Publisher: 2014Dissertation note: Animal bites people should be considered an important public health problem. Moreover, the number of pets, specifically the dog, is increasing. (Palacio J et al., 2003).Animal bites, particularly dog bites, are a major public health problem throughout the world (Morgan and Palmer, 2007). Animal bites and scratches, even when they are minor, can become infected and spread bacteria to other parts of the body.
Dog attacks, by street or domestic dogs, with injuries from very minor to significant and severe to fatal, are not uncommon. According to WHO report, ten million people are bitten by animals (especially Dogs) around the world, considered for prophylaxis and treatment against rabies and almost (55,000) people die from this disease annually (Mohdjunaid et al., Oct 2012).
6.2 Hypothesis:
The incidence of dog bite injuries is high in densely populated towns of Lahore when compared to less populated towns of Lahore.
6.3 Methodology:
General information about patients and possible causes was collected on a structured questionnaire. All the dog bite victims that were come to emergency ward during three months period were included in the study. Questionnaire include closed questions about the demographics of the victims, circumstances of bite incidents, body parts injured and the degree of injury, type of dog, history of previous bites, the level of knowledge about rabies, post bite home treatment (washing of bite wound etc.) prior to visited the hospital for medical treatment and post exposure treatment at hospital. The densely populated area (ravi town, data ganj bakhsh, shalimar town, samanabad etc) and less populated area (gulberg, azizbhati town, wagah, Allama iqbal town, & nishtar) was be compared.
6.4 Statistical Design
Cumulative incidence was calculated as described by Leon Gordis (2008). Chi square test was applied on the data by using SPSS (version 19.0).
6.5 Results
In this study, cumulative incidence is 4.653 per 1000 popluation, most of the dog bite victims were male 79.9 % as compare to female 20%.5.7% cases visited Mayo Hospital’s emergency department during the study period, 4.5% cases were reported in Services Hospital and 89.9% cases from IPH Lahore. In this the higher percentage was the patients who were illiterate (47%) and very few patients were those who had intermediate and above education (6%). The occupation of the patients who were attended Hospitals, were farmers (31.56%). The 24% patients were those who had bitten once before in previous years. In those 24% patients 19.2 % those who were bitten by dog and 5% were bitten by others (cats, horse, donkeys, etc). Most of the victims were bitten in rural area (65%) and most of the injuries were from stray dogs (65.9%). Most of the victims had provoked bite (74%) and the high frequency were recorded that the cases had type II wound category (deep scratch but no bleeding) 82%. The cases received treatment in different hospitals were RIG (18%), Tetanus toxoid (32%), Antibiotic (78%) and Suturing (7.9%).
Most of the patients were from Ravi town Lahore that is one of the highly densely populated areas of Lahore (38%) and very few cases reported from Nishtar town Lahore (0.5%). The demographic location and the hospitals had no association as the results were insignificant (p-value>0.05). Most of the cases who were bitten by dog and they already bitten by dog in previous years, significant in relation as p-value <0.05. The association between dog status and biting animal was significant, as mostly biting dogs were stray dogs and most of the bite was provoked, there was significant association between biting animal and biting type (p-value<0.05).

Publisher: 2016Dissertation note: Avian Influenza is the most feared disease of poultry and other birds throughout the world. The segmented, negative strand RNA viruses that form the family Orthomyxoviridae are divided into three types of influenza virus, A, B and C. Only influenza A viruses have been reported to cause natural infections of birds. The outbreak can be mitigated by applying biosecurity measures, controlling poultry movement, using inactivated vaccines and initiating an AI surveillance network throughout the country.
A targeted survey was conducted for a period of 3 months in order to determine prevalence of Avian Influenza H5, H7 and H9 in the villages of Kasur district. Two stage cluster sampling without replacement was adopted in this study. Thirty clusters were selected and in each cluster, seven elementary units (chicken) were sampled, i.e. a total of 210 birds. Tracheal swabs were collected from live and apparently healthy backyard birds then swabs were stored properly at 4°C (24-48hours) until processed. Data were collected from the owner in a face to face interview. A detail predesigned questionnaire was filled after taking written consent from the owner. The sample was collected during the survey of backyard poultry in villages of Kasur district was processed for laboratory analysis. Polymerase chain reaction for Avian Influenza virus isolation was conducted to diagnose sample for AIV.
The weighted proportion estimate with 95% Cl (confidence intervals) of the overall prevalence was computed by using “R” software. Multivariable logistic regression was conducted to estimate the effect of each study variable on the outcome. Variables with significant univariate relationship at p <0.25 was selected for inclusion in the final model. Odds ratios (ORs) and corresponding 95% Cl (confidence intervals) were calculated (Hosmer and Lemeshow, 2000).

SUMMARY
Discussion

The management practice risk scores provide a means to quantify the level of risk to avian influenza across villages. However, the utility of such a measure cannot be assessed until these are related to AI status form clinical tests. Nevertheless it is useful to assess what factors are associated with these scores. In particular, specific profiles of farms can be identified with potential high risk and control resources allocate accordingly. For example, this study has found amongst other things that farms with mixed poultry breeds, which have reported diarrhea, or reported high mortality have high risk scores, and these might be targeted for intervention. Prevalence estimate of Avian Influenza was generated. Potential risk factors associated with this prevalence was identified and will be communicated to concerned persons through publication. The poultry birds reared completely outdoor have more chance to contact with wild birds which increase the occurrence of AIV. A strong association between source of water and AIV was found. Water source can play a vital role in transmission of AIV. Another strong association was found in unethical disposal of dead birds and waste poultry farm near to houses with increase the chances of infection. Presence of live bird market stall and visiting of poultry farm vehicle to villages can increase the chances of AIV infection. Elimination or reduction of above mentioned risk factors, use of disinfectant for cleaning and regular vaccination against AI could significantly improve backyard poultry production system in villages.
