to the latest report by the Guatemalan authorities sent to the OIE on the occurrence of classical swine fever, the Chituplun Chines outbreak was reported to the veterinary authorities by a formulated feed seller. It is limited to this farm. No further cases have been observed. Epidemiological surveillance continues at national level.

As a preventive measure, emergency vaccination of healthy pigs will be implemented on this farm and on backyard pigs in a 3-km-radius zone. Vaccination will be done only by the veterinary authorities and vaccinated animals will be identified with ear tags for further epidemiological monitoring.

Laboratory tests show that some samples reacted to the antigen detection ELISA and were PCR-positive, but did not react to the antibody detection test. Moreover, other samples reacted to the antigen and antibody detection ELISA, but were PCR-positive.

In the field, pigs were apparently healthy and had no clinical signs, but they were positive to laboratory tests.

In post-mortem, some dead animals show lesions consistent with classical swine fever.
This virus has caused low mortality in pigs; it is apparently a low pathogenic virus.
