Complicated secondary pneumonia after Swine-origin influenza a virus infection in an immunocompetent patient. - We report an immunocompetent patient with methicillin-resistant Staphylococcus aureus (MRSA) and Herpes simplex virus (HSV) pneumonia secondary to S-OIV infection. A 57-year-old man previously without major medical illness was admitted to our hospital with severe pneumonia accompanied by ARDS due to S-OIV. In his clinical course, anti-influenza treatment was not effective. Sputum culture revealed the presence of MRSA, and HSV was isolated in broncho-alveoler lavage (BAL) fluid. Administration of an antiviral agent (acyclovir), an antibacterial agent (linezolid), and a corticosteroid (methylprednisolone) successfully improved the pneumonia and ARDS. HSV pneumonia can scarcely be seen in healthy people. However recently it has been recognized as a ventilator-associated pneumonia. Although co...

The recent emergence of methicillin-resistant Staphylococcus aureus (MRSA) and highly virulent IAV strains has reduced treatment options. Development of an appropriate animal model to study secondary S. aureus infections may provide important information regarding disease pathogenesis. Pigs are natural hosts to both IAV and S. aureus and have respiratory physiology and immune response comparable to humans. To establish a time course of susceptibility to S. aureus after IAV infection, nursery pigs infected intranasally with IAV were challenged with MRSA at different time points. Lung pathology scores and MRSA CFU were evaluated in dual-infected animals after IAV infection. Flow cytomet...

12. Transmission of Influenza A Virus in Pigs - SummaryInfluenza A virus infections cause respiratory disease in pigs and are a risk to public health. The pig plays an important role in influenza ecology because of its ability to support replication of influenza viruses from avian, swine and human species. Influenza A virus is widespread in pigs worldwide, and influenza A virus interspecies transmission has been documented in many events. Influenza A virus is mostly transmitted through direct pig‐to‐pig contact and aerosols although other indirect routes of transmission may also exist. Several factors contribute to differences in the transmission dynamics within populations including among others vaccination, pig flow, animal movement and animal introduction which highlights the complexity of influenza A transmission in pigs.

29 April 2009 — The situation continues to evolve rapidly. As of 18:00 GMT, 29 April 2009, nine countries have officially reported 148 cases of swine influenza A/H1N1 infection. The United States Government has reported 91 laboratory confirmed human cases, with one death. Mexico has reported 26 confirmed human cases of infection including seven deaths.

The following countries have reported laboratory confirmed cases with no deaths – Austria (1), Canada (13), Germany (3), Israel (2), New Zealand (3), Spain (4) and the United Kingdom (5).

Further information on the situation will be available on the WHO website on a regular basis.

WHO advises no restriction of regular travel or closure of borders. It is considered prudent for people who are ill to delay international travel and for people developing symptoms following international travel to seek medical attention, in line with guidance from national authorities.

There is also no risk of infection from this virus from consumption of well-cooked pork and pork products. Individuals are advised to wash hands thoroughly with soap and water on a regular basis and should seek medical attention if they develop any symptoms of influenza-like illness.

(CNN) — Seventy-three cases of swine flu have been confirmed worldwide, the World Health Organization said Monday.

Forty of those cases are in the United States, 26 in Mexico, six in Canada and one in Spain, a WHO representative said.

Later Monday, health officials in Scotland said two cases of swine flu had been confirmed there.

Hundreds more cases are suspected, especially in Mexico, where as many as 103 deaths are thought to have been caused by the virus, the country’s health minister said. More than 2,000 cases have been reported but not confirmed in the country.

Federal officials confirmed 20 new U.S. cases on Monday.

A federal official said they were at the same school in New York in which eight U.S. cases were confirmed earlier. More than 100 students at the school were out with flu-like symptoms last week.

The outbreak is a particular concern because of who it is hitting hard, United Nations Secretary-General Ban Ki-moon said Monday.

“We are concerned that in Mexico, most of those who died were young and healthy adults,” he said.

California Department of Public Health confirms a seventh case of swine flu in the state — and it’s the third in Imperial County.

A 35 year old woman was hospitalized April 4, she recovered and was later released.

At least two cases of the human swine influenza were also confirmed in Kansas Saturday, bringing the U.S. total to 12.

At least eight more are suspected in students at a New York City high school, but health officials say they don’t know whether they have the same virus that has killed scores of people in Mexico.

A strain of the flu has killed as many as 68 people and sickened more than 1,000 across Mexico. The World Health Organization chief says the strain has “pandemic potential” and it may be too late to contain a sudden outbreak.

The U.S. Centers for Disease Control and Prevention in Atlanta says besides the two confirmed cases in Kansas, there are nine in California and Texas.

To date, four cases of swine flu have been reported in San Diego County.

• A 7-year-old male (Friday)
• A 54-year-old male and his 16-year-old daughter (Thursday)
• A 10-year-old male (Tuesday)

All have recovered. Officials say none were exposed to pigs, which is the typical way swine flu is transmitted.

“We have heightened our surveillance and put area healthcare providers on alert. This will most likely generate additional cases of human infection with swine influenza,” Wilma Wooten, M.D., M.P.H., County Public Health Officer said Saturday.

The public is being advised to follow typical precautions, as they should during a regular flu season.

“If you are sick, do not go to work, school or travel. Cover your mouth when coughing, sneezing or blowing your nose, and wash your hands frequently,” Wooten said.

In Mexico, authorities have closed schools, museums, libraries and theaters in the capital to try to contain an outbreak that has spurred concerns of a global flu epidemic.

A hot line fielded 2,366 calls in its first hours from frightened city residents who suspected they might have the disease. Soldiers and health workers handed out masks at subway stops, and hospitals dealt with crowds of people seeking help.

This virus is a mix of human, pig and bird strains that prompted WHO to meet Saturday to consider declaring an international public health emergency — a step that could lead to travel advisories, trade restrictions and border closures. Spokesman Gregory Hartl said a decision would not be made Saturday.

The CDC and Canadian health officials were studying samples sent from Mexico, and airports around the world were screening passengers from Mexico for symptoms of the new flu strain, saying they may quarantine passengers.

But CDC officials dismissed the idea of trying that in the United States, and some experts said it’s too late to try to contain spread of the virus.

They noted there had been no direct contact between the cases in the San Diego and San Antonio areas, suggesting the virus had already spread from one geographic area through other undiagnosed people.

Testing indicates some mainstream antiviral medications seem to work against the virus. The CDC is checking people who have been in contact with the confirmed cases, who all became ill between late March and mid-April.

Health experts say the last recorded death from swine flu in the U.S. was in 1976 and what is significant to the cases here is not the severity, but the strain.

“This is the very first time that it has been detected,” Wooten, M.D., M.P.H said.  And with all the attention, she says it’s unlikely this is the last of it.  “We definitely expect to find more because we’re asking doctors to test.”

Doctors say symptoms of this flu include fever, sore throat, coughing and nausea.

The CDC says two flu drugs, Tamiflu and Relenza, seem effective against the new strain. Roche, the maker of Tamiflu, said the company is prepared to immediately deploy a stockpile of the drug if requested. Both drugs must be taken early, within a few days of the onset of symptoms, to be most effective.
