Suspected case is a certain person who’s suffering acute respiratory tract infection with fever symptom (body temperature 38oC), cough, and or sore throat, and or with snot and as well as one of conditions; - One week latest visited fowl husbandry that is spreading outbreak of Avian Influenza. - Contact with confirmation case of Avian Influenza during spreading periods. - Work in Laboratory Department whose processing specimen of human or animal that’s suspected suffering avian influenza. Probable case is a suspected case with one of conditions; - Evidence of limited laboratories that aim at Influenza virus A (H5N1), for example: HI test that is using H5N1 antigen. - For short time quickly becoming pneumonia / respiratory failure / die. - No others etiology be found. Confirmation case is a suspected or probable case that is supported by one of result the investigated laboratories; - Cultured of influenza virus H5N1 is positive. - PCR influenza (H5) is positive. - Increasing titer of H5 antibody is four time quantity. Clinical Symptoms Clinical symptoms that be found in avian influenza as generally influenza symptoms i.e. fever, sore throat, cough, with snot, muscle pain, headache, fatigue. In short time this disease can become more severe as lung infection (pneumonia), and if the treatment of case is bad can cause the patient will die. Etiology and Characteristics Etiology of this disease is Influenza virus. The characteristics of this virus i.e.: able to live endure in water until four days at temperature 22oC and more than 30 days at temperature 0oC. In feces and body of avian or fowl that is ill this virus can live endure more long time, but will die on heating 60oC for 30 minutes. Incubation period Incubation period of influenza virus is variously between 1 – 3 days. Sources and spreading style Spreading of avian influenza (H5N1) in fowl occur accordance with fast by high fatality rate. Spreading this disease occur in the meanwhile fowl population one fowl husbandry, moreover can spread from one fowl husbandry to other area fowl husbandry. Whereas the spreading this disease to human can pass through air which be contaminated by virus from feces or mucus of fowl that is attacked by avian influenza. People who have high risk be attacked by this avian influenza (H5N1) are employee of fowl husbandry, seller and a person who has task fowl preparation. No evidence yet occurs spreading from person to person. Besides that no evidence yet spreading in human passes through fowl meat consumption. Treatments The patient who’s suffering an avian influenza should be treated by hospitalization. In hospital they are given as below: patient 1- Oxygenation, if be found respiratory disorder and it will become respiratory failure in trend by oxygen maintenance more than 90%. - Hydrations by give them intra vena fluids. - They can be given anti viral medicine i.e. : Oseltamivir 75 mg twice every day for 7 days. - In respiratory distress case the treatment is given accordance with RDS procedures and the patient be treated in ICU room especially. - Amantadine/Rimantadin is given in early infection at the first of 48 hours for 3 – 5 days by 5 mg/kg body weigh/day be divided two doses. If the body weighs of patient more than 45 kg is given 100 mg dose twice a day. In elder and patient with decrease of liver or kidney functions the dose must be decreased. patient 2 - Oseltamivir for children less than 15 kg body weigh is 30 mg dose twice a day, more than 15 – 23 kg body weigh is 45 mg dose twice a day, more than 23 – 40 kg body weigh is 60 mg dose twice a day, and more than 40 kg body weigh is 75 mg dose twice a day. Dose of oseltamivir for a patient age more than 13 years is 75 mg twice a day. Prevention efforts Prevention efforts spreading of avian influenza can be done by avoids material that is contaminated by feces and mucus of fowl with efforts as below: - A person who’s contact with material from gastrointestinal tract of bird has to use body protection (masker, goggles). - The material from gastrointestinal tract of fowl as feces must be managed finely (be graved, be burned) in other it does not become spreading sources for people it’s around. - The instrument which be used in fowl husbandry must be disinfected. - Stable and feces may not be exited from fowl husbandry location. - To consumptive chicken meat that is cooked at temperature 80oC for one minute, whereas the fowl egg need be heated at temperature 64oC for five minute. - Keep the environment always clean. - Keep self hygiene.
