Case Count Update
----
Since the last update on 19 Nov 2015, 50 more ill people have been
reported from 16 states. Illnesses that occurred after 21 Dec 2015
might not be reported yet. A series of events occurs between the time
a person is infected and the time public health officials can
determine that the person is part of an outbreak. This means that
there will be a delay between when a person gets sick and confirmation
that he or she is part of an outbreak. This takes an average of 2 to 4
weeks.
As of 21 Jan 2016, 888 people infected with the outbreak strains of
_Salmonella [enterica_ serotype] Poona have been reported from 39
states. The number of ill people reported from each state is as
follows: Alabama (1), Alaska (19), Arizona (134), Arkansas (13),
California (241), Colorado (21), Connecticut (1), Florida (1), Hawaii
(1), Idaho (26), Illinois (11), Indiana (5), Iowa (7), Kansas (2),
Kentucky (1), Louisiana (5), Maryland (1), Minnesota (43), Missouri
(15), Montana (16), Nebraska (8), Nevada (17), New Hampshire (1), New
Mexico (35), New York (6), North Dakota (8), Ohio (3), Oklahoma (13),
Oregon (23), Pennsylvania (2), South Carolina (10), South Dakota (3),
Tennessee (1), Texas (52), Utah (62), Virginia (1), Washington (26),
Wisconsin (46), and Wyoming (7).
Among people for whom information is available, illnesses started on
dates ranging from 3 Jul 2015 to 6 Jan 2016. Ill people range in age
from less than 1 year to 99, with a median age of 18. 49 percent of
ill people are children younger than 18 years. 56 percent of ill
people are female. Among 686 people with available information, 191
(28 percent) report being hospitalized. 6 deaths have been reported
from Arizona (1), California (3), Oklahoma (1), and Texas (1).
According to the California Department of Public Health, Salmonella
infection was not considered to be a contributing factor in 2 of the 3
deaths in California.
Investigation Update
----
Whole genome sequencing (WGS) of _S._ Poona isolates from ill people
and from contaminated cucumbers distributed by Andrew & Williamson
Fresh Produce showed that the strains are closely related genetically.
These results also included isolates from people who became ill in
October and November 2015.
The number of reported illnesses has declined substantially since the
peak of illnesses in August and September 2015; however, it has not
returned to the number of reported illnesses that we would expect to
see (about 1 every month during this time of year).
106 illnesses started after 24 Sep 2015, when recalled cucumbers
should have no longer been available in stores or restaurants. If any
of the recalled cucumbers were still available, they would have
spoiled by that time. State and local public health officials have
interviewed 38 of these ill people. 24 (63 percent) of them reported
eating cucumbers in the week before their illness started. Interviews
have not identified any additional food items potentially linked with
illness. The investigation into the source of these recent illnesses
is ongoing.
