Latest discoveries: A stream is spread by respiratory droplets culprit
Q: Do you tour led by one pairs of influenza A H1N1 influenza outbreak found that droplets spread of an outbreak of this virus is the culprit, the results published in the latest issue of the U.S. CDC’s “Emerging Infectious Diseases “publication, this adjustment of the impact of prevention and control measures have any effect?
Zeng Light: The survey reached a conclusion: the tour’s first patient talking or coughing, through droplet transmission of the virus to others is the main route of transmission of this outbreak, but did not find evidence of the spread of viruses through the air.
This gives us a more leisurely against the A stream, Dan Ding, increased our confidence. Airborne is the most difficult to prevent, and now we do not fear it, do not have to wear N95 masks a higher level of protection, but also not necessary to disinfect the air, and can rely on to do is to change their behavior, to develop good personal hygiene to protect themselves. Sense can be said that the best vaccine is its own self-discipline, self-discipline is to stress health, manage and droplets, self-serving altruism.
Outcome of the survey, all the people in China, prevention and control, legal protection and social work together to complete the conditions is that the tour visitors through the 300 in the case of search and risk factors of retrospective “queue” research get, rare, with an important guiding significance for the prevention and control, thus winning the respect and attention throughout the world.
Zeng Guang Report: A flow of a “second wave” to the
Q: The Influenza of the “second wave” really come it?
Zeng light: we have to have pairs of influenza A clear understanding of the situation. The current situation presents a number of noteworthy features: First, some unexpected, most of the outbreaks in schools focused on small and medium cities, rather than the big cities shows that the epidemic has now spread to the interior of the country’s central and western regions; two large primary and secondary schools have the outbreak, suggesting that the scope of the epidemic’s spread will be more widely; third, the epidemic has been gradually converted to the local spread of the domestic rather than “imported” the main difficulty in subsequently increasing the prevention and control. As the current accelerated spread of the virus, the epidemic spread to increasingly wide range of incidence has also shown rapid growth trend, it can be said influenza A H1N1 flu “second wave” has begun.
Some people say that the mutated virus is the “second wave” in the beginning, in fact, influenza A H1N1 influenza virus itself is a variant of the virus, whether it needs another variation of continuous monitoring, but even a virus, seasonal difference, which ability to communicate are also different. Now a gradual fall and winter, it is vulnerable to the spread of seasonal influenza viruses, spread easily within families, high-risk groups susceptible to infection, while the number of infections after more, the elderly, children, people who have underlying diseases such as high-risk populations and pregnant women will be more and more affected. 2009 due to suffering from the current global influenza H1N1 flu death toll has reached more than 2,000.
Manage and droplets, can we do?
Q: The droplets spread of influenza A H1N1 virus, force so strong, how do we deal with it?
Zeng light: let the public know that droplet transmission of influenza viruses is the culprit, but did not find the air can spread the virus; the same time, let COPD persons, diabetics, pregnant women, immunocompromised and other high-risk populations and their families to know that influenza viruses the infection may cause serious harm to them.
Response is the need to improve their behavior, really set up good health habits; To fix themselves, self-perfection; rely on its other vaccines, it is better to prevent the initiative. These include: conversation between people do not face each other opposite the standing oblique; conditional statement when people try to keep the two meters outside the anti-droplets of the “safe distance”; wash their hands frequently changes the laundry; sneezing cover mouth and nose with tissue paper when too late to paper can be used to find shelter with the sleeve means; in hospitals and other “easy to dye” environment, wearing masks, masks can be normal; to change certain habits, such as reducing the shaking hands, Gaidiao subconscious dig nose, touching mouth habit; touch handrails finished, I got out after going to the toilet; first time, patients should take the initiative to report on the initiative for the protection of others, wearing masks, consciously rest, isolation. As for the collective unit, not only in schools, factories, companies, military barracks, the detention center should be effective implementation of prevention and control measures, adhere to examine morning newly, early reporting, early control, the suspension of classes, lay-off to be resolute and firm, do not leave things to chance.
Among the people for bad health habits to promote mutual correction, cities, medium and small cities to large cities to study the prevention and control, such as the Beijing Municipal Education Commission, the Health Bureau will hold the university to see the effectiveness of prevention and control.
Because the vaccine research slower than the spread of the epidemic, if we take the above measures leveling the epidemic peak delay in the epidemic development, the vaccine’s development, production and safety of vaccination fight time, on the treatment of critically ill patients to reduce and provided an opportunity for the community economic development, reduces the losses, and ultimately achieving an influenza pandemic to reduce harmful purposes.
Tour an H1N1 influenza outbreak in Sichuan Province Survey
In the tour three flights of 300 visitors in total to 10 second-generation cases, symptoms of fever, sore throat and cough-based. Chengdu – Jiuzhaigou flights, package tours members of morbidity (30%), and Jiuzhaigou joined members of the local morbidity (29%) is basically the same, but not with the first case of the patient sitting in the same plane to fly from Hong Kong to Chengdu 91 passengers , as well as flights from Chengdu, Jiuzhaigou, but did not participate in the tour group of 87 passengers had no illness. At the same enclosed air-conditioned bus ride to Jiuzhaigou tourist passengers, with the first cases in close to talk to 16 people in 9 cases the incidence, attack rates reached 56%, but not to talk to 14 people, although the first cases in constant cough of the same below take the bus nearly seven hours, but not an illness; the same time, talk time of 10 minutes longer than those who attack rate was 80%, higher than the 2-9 minutes to talk, 17%, relative risk was 4.8-fold, and with statistical significance.
