New type of swine flu hits California and Texas

Posted by feww on April 24, 2009

UPDATE: Mexican govt says new flu virus probably killed 81

Report from CDC Website

Swine Influenza (Flu)

Swine Influenza (swine flu) is a respiratory disease of pigs caused by type A influenza that regularly cause outbreaks of influenza among pigs. Swine flu viruses do not normally infect humans, however, human infections with swine flu do occur, and cases of human-to-human spread of swine flu viruses has been documented. General information about swine flu can be found on the General Information about Swine Flu page.

From December 2005 through February 2009, a total of 12 cases of human infection with swine influenza have been reported from 10 states in the U.S. Beginning in March 2009, a total of 5 laboratory confirmed human cases of swine influenza virus infection have been identified in California. An investigation into the human swine flu cases in California is ongoing. More information is available on the Human Swine Flu Investigation page.

Residents of California and Texas

CDC has identified human cases of swine influenza A (H1N1) virus infection in people in these areas. CDC is working with local and state health agencies to investigate these cases. We have determined that this virus is contagious and is spreading from human to human. However, at this time, we have not determined how easily the virus spreads between people. As with any infectious disease, we are recommending precautionary measures for people residing in these areas.

  • Cover your nose and mouth with a tissue when you cough or sneeze. Throw the tissue in the trash after you use it.
  • Wash your hands often with soap and water, especially after you cough or sneeze. Alcohol-based hands cleaners are also effective.
  • Try to avoid close contact with sick people.
  • If you get sick, CDC recommends that you stay home from work or school and limit contact with others to keep from infecting them.
  • Avoid touching your eyes, nose or mouth. Germs spread that way.

There is no vaccine available at this time, so it is important for people living in these areas to take steps to prevent spreading the virus to others. If people are ill, they should attempt to stay at home and limit contact with others. Healthy residents living in these areas should take everyday preventive actions.

People who live in these areas who develop an illness with fever and respiratory symptoms, such as cough and runny nose, and possibly other symptoms, such as body aches, nausea, or vomiting or diarrhea, should contact their health care provider. Their health care provider will determine whether influenza testing is needed.

Clinicians

Clinicians should consider the possibility of swine influenza virus infections in patients presenting with febrile respiratory illness who:

  1. Live in San Diego County or Imperial County, California or San Antonio, Texas or
  2. Have traveled to San Diego and/or Imperial County, California or San Antonio, Texas or
  3. Have been in contact with ill persons from these areas in the 7 days prior to their illness onset.

If swine flu is suspected, clinicians should obtain a respiratory swab for swine influenza testing and place it in a refrigerator (not a freezer). Once collected, the clinician should contact their state or local health department to facilitate transport and timely diagnosis at a state public health laboratory.

State Public Health Laboratories

Laboratories should send all unsubtypable influenza A specimens as soon as possible to the Viral Surveillance and Diagnostic Branch of the CDC’s Influenza Division for further diagnostic testing.

Public Health /Animal Health Officials

Officials should conduct thorough case and contact investigations to determine the source of the swine influenza virus, extent of community illness and the need for timely control measures.

    Suspected Mexico flu toll hits 81
    Public events have been cancelled and schools closed in Mexico’s capital

    The Mexican authorities say 81 people are now thought to have been killed by an outbreak of a new flu virus.

    Public buildings have been closed, large events cancelled and people told to stay at home in an attempt to prevent the spread of infection.

    The World Health Organization has said the virus could become a pandemic and is a matter of “international concern.”

    Several people have also fallen ill in the United States, but there have been no reported fatalities.

    Hundreds of public events have been suspended in Mexico and schools in and around the capital, Mexico City, have been closed until 6 May.

    Museums and libraries have also been closed and people are being urged to avoid shaking hands or sharing crockery.

    “It’s eerily quiet here in the capital. Lots of people with masks.” Dr Duncan Wood, Mexico City

    Mexico’s Health Secretary, Jose Cordova, said a total of 1,324 people had been admitted to hospital with suspected symptoms since 13 April and were being tested for the virus.

    “In that same period, 81 deaths were recorded probably linked to the virus but only in 20 cases we have the laboratory tests to confirm it,” he said.

    Mexico’s President Felipe Calderon has announced emergency powers to deal with the situation.

    He said he had published a decree through which the government “assumes the faculties and the attributions given by the constitution to the president in case of emergency, like the one we are seeing now”.

    The measures give the authorities the powers to isolate individuals suspected of having the virus and inspect their homes.

    Mr Calderon said Mexico was facing “something unknown” but that the authorities had “large supplies” of the relevant medication.

    ‘International concern’

    In the US, 11 people are now confirmed to have been infected with the new strain – seven people in California, two in Texas, and two in Kansas.

    Eight suspected cases are being investigated at a New York City high school where about 200 students fell mildly ill with flu-like symptoms.

    City health commissioner Dr Thomas Frieden said preliminary tests of the specimens showed they were possible cases of swine flu.

    Further tests will clarify if it was the same strain that detected in the other three states.

    Dr Frieden urged people to maintain basic hygiene, such and covering their mouths when coughing and sneezing, washing hands regularly and keeping surfaces clean.

    Following a meeting of its emergency committee on Saturday, the WHO said the virus had the potential to become a pandemic but it was too early to say whether that would happen.

    WHO Director General Margaret Chan said recent events constituted “a public health emergency of international concern” and that countries needed to cooperate in heightening surveillance.

    The WHO has set a worldwide pandemic alert of level three, meaning a new virus has been confirmed but there is no or limited evidence of human to human transmission.

    Face masks are handed out, while the head of the WHO voices concern

    The highest alert on the six-point scale warns of “efficient and sustained human-to-human transmission”.

    Raising the alert level could lead to travel advisories, trade restrictions and border closures.

    The WHO is advising all countries to be vigilant for seasonally unusual flu or pneumonia-like symptoms among their populations – particularly among young healthy adults.

    Officials said most of those killed so far in Mexico were young adults – rather than more vulnerable children and the elderly.

    Early days
    At least some of the detected flu cases show a new version of the H1N1 swine flu sub-strain – a respiratory disease which infects pigs but only sporadically infects humans.

    H1N1 is the same strain that causes seasonal flu outbreaks in humans, but the newly-detected version contains genetic material from versions which usually affect pigs and birds.

    The virus is spread mainly through coughs and sneezes.

    There is currently no vaccine for the new strain but severe cases can be treated with antiviral medication.

    Officials at the US Centers for Disease Control (CDC) have said that with cases arising in so many areas, containing the virus was no feasible.

    Tom Skinner of the CDC told the BBC that it was too early too tell how efficiently the virus was spreading and what its impact would be.

    He said the US was likely to take “normal and routine” steps within the next few days to screen passengers coming into the US and to distribute information, he said.

    The CDC is sending experts to Mexico to help investigate the virus.
