Recently released sequences from Singapore support transmission of D225G. One isolate, A/Singapore/SS003/2010 was from a fatal case (45M), while the other, A/Singapore/SS004/2010 was from an ICU case (37M). Both were collected in April, 2010, and the sequential sample numbers raise the possibility that the two patients were contacts/relatives. Sharing of additional polymorphisms by the two sequences supports human to human transmission.

Recent sequences (collected June 30, 2010) from Nanjing, China also support transmission of D225G and raise concerns this polymorphism is become more common and more easily transmitted. HA with D225G can bind to 2,3 receptors which are found on human lung cells, which may lead to increased concentrations of H1N1 in lung and an unfavorable outcome, as seen in severe and fatal cases.

WHO has maintained that D225G did not transmit, based on a lack of clustering in time and space. However, the recent sequences from Singapore and Nanjing, China show such clustering, as did prior sequences from Ukraine and Russia.

A revised WHO and CDC “working hypothesis” on D225G is long overdue.

Issapharma is a company dedicated exclusively to Personal Protective Equipment for child. Our single and core objective is to protect children against swine flu, bird flu, tuberculosis and other airborne illnesses. It drives our commitment to design and manufacture a line of personal protective equipment that combines advanced performance, comfort and style. We are the exclusive distributor of disposable face masks "Kidmask", a protective respiratory mask specifically adapted for children.

We offer to sell protective N95 masks effective against swine flu for seven to sixteen year olds .

Our N95 respirator mask is designed so that there are no non-contact areas between small children's nasal aperture and the Kidmask. This is the main reason because of what an adult mask could not protect a child against viruses. With the Kidmask, no impure air is allowed into the respiratory passage. The N95 mask has 95% efficiency in filtering airborne particulates virus or bacteria from 0,3 micron. The "N" class means that it is not resistant to oil and the "95" is the filtration efficiency against the solid and liquid aerosols. Though these results do not constitute a warranty. We remind you that single use masks are personal protective equipment to reduce risk of contamination. They are designed to filter and not to kill virus, but they are an excellent way to protect your children .

The influenza virus H1N1 is an acute viral disease that is highly contagious.

Dengue Fever And Insect-Borne Infections Emerging As Public Health Problem In Areas Of The United States

Despite the threat of further introduction of dengue into the mainland United States, as well as the risk of introduction of additional vector-borne diseases, President Obama's 2011 fiscal budget reduces to zero the funding to support the vector-borne infectious disease program at the Centers for Disease Control and Prevention (CDC), the only national program that focuses of detection and outbreak control of vector-borne diseases including dengue, plague, viral encephalitis and Lyme disease.
