Preparing for a pandemic: Plans for a possible avian flu outbreak

A potentially deadly strain of avian flu that has infected a number of people in China and Taiwan could in the future result in a pandemic, causing researchers to reassess how such an outbreak would be managed.

Known as H7N9, this new strain of bird flu only emerged in 2013. However it has quickly proved to be very dangerous, causing severe respiratory issues and resulting in the death of almost a third of those infected – more than 130 people have believed to have died from the strain to date.

Initially it only seemed to be infecting people who had been in contact with live poultry. Chickens carrying the strain do not show symptoms, so unwary visitors and workers at live poultry markets were mainly affected.

However, there is some evidence that the virus can pass from person-to-person. A recent case saw a woman who was visiting Taipei, Taiwan, from China develop the condition. While she had visited a poultry market before her trip, another member of her tour group also developed the infection, despite claiming to have not been in any contact with poultry.

Similar is the case of a father and son who were infected: the father, who died from the virus, had been in contact with poultry, while the son had not.

There have been a small number of other confirmed cases where the patient had not had exposure to poultry, although the World Health Organisation (WHO) has not released details of their likely source of exposure.

At present the WHO is advising that “There has been no evidence of sustained human-to-human transmission, therefore the risk of ongoing international spread of H7N9 virus by travellers is low.”

However, if this were to change – a distinct possibility in such a new virus – it could spread quickly, causing health services to be overwhelmed.

Major health organisations and governments across the world have long made plans for a possible pandemic.  These include plans for controlling population movement, maintaining effective communication, clinical management and, where possible vaccine programmes.

However, while most of these deal with top-down management from government, some researchers are exploring other options.

Recent research on US hospital management during a pandemic sought to address one particular challenge: satisfying patient preference while ensuring efficient management of resources.

Even during a pandemic, patients want to be able to choose which healthcare facility they visit. But allowing this would result in some facilities being completely overwhelmed while others remain under-used.

Their solution? To provide incentives to patients to encourage them to select the hospitals that make the most sense from a resource management point of view. These would include discounts, fast-track services and transportation.

Research undertaken by Lihui Bai of the University of Louisville, Kentucky and Jiang Zhang of Adelphi University, New York, found that when implemented properly this solution would work as well as forcing patients to attend particular facilities. It would also increase satisfaction, which would be a valuable outcome in such a high-stress scenario.

But for this to work an adequate model needs to be developed before a pandemic occurs. Let’s hope it can be developed in time.

Rollable solar panels on the horizon with the development of flexible ultra-thin glass

Current solar panels are bulky and can be difficult to transport and attach to buildings. But this could change with the development of technology to embed photovoltaics into ultra-thin glass.

The cumbersome nature of existing panels hasn’t stopped solar from becoming a major producer of energy, which could become even more widespread with layers of glass that are as thin as a piece of paper encasing the solar cells.

This could pave the way for solar panels produced in rolls, which could potentially be fixed to an array of everyday household items.

The glass, which is being made by Corning, is not only fracture-resistant and extremely strong, but is so flexible that it can be gently bowed even in its solid form.

Researchers at the Fraunhofer Institute for Applied Polymer Research IAP, Germany, are using organic solar modules as they have advantages over silicon solar cells.

By putting organic solar photovolatics (OPVs) in the glass they are better protected, which could solve the problem of their shorter operating life.

The development is still some way from being able to be implemented on a commercial scale but project manager Danny Krautz said the early testing is showing promising signs.

He said: “We were immediately successful on our first run in producing homogenous layers on smaller substrate dimensions.

“Glass is not only the ideal encapsulating material, it also tolerates process temperatures of up to 400 degrees.”

Flexible solar production methods will only help to increase the amount of energy that will be produced in the future by a rapidly increasing solar market.

The solar revolution is well under way and the demand for cheaper and more accessible ways to implement the technology is rife.

The growth of solar can be seen from just one day in Germany; at the beginning of June solar power produced half of the energy required.

Some in the country think the record could be broken every few months due to the number of new solar panels that are being installed.
