Tense Vigil in China as Nasty Flu Virus Stirs Back to Life

31

By Christina Larson

Science – As flu season bears down, the world is warily eyeing China. A novel H7N9 avian flu strain emerged here in March, infecting at least 135 people and killing 45 before petering out in the summer. Now it is back, with four human cases in southern China in the past month. More cases are a certainty, and researchers, public health experts, and vaccinemakers are preparing for the remote but real possibility that H7N9 will explode into a pandemic.

For now, the signs are reassuring. Sustained human-to-human transmission would be needed for H7N9 to cause widespread illness. But so far, there have been only a handful of possible instances of people infecting each other. In 70% of cases, victims are believed to have picked up the virus directly from live poultry, says Masato Tashiro, head of a World Health Organization (WHO) flu collaborating center in Tokyo. H7N9 is “still looking for ways to adapt well to humans,” says George Gao, deputy director-general of the Chinese Center for Disease Control and Prevention (China CDC).

The Poultry Site – A total of 316 persons infected with the outbreak strain of Salmonella Typhimurium have been reported from 37 states, according to the latest report from the Centers for Disease Control (CDC).

According to the latest CDC report – dated 19 August – among 199 ill persons with available information, 51 (26 per cent) have been admitted to hospital; 59 per cent of ill persons are children 10 years of age or younger.

New Vaccines Target Salmonella and Clostridium in Poultry

1The Poultry Site – Salmonella species are bacteria that can cause foodborne illness in humans when they eat contaminated eggs or other poultry products that are inappropriately cooked. By targeting Salmonella through flock vaccination, contamination of eggs and meat can be reduced without the use of broad scope antibiotics.
 
The poultry industry has been looking for ways to reduce its use of antibiotics due to concerns around the emergence of antibiotic resistant pathogens. Since only a very small portion of Salmonella species can cause foodborne illnesses in humans, a vaccine would need to target only these pathogenic species.

Bird flu appears to have spread from human to human

1By Kate Kelland
MSN News — Research published in the British Medical Journal analyzing a family cluster of cases of the bird flu infection H7N9 in eastern China found it was very likely the virus “transmitted directly from the index patient (a 60-year-old man) to his daughter.”
 
Experts commenting on the research said while it did not necessarily mean H7N9 are any closer to becoming the next flu pandemic, “it does provide a timely reminder of the need to remain extremely vigilant.”
