INTRODUCTION

The Parvo viral infection in canine population was first recognized in 1978 that caused Parvovirus enteritis or myocarditis in U.S.A. After that, this was observed in Canada, Australia and England. And in following year in France, Holland, Belgium, Switzerland, Sweden, West German and other countries (Anon, 1979; Mc Candlish et al .,1979).

The canine parvovirus (CPV) infection is a highly contagious viral illness that affects dogs.

Susceptible Hosts

Wide varieties of hosts are affected with parvo virus infection. They are cattle, pig, dog, cat, man, rat, mice, chicken, and hamsters. Breeds like Doberman, English Springers, Labrador are at risk.

Mean age and range: Most severe illness may occur in pups 6-16 weeks of age.

Mode of transmission

The virus is transmitted through direct or indirect contact with the infected animal or its excretions. Viruses are excreted in large quantity through the excreta of the hosts.

Virus excretion continues for 12-14 days from infected animal (Pollock, 1981).

Clinical signs

Slight to high rise of temperature (Initial stage)

Vomiting

Bloody Diarrhea

Loss of appetite

Treatment of Parvo Virus infection

Symptomatic treatment Anti Vomiting drug Anti diarrhoeal drug

Supportive treatment Fluid therapy

OBJECTIVESGeneral objective

The study on the clinical cases attended by MVCS(Mobile Vet Consultancy Service) from the year 1st Baishakh 2072 to 30th Chaitra 2072 BS (14 April 2015 to 13 April 2016 AD).

Specific objectivesTo find out the overall clinical cases in dogs attended by MVCS.To find out the status of occurrence of clinical case as per age

wise, sex wise and as per season wise .

Justification of study

The studies on the clinical case are very useful to find out the occurrence pattern of the disease, distribution of disease according to various factors like age, sex and time.

Very few studies had been conducted in Nepal to determine the prevalence of parvo virus.

Limitations of study

This study was done only within limited period of time.

Due to this, the analysis had to be completely based on secondary data in Mobile Vet Consultancy Service, Jawalakhel, Lalitpur.

Sampling error may exist.

Conclusion

This study shows overall prevalence of parvo virus infection in canine of Kathmandu valley in Baishakh is higher i.e 95,which is 21%. Because Climate condition is favourable for spread the virus.

Age between (1-2) month is more susceptible as Puppies are born with a very immature immune system and don’t begin making their own antibodies until about 6 weeks of age. (Van Buren Ave, 1929).

Male is more susceptible then female Because client interest to keep male dog then female.

Suggestions

• Owners should be immediately consult veterinarian if their pets get diarrhea and vomition.• Vaccination should be done in schedule.• Regular monitoring should be done for the parvo virus suspected

dogs.• Isolation of parvo infected dog should be done from the kennel.• Disinfect the dog’s environment.• Treating the infected dog.• vaccination all pets that have contact with affected pet.
