Backgrounds: On 23^rd May 2016, Sa Kaeo Crown Prince Hospital had reported to the Epidemiology Unit of Sa kaeo Public Health Office, that they found a patient dead by Streptococcus suis sepsis. The Sa Kaeo provincial and district SRRT teams went to investigate the cause of infection in the following days.
Methodology: Reviewed the medical record about signs and symptoms for data collection and scoping the investigation. Then identified other persons who dissected and/ or consumed the dead pork meat in the community by interview her relatives. Reviewed the Sa Kaeo Public Health epidemiological surveillance of Streptococcus suis in 2014-2016 to find more details about history of occurrence and distribution. The investigation team interviewed such as animal carcass dissection, trading, or consuming pork weak from suspicious farms, to identify the disease agents. Then the information was analyzed and interpreted the result on the disease occurrence and its distribution based on time, place, and person. After that, we had regulated a defensive measurement to prevent further infection or outbreak.
Result: 66 year-old female death lived in moo 2, Nhongkok village Salalumduan sub-district, Muang district Sa kaeo Province. Her underlying diseases were high blood pressure, dyslipidemia and history of chronic alcohol drinking for 40 years. She had dissected a suspicious dead pig from a closed farm in that area, 7 days before she got sick. The onset of illness was found on 8th May 2016, and she died on 22th May 2016. From a laboratory tested that she was infected with Streptococcus suis.
Conclusions: The dead patient might be infected from the dead pig. The infection could be cause from dissecting the pig carcass without proper protective equipment, and another promoting cause could be from her underlying disease and chronic alcoholism.
