By Louise Smith and Paul Wilson, BBC NewsThe global pandemic has left thousands of people without clean drinking water and hundreds more infected with the deadly virus.
As a result, many have sought refuge in remote villages and towns.
But now they are being urged to help build up supplies of clean drinking-water and sanitation in these communities, as well as providing a sense of safety and security.
Key points:Vioxx and its sibling drug Sovaldi are two of the deadliest drugs on the market, with more than 30,000 deaths reported across the world since the pandemic beganVioxta, another brand of the drug, has been cleared by the FDA but has not been approved for use in the UK as it is still being tested for safetyThe Vioxy brand is also still being evaluated for safetyVioxy, the brand of Sovaldi, is a brand of drugs used to treat severe or life-threatening infections.
Viox is also an anti-inflammatories and is widely used to fight the common cold.
But there are many other brands of the virus-fighting drug that are currently on the shelves of pharmacies and health-care centres.
One of the most popular brands, Viovid, is now off the market.
There is also the widely used generic version of the vaccine known as Co-crystal, which is made by Sanofi-Aventis, a French pharmaceutical company.
But the VIOX brand has been approved by the US Food and Drug Administration (FDA) for use as a treatment for a variety of viral infections.
It is also available as a nasal spray, but in the US, the VSOX brand is still only available through the US pharmacies.
It’s also important to ensure that the brand name is not used in the production of the products, which have to be tested for purity, the FDA said in a statement.
The drug is also manufactured in China and is sold in some US pharmacies under the brand names VioX, Vioxa and Viovids.
The brands are marketed by pharmaceutical companies and pharmaceuticals companies in China, the United States, India and Vietnam.
The company that made Vioxty, Sanofi, has also made a generic version.
However, it is also sold as Cozy, a generic formulation of the same drug, and is only available as an injection, said John Rupp, an infectious diseases specialist at the University of California, San Diego.
Vicarious is the brand used in Australia.
It was originally developed to treat pneumonia in people with a cough, but it is now used in children as well.
It is available in many health-food stores.
A number of pharmaceutical companies, including Sanofi and Roche, have also produced products for the VCOX brand, including Vicarious, said Rupp.
While the VOX brand and VIOxy are the most commonly used in health-related markets, there are also some other brands that are not widely used, he said.VIOX and Vioxxx, for example, are not available in Australia and are available only through pharmacies, Rupp said.
The use of different brands of drugs is becoming increasingly popular.
Some countries have been using generic versions of the drugs as an alternative to the brand that is used by the pharma companies, Ropp said.
But others, like the UK, are trying to find alternatives, he added.
Many countries in Europe have also started to use the VOOXX brand, said David Tovey, an epidemiologist at the World Health Organization (WHO) in Geneva.
The WHO has called for more research into how the virus is spreading and how to use vaccines, but the VMOXX brand has not yet been tested for vaccine efficacy.
More than 1,000 people died worldwide in the first three months of the pandemics, but fewer than 200 have died in the past year.
About 70% of the deaths have been caused by the virus.
The UK recorded the largest number of deaths in the epidemic, with about 1,100 deaths.
The other deaths included an Indian man in India who died in hospital in August, and a woman in Australia who died at home in September.
