FYI..7 People With Swine Flu, US | Arthritis Information
The total number of confirmed cases in recent months of swine flu in the US now comes to 7, with the addition earlier this month of two infected children living in adjacent counties in southern California. None of the infected people had been in contact with pigs, said the Centers for Disease Control and Prevention (CDC).
The latest status report from the CDC, as of 3 pm EST yesterday, shows that 5 of the lab confirmed cases of swine influenza A (H1N1) virus infection are from California (in San Diego County and Imperial County) and the other 2 are from Texas (both in San Antonio). All patients have now recovered.
In the case of the two children, tests revealed they had become infected with viruses that were related genetically but contained a "unique combination of gene segments that previously has not been reported among swine or human influenza viruses in the United States or elsewhere", said the CDC in their April 21 Morbidity and Mortality Weekly Report (MMWR).
The two strains were also resistant to amantadine and rimantadine, the usual treatment for swine flu.
Swine influenza (swine flu) is a disease that regularly affects pigs. It is caused by a type A influenza virus that does not normally infect humans, although we can catch it, mostly from being near infected pigs, although it is possible for it to spread from human to human.
16 dead in flu outbreak; Mexico closes schools, studies strain for link to new US flu
MARK STEVENSON |Associated Press Writer- 11:20 AM CDT, April 24, 2009
MEXICO
CITY (AP) — Mexico City closed schools across the metropolis of 20
million Friday after at least 16 people died and more than 900 others
fall ill from what health officials suspect is a new strain of swine
flu. World health officials worried that it could mark the start of a
flu pandemic.
The World Health Organization in Geneva,
Switzerland said at least 57 have died in the outbreak, although it
wasn't yet clear if this larger number of deaths was due to swine flu.
"We are very, very concerned," said Thomas Abraham, a spokesman for the
agency. "We have what appears to be a novel virus and it has spread
from human to human." If international spread is confirmed, that meets
WHO's criteria for raising the pandemic alert level, he added.
Abraham said WHO on Friday raised their internal alert system, allowing
them to divert more money and personnel to dealing with the outbreak.
"It's all hands on deck at the moment." Abraham said.

Mexico's Health Secretary, Jose Cordova, said only 16 of the deaths
have been confirmed to have been caused by the new strain, through
testing at the government's laboratories. Samples from 44 other people
who died were still being tested. The health department put the total
number of people sickened at around 943 nationwide.
Cordova said samples were sent to
the U.S. Centers for Disease Control and Prevention in
Atlanta,
Georgia, to determine whether it's the same virus infecting seven people in
Texas and
California. As of now, tests show the flu is a "new, different strain ... that originally came from pigs."
"We certainly have 60 deaths that we can't be sure are from the same
virus, but it is probable," Cordova told MVS radio in Mexico City.
Cordova described a chilling new strain that had killed only people
among the normally less-vulnerable young and mid-adult age range. One
possibility is that the most vulnerable segments of the population —
infants and the aged — had been vaccinated against other strains, and
that those vaccines may be providing some protection.
But Dr. Anne Schuchat of the
CDC
said "at this point, we do not have any confirmations of swine
influenza in Mexico" of the kind that sickened seven California and
Texas residents.
All seven U.S. victims recovered from a strain
of the flu that combines pig, bird and human viruses in a way that
researchers have not seen before.
Cordova also told MVS radio
in Mexico City that Mexican health officials can't be sure that the
deaths "are from the same virus, but it is probable."
Closing
the schools kept 6.1 million students home from day care centers
through high schools, and thousands more were affected as colleges and
universities closed down. Parents scrambled to juggle work and family
concerns due to what local media said was the first citywide schools
closure since Mexico City's devastating 1985 earthquake.
Lillian Molina and other teachers at the Montessori's World preschool
scrubbed down their empty classrooms with Clorox, soap and Lysol on
Friday between fielding calls from worried parents. While the school
has had no known cases among its students, Molina supported the
government's decision to shutter classes, especially in preschools.
"It's great they are taking precautions," she said. "I think it's a really good idea."
Authorities advised capital residents not to go to work if they felt
ill, and to wear surgical masks if they had to move through crowds. A
wider shutdown — perhaps including shutting down government offices —
was being considered.
"It is very likely that classes will be
suspended for several days," Cordova said. "We will have to evaluate,
and let's hope this doesn't happen, the need to restrict activity at
workplaces."
Still, U.S. health officials said it's not yet a
reason for alarm in the United States. The five in California and two
in Texas have all recovered, and testing indicates some common
antiviral medications seem to work against the virus.
Schuchat
of the CDC said officials believe the new strain can spread
human-to-human, which is unusual for a swine flu virus. The CDC is
checking people who have been in contact with the seven confirmed U.S.
cases, who all became ill between late March and mid-April.
The
U.S. cases are a growing medical mystery because it's unclear how they
caught the virus. The CDC said none of the seven people were in contact
with pigs, which is how people usually catch swine flu. And only a few
were in contact with each other.
CDC officials described the
virus as having a unique combination of gene segments not seen in
people or pigs before. The bug contains human virus, avian virus from
North America and pig viruses from North America, Europe and Asia.
Health officials have seen mixes of bird, pig and human virus before,
but never such an intercontinental combination with more than one pig
virus in the mix.
Scientists keep a close eye on flu viruses
that emerge from pigs. The animals are considered particularly
susceptible to both avian and human viruses and a likely place where
the kind of genetic reassortment can take place that might lead to a
new form of pandemic flu, said Dr. John Treanor, an infectious disease
specialist at the University of
Rochester Medical Center.
The virus may be something completely new, or it may have been around
for a while but was only detected now because of improved lab testing
and disease surveillance, CDC officials said.
The virus was first detected in two children in southern California — a 10-year-old boy in
San Diego County and a 9-year-old girl in neighboring Imperial County.
It's not known if anyone is getting sick from the virus right now, CDC officials said.
It's also not known if the seasonal flu vaccine that Americans got last
fall and early this year protects against this type of virus. People
should wash their hands and take other customary precautions, CDC
officials said.

get your vaccines!! This is some bad stuffIt was announced on the news here last night that cases had now been identified in Texas.
I wonder if I could get another flu shot? Tami-flu?
I just heard an update, the cases were in my neck of the woods, about 50miles from here (close enough!). Scary! A shot is not available and, as of now, they are really not looking into developing one until they see where it is headed. They did say Tamiflu was working pretty well.
Health chief: Swine flu has 'pandemic potential'
Never-before-seen mixture of swine, human and avian viruses kills up to 68
