How It Is Spread
The virus can be carried and spread by intermediate hosts and also by direct contact with the infectious wounds. Birds in overcrowded conditions have an increased risk of injury, and may result in fighting and pecking. The virus cannot enter intact skin but can survive for a long time in infected material, such as scabs and litter.
The virus can remain in the environment for months, particularly in dry and shaded areas.
Many Pox Outbreaks Are A Result Of Improperly Administered Vaccine
Live pox virus vaccines should be used within one hour of preparation and should not be exposed to conditions that could inactivate the virus. It is important to evaluate pox vaccination crews and correct application problems.
Crew assessment sheets should include flock identification, cage row number/level, vaccinators name, and both start/finish date and times. The quantity of vaccine used per flock should also be checked and recorded.
In flocks that receive multiple pox vaccinations or one at a day of age, the percentage of “takes” or degree of vaccine reaction from subsequent vaccinations will be lower than 99100 per cent, due to protection from an earlier vaccination.
“Takes” should still be checked and recorded after each vaccination event in order to develop a complete flock history.
Fowl Pox Vaccine Indications
This vaccine is recommended for subcutaneous vaccination of healthy one-day-old chickens. It is essential that the chickens be maintained under good environmental conditions and that exposure to disease viruses be reduced as much as possible.
PREPARATION OF VACCINE
1. Dilute the vaccine only as directed, observing all precautions and warnings for handling.
2. Remove from the liquid nitrogen only the ampules that are going to be used immediately. Move quickly, but carefully.
3. Place the ampule in a large, clean container of water at 68° to 86°F to thaw ampule quickly. Thaw the entire contents. Gently swirl the ampule to disperse contents. Break ampule at its neck and quickly proceed as described below.
4. Use 200 ml of sterile diluent for each 1,000 doses of vaccine to be injected subcutaneously. Remove the cover from the diluent container. Draw contents of the ampule into a sterile 10 ml syringe fitted with an 18 to 20 gauge needle. Slowly add the contents of the vaccine ampule to the appropriate volume of diluent. Withdraw a small amount of the diluent, rinse the ampule once and add this to the vaccine-diluent mixture. Mix the contents of the diluent container thoroughly by swirling and inverting the container. Do not shake vigorously.
5. Keep the container of diluted vaccine in an ice bath. Use the vaccine-diluent mixture immediately. Agitate as needed to ensure a uniform suspension of the cells.

Clinical Signs And Lesions
The disease may occur in either one form , or both forms. Clinical signs can vary, depending on the susceptibility of the host, virulence of the pox virus, distribution of lesions, and/or other complicating factors.
Papules: the initial lesions, light-colored nodules in skin
Vesicles and pustules: raised yellow lesions
Crust : the end-stage lesions, reddish brown-to-black lesions
- Cutaneous eye and mouth lesions interfere with the birds ability to eat and drink
- Birds lack vigor and have loss of appetite and reduced egg production
- Low mortality if uncomplicated disease.
- Cankers or diptheritic yellowish lesions occur on mucous membranes of mouth, esophagus or trachea
- Lesions in the nasal cavity or conjunctiva of eye lead to nasal or ocular discharge
- Reddened tracheas
- Thickened tracheal wall with proliferative and inflamed lesions on the interior surface
- Lesions can interfere with eating, drinking and breathing wet pox involving the trachea can result in high mortality due to impairment of breathing
- Unthriftiness and reduced egg production
- Mortality due to suffocation, starvation and dehydration
- Mild to severe respiratory signs birds typically die due to obstruction of trachea at the glottis
- Respiratory lesions and clinical signs can be very similar to infectious laryngotracheitis .
- Other differentials are viscerotropic velogenic Newcastle disease , avian influenza , Mycoplasma gallisepticum , infectious coryza, and fowl cholera.
Why Is A Vaccine For Chickenpox Needed
Chickenpox is a disease that can be very easily spread from person to person. It is most common in children. Most cases occur in people who are younger than 15 years of age. Chickenpox is usually a mild illness. The most common symptom is itchy red dots that appear over the entire body. The dots turn into fluid-filled blisters and end as scabs. The disease can also cause flu-like symptoms, including fever, drowsiness, poor appetite, headache, and sore throat. Some children get sicker than others.
Chickenpox can be a very serious illness in infants and adults. It can cause problems such as skin infections, brain swelling, and pneumonia. Because chickenpox is so contagious, a child who has chickenpox shouldnt go to school or day care until all the sores have dried or crusted. Many parents miss work during the time their child has chickenpox.

Variant Strains Of Fowl Pox
In some parts of the world, new fowl pox variant strains have emerged due to the integration of various genome segments of reticuloendotheliosis virus into the pox genome. This results in the new virus being more difficult to control with standard fowl pox vaccines.
Affected flocks will typically test positive for REV antibody, but do not have tumours or other signs of REV infection. New vaccines may be developed to better control these pox strains in the future.
Anecdotal evidence suggests that use of a mix of fowl pox plus pigeon pox vaccine may improve protection against these variants.
Directions For Addition Of Blue Dye To Sterile Diluent
Blue dye may be aseptically added to sterile diluent using the following procedures:

A Vaccination Programme Will Increase Profits By Reducing Mortality And Improving The Health Of Chicks
Vaccines must be properly administered to be effective, says Rick van Oort, corporate product manager of poultry at global veterinary health company, Ceva.
Workers should know the standard operating procedure. Catchers, for example, should present birds to vaccinators so that the vaccination site can be clearly seen. Vaccination guns must be calibrated and sterile needles used.
READ Vaccinate your livestock!
VaccinesVaccines that are not properly reconstituted will offer no protection. Live vaccines contain a weakened live form of the disease-causing organism, while inactivated vaccines contain disease-causing organisms that have been killed by heat or some other means.
The following must be given during rearing:
Viral booster vaccines with inactivated vaccinesBacterial vaccinesFowl cholera
Live vaccines offer longer protection than inactivated vaccines.
Vaccines must be kept cool and used within two hours, says Rick. Check the insert or speak to the vet.
Spray vaccinationsWith a coarse spray, its important to use the correct amount of unchlorinated water, says Rick. For day-old chicks, use 150m to 200m per 1 000 birds.
During the first three weeks, increase the water to between 200m and 500m per 1 000 birds. After that, use 1 000m for the same number of birds.
Fine-spray vaccinations penetrate the trachea and lungs, resulting in a better reaction.
Is it working?
This can be done by checking 10% of the flock, or a set number of birds per vaccinator.

Fowl Pox In Layers: An Overview
Fowl pox is a common and economically important disease of layers, causing drops in egg production and increased mortality. Alice Mitchell
The disease is a slow-spreading one, characterised by the development of skin lesions on the unfeathered skin of the head, neck, legs and feet .
The diptheritic lesions are associated with the upper digestive and respiratory tracts, especially the larynx and trachea. Wet pox is the more serious form of the disease, with higher mortality in flocks.
Wet pox alone can cause high mortality of up to 5060 per cent in unvaccinated flocks. In layers, the disease causes a drop in egg production and reduces growth and development in young chicks and pullets.
Diagnostic Guidance: Fowl Pox
Diagnostic Guidance: Fowl PoxBy Martin Ficken, DVM, PhD
Fowl pox is caused by a DNA virus . Many species of birds have their own specific pox virus.
Infection can occur in two different forms: dry and wet. Dry pox occurs through mechanical transmission of the virus to injured or lacerated skin and can occur at any age. Biting insects, such as mosquitos, serve as mechanical vectors often resulting in ocular infection. Wet pox causes diphtheritic lesions and often has a higher mortality rate. The lacrimal duct is a frequent transmission route, as the virus can reach the laryngeal region after entry.
Dry pox ranges from mild to severe depending on infection rate. The characteristic lesion of the cutaneous form is epithelial hyperplasia involving the epidermis and underlying feather follicles, with formation of nodules that first appear as small white foci that often rapidly increase in size and become dark in color . Adjoining lesions may coalesce and become rough and induce secondary infections or interfere with vision or breathing .
Wet pox occurs as elevated white opaque nodules or yellowish patches on the mucous membranes of the mouth , esophagus, tongue, glottis, or upper trachea . Nodules rapidly increase in size and often coalesce to become a yellow cheesy, necrotic, or diphtheritic membrane.

What Causes Fowl Pox
Fowl pox is caused by an avian DNA pox virus. There are five or six closely related viruses that primarily affect different species of birds but there is some cross-infection. Infection occurs through skin abrasions or bites, through the respiratory route and possibly through ingestion of infective scabs. It can be transmitted by birds, mosquitoes or fomites . The virus is highly resistant in dried scabs and under certain conditions may survive for months. Mosquitoes can harbour infective virus for a month or more after feeding on affected birds and can subsequently infect other birds. Recovered birds do not remain carriers. A flock may be affected for several months as fowl pox spreads slowly.
Fowl Pox Vaccine Caution
Do not spill or splatter the vaccine. Burn containers, unused vaccine and accessories prior to disposal. Do not over dilute the vaccine or otherwise extend the dosage. Store unopened vaccine vials at not over 45° F or 7° C. Do not vaccinate within 21 days of slaughter or 4 weeks prior to start of lay. The vaccinated chickens should not be placed on contaminated premises. All susceptible chickens on the same premises should be vaccinated at the same time. If this is not possible, then strict isolation and separate caretakers should be employed for non-vaccinated chickens. Efforts should be made to reduce stress conditions at the time of vaccine administration.
The vaccine is supplied in 10 x 1000 dose vials with diluent, product insert and wing web applicators.
Rehydrate with 10 ml of diluent. For wing web administration in chickens. For veterinary use only.

Path To Improved Health
Chickenpox was once a common childhood disease until a vaccine was invented to prevent it. Today, you can keep your children from getting chickenpox by making sure they get the vaccine.
The purpose of a vaccine is to prevent you from getting a specific disease. The chickenpox vaccine is called the varicella vaccine. It is called varicella because the varicella virus causes chickenpox. Up to 90% of people who receive the vaccine will not get chickenpox. People who get chickenpox after having the vaccine have a milder form of the disease.
Use Of Vaccine For Subcutaneous Injection
IMPORTANT: Sterilize vaccinating equipment by autoclaving a minimum of 15 minutes at 250°F or boiling in water for at least 20 minutes. Never allow chemical disinfectants to come in contact with vaccinating equipment.
1. Use a sterile automatic syringe with a 20 to 22 gauge 3/8 to 1/2 needle that is set to accurately deliver 0.2 ml per dose. Check the accuracy of delivery several times during the vaccination procedure.
2. Inject chickens under the loose skin at the back of the neck , holding the chicken by the back of the neck just below the head. The loose skin in this area is raised by gently pinching with the thumb and forefinger. Insert the needle beneath the skin in a direction away from the head. Inject 0.2 ml per chicken. Avoid hitting the muscles and bones in the neck.
3. Use the entire contents of the vaccine container within one hour after mixing the vaccine with the diluent.

Prevention And Treatment Of Fowl Pox
There is no treatment for fowl pox and prevention is through vaccination of replacement birds. Where preventative vaccination is used, all replacement chickens are vaccinated when the birds are six to ten weeks of age and one application of fowl pox vaccine results in permanent immunity. Vaccination of broilers is not usually required unless the mosquito population is high or infections have occurred previously. Chicks may be vaccinated as young as one day of age. During outbreaks, unaffected flocks and individuals may be vaccinated to help limit the spread. If there is evidence of secondary bacterial infection, broad-spectrum antibiotics may help reduce morbidity and mortalities. As mosquitoes are known reservoirs, mosquito control procedures may be of some benefit in limiting spread in poultry confined in houses.
