Academics linked to drug industry 'exaggerated' swine flu risk

New research published in the BMJ has suggested that academics with links to the pharmaceutical industry were more likely to give increased risk assessments of the swine flu pandemic of 2009/10 when talking to the media, compared with academics who were not linked to the pharmaceutical industry. Swine flu is a highly contagious respiratory disease found in pigs. The H1N1 influenza subtype is the type that has been known to infect humans, with outbreaks occurring worldwide throughout 2009 and 2010...

(CNN) — From climate change to superbugs, the World Health Organization has laid out 10 big threats to our global health in 2019. And unless these threats get addressed, millions of lives will be in jeopardy. Here’s a snapshot of 10 urgent health issues, according to the United Nations’ public health agency: Not vaccinating when you can One of the most controversial recent health topics in the US is now an international concern. “Vaccine hesitancy — the reluctance or refusal to vaccinate despite the availability of vaccines — threatens to reverse progress made in tackling vaccine-prevent...

It is a rural area, where pig farming is a major economic activity. Although no acute respiratory outbreaks due to swine influenza A viruses (swIAVs) have ever been reported in this free-ranging pig breeding system, influenza A viruses (IAVs) could be circulating within th...

(McMaster University) New data analysis suggests that people born at the time of the 1957 H2N2 or Asian Flu pandemic were at a higher risk of dying during the 2009 H1N1 Swine Flu pandemic as well as the resurgent H1N1 outbreak in 2013-2014. And it is not the first time this has happened.

AbstractSwine influenza viruses (swIAVs) are known to persist endemically in farrow-to-finish pig farms, leading to repeated swine flu outbreaks in successive batches of pigs at a similar age (mostly around 8  weeks of age). This persistence in European swine herds involves swIAVs from European lineages including H1avN1, H1huN2, H3N2, the 2009 H1N1 pandemic virus and their reassortants. The specific population dynamics of farrow-to-finish pig farms, the immune status of the animals at infection-time, the co-circulation of distinct subtypes leading to consecutive or concomitant infections have been evidenced as factors...

Conclusion This study has identified a substance in the mucus secreted by a south Indian frog which can kill certain types of flu virus. Researchers often turn to natural substances with known health-giving properties to find potential new drugs for humans. For example, aspirin was developed based on a compound found in willow bark – which had been used in traditional medicine for hundreds of years. Some other drugs – such as some chemotherapy and anticlotting drugs – have also been developed from chemicals found in plants. By isolating the substances that have an effect the researchers can make sure...

AbstractIn recent years multiple novel influenza A strains have emerged in humans. We reviewed publically available data to summarise epidemiological characteristics of distinct avian influenza viruses known to cause human infection and describe changes over time. Most recently identified zoonotic strains have emerged in China (H7N9, H5N6, H10N8) – these strains have occurred mostly in association with visiting a live bird market. Most zoonotic AIVs and swine influenza variants typically cause mild infections in humans however severe illness and fatalities are associated with zoonotic H5N6, H10N8, H7N9 and H5N1 serot...

Conclusion This modelling study shows how the strains of influenza A – "bird flu" – circulating when a person is born give them lifelong protection against new subtypes with the same H protein groups. The researchers call this immune imprinting. This may help to explain the high severity and mortality rate seen among certain groups. For example, the massive flu pandemic of 1918 was an H1N1 strain. This had a very high fatality rate among young adults, which the researchers consider may have been because when they were born (between 1880 and 1900), H3 was the dominant strain. Therefore they had no prot...

The virus, initially characterized in the farm, was a reassortant Eurasian avian-like H1N1 (H1avN1) genotype, containing a haemagglutinin segment derived from the pandemic ...

ConclusionsThe overall course of illness lasted from 2 to 40 days (median 9 days). Diffused alveolar damage (DAD) was evident in 11 cases, 4 of which had no apparent underlying illness. Obesity was prominent in 12 cases, where three individuals were classified as otherwise healthy. The HA D222G mutation was detected in six cases, 3 of which had no underlying illness. Immunohistochemistry showed the A(H1N1)pdm09 virus to be prominent at the site of inflammation both in close proximity to and inside alveolar structures in the lung tissue. In addition to a possible role for the HA D222G mutation, our findings indica...
