The medical community is scrambling to prepare for the spread of the Zika virus, as a US government agency has issued guidelines for use of traditional and non-traditional medicines.

Dr Raimund Eisemann, the WHO’s director-general, said that there is a need for doctors to be aware of the “current and future risks and complications of these therapies” and that the “immediate need” is for the use of non-standardised treatments, which could lead to a shortage of medicines and the need for them to be withdrawn.

“These are medicines that are widely used around the world, they are used for everything from infections to the management of chronic conditions,” he said in a statement.

“We must be prepared to adapt and to react to the current and future challenges to ensure that the best possible therapies are available to those in need.”

To do so, we need to ensure a thorough assessment of the current risks and the risks of non standardised treatments and to evaluate the appropriateness of each.

“The risk of nonstandardised medicines is extremely high.

The availability of these treatments may lead to shortages and to increased prices for patients and their families.”‘

It is a real challenge’ Dr Eiseman said the WHO was “ready to move” to a more standardised system. 

“It is our job to ensure the quality of life and wellbeing of our people, and this means ensuring that we have the best medicines available to us and we have access to them,” he added.

“It has been a real and growing challenge for the WHO to deal with the challenges that are being faced by countries around the globe.”‘

We are all in danger’ Health officials said there was a real risk of shortages of medicines, with many countries facing the prospect of a shortage in certain areas.

Dr Einman said there were concerns that the Zika outbreak was spreading through countries, and that “we are all at risk”.

“We are witnessing the rise of a new and highly dangerous form of microcephaly, and we are in danger of losing the very people we are trying to help,” he told the conference. 

‘There is a lot at stake’The WHO said that its work in the area of microchimerism and dengue fever had been “intensified” in recent years. 

In an article published in the Lancet Infectious Diseases, Dr Eisman said that “there is a growing and rapidly evolving global pandemic” and the global response “must be in tune with the new challenges that we face”.

“There is still much to do, and the challenge is great, but we are all living in danger,” he wrote.

“There is only so much we can do in this moment.” 

‘People will have to decide for themselves’ The WHO has also called on people to “take the decision for themselves” and to “make sure they know what they are choosing”.

“If people are not comfortable with the risks, they should not be using them.

There is no need for fear,” the agency said. 

The decision on whether to use an approved treatment depends on the circumstances and needs of the individual, with a recommendation based on the medical evidence, the patient’s health and other relevant considerations. 

There are no national guidelines for Zika treatments, but experts say the WHO will have an advisory role in the new system.

The WHO is not alone in its efforts to develop a system for Zika treatment. 

Several international organisations have also been working to develop an alternative system for treating patients. 

WHO spokesman Mark Brown said that the agency was working to “set a new benchmark for the delivery of treatments in the region”.

“The WHO will continue to work closely with the World Health Organisation (WHO) and other international partners to implement this new system,” he was quoted as saying.

“As part of the WHO Global Partnership on Zika, the organisation will work with the WHO, the European Commission and other stakeholders to develop guidelines for the global community.” 

Dr Brown added that the WHO had set up an “assessment and assessment centre” to help doctors to decide how best to use treatments. 

However, he added that it was not yet clear how the WHO would implement the system in the US. 

This is the second time the WHO has announced plans to set up a system.

In January, the agency published a draft report outlining its “first-ever system of global standards for Zika”. 

In May, the World Economic Forum launched an “international process to create a Zika-free region”. 

 WHO chief Dr Francis Collins said: “In this situation, where people will have the choice, and are free to choose, whether to rely on treatments that they may already have in their own countries, or which are currently available, we are not going to lose sight of the fact that we need a system that protects people, that ensures that the most vulnerable people have access
