2011
In June 2011, a report was received about four puppies
that tested positive for Canine Influenza by PCR in the
South Bay Area. The puppies originally were turned in to
a local animal shelter, where they were vaccinated
against canine influenza (killed virus), in addition to
Distemper, Hepatitis, Leptospirosis, Parainfluenza,
Parvovirus (DHLPP) and Bordetella. They were
emaciated and tested positive for Demodex
mange. The puppies were then taken by a rescue group and
treated at a local veterinary hospital. They had slight
fevers when first examined, and developed a slight cough
a week after entering the hospital. PCR testing for
canine influenza was performed on pharyngeal and
conjunctival swabs collected on the first day of
coughing. Their illness was mild and recovery was seen
within days. It remains unclear where the four puppies
contracted the infection. There was no indication of a
larger outbreak at the clinic.
2007
In July
2007, a veterinary clinic in the San Gabriel Valley reported a
cluster of respiratory disease associated with the dog
boarding section of their facility. A total of
approximately 40 dogs became ill over a period of 3
weeks. Exposure to canine influenza was confirmed
by serologic testing in 5 of the cases. Vigorous infection control measures
were implemented to control the outbreak. Most of the
dogs had mild symptoms, although four dogs developed
pneumonia. This outbreak appeared to be triggered
after a puppy from Colorado, sick with pneumonia, was
brought into the clinic. The canine influenza vaccine
was not available in 2007, so none of the dogs had been
vaccinated.
2005
In September
2005, an Inglewood veterinarian confirmed four cases among dogs that had been at a single boarding facility at various times during August
of that year. Veterinary Public Health conducted extensive surveillance
for 6 months following that outbreak, but did not detect
additional cases.
