Malaria scare hits International City in Dubai
----------------------------------------------
Several cases of malaria have been reported in International City (IC)
in Dubai, doctors said. General practitioner Dr Fouziya Ayyub, who
works in IC, said dozens of residents could be infected by mosquitoes
thriving in dirty water bodies in the residential cluster.

"The stagnant waters are mosquito-breeding grounds. People get bitten
and fall sick. When I test them, it turns out to be malaria," said Dr
Fouziya. "As far as I know, there were zero malaria cases here. But
now I see about 2 or 3 cases per week." She added some cases appear to
be "local transmissions" rather than "imported" ones.

The UAE was declared malaria-free by the World Health Organisation in
2007, but there have been incidents of people getting infected abroad
and entering the country.

The Dubai Health Authority (DHA) told XPRESS: "Like any other capital
cities where malaria transmission is eradicated, we do have cases of
imported malaria in the country... People can get the infections and
return to UAE. This is what we call imported malaria." It added: "All
cases reported to DHA in 2011 are cases of imported malaria; all the
cases are expatriates..."

However, Dr Fouziya said some patients had told her they had not
travelled outside the UAE "for a long time." If her suspicions are
true, this would be a case of local malaria transmission, she added.

XPRESS obtained some malaria-positive medical records dated November
through December [2011] from a Dubai clinic, but was unable to verify
how long the patients had stayed in the UAE at a stretch. However, one
Pakistani patient said he was "fine" when he travelled from his home
country to the UAE on 4 Oct 2011. "I was fine back home and doing well
when I landed here. I only fell sick earlier this month -- I was
surprised to find out it was malaria," the 25-year-old said.

Though malaria does not spread from person to person, Dr Fouziya said,
"I would advise people take preventive medicine against malaria and
vaccinations against typhoid because of the unhygienic conditions in
some places in International City and workers' camps."

Another physician, Dr Sarika Raut, said she was also aware of the
cases. "It's very surprising malaria cases have been reported there
recently," said Dr Raut, who practises in Jebel Ali.

Dr Fouziya said patients in IC were initially referred to hospitals
because clinics didn't stock malaria medicine. "We had to order the
pills and are now treating patients."

IC residents say they are under siege by mosquitoes. "We keep our
windows shut and don't step out on the balcony. I tell my children to
rush inside when the school bus drops them off," said an Indian mother
living near plot CBD17, where a water body several meters deep has
collected in a stalled construction site.

Did you know?
-------------
Malaria kills hundreds of thousands of people globally each year and
its symptoms include high fever on alternate days, severe chills and
nausea.

A spokesperson from DHA (Dubai Health Authority) said, "Malaria
transmission is eradicated in the UAE and the country has a WHO
certificate of being malaria-free. UAE worked on eradication of
malaria disease since 1979 and WHO certified UAE-free of malaria in
May 2006.

"However, like any other cities where malaria transmission is
eradicated, we do have cases of imported malaria in the country.

"You may appreciate that Dubai's population is multi-cultural and
Dubai is a multi-ethnic society and there is considerable population
movement from UAE to countries where malaria is holoendemic or hyper
endemic. So the imported malaria is caused either by visiting friends
and relatives back home or during summer vacations to such countries.
Thus people can get infection and return to UAE. This is what we call
imported malaria.

"At DHA, we have a travel clinic covering all travel-related issues in
Al Mankhool Preventive Medicine Centre and Al Muhaisnah Medical
Fitness Centre, where clients are prescribed adequate chemoprophylaxis
and counselling on how to avoid mosquito bites and use mosquito
repellent creams when visiting such countries.

"All cases reported to DHA in 2011 are cases of imported malaria, all
the cases are expatriates and most are imported cases, especially from
India and African countries."

[According to the just released World Malaria Report 2010
(http://www.who.int/mediacentre/news/releases/2010/malaria_report_20101214/en/index.html),
Dubai reported no cases in 2010. A detailed travel history needs to be
obtained. The case referred above of malaria in a Pakistani national
returning some weeks before falling ill, illustrate the difficulty as
this case could easily have been infected in Pakistan. People from
malaria endemic countries can be asymptomatic gametocyte carriers and
may start a local transmission as seen in Greece earlier this year and
in Jamaica in 2006.

MALARIA - UNITED ARAB EMIRATES (ABU DHABI): IMPORTED

Cases of malaria double in a year
---------------------------------
More than 2000 cases of malaria were reported in Abu Dhabi last year, more than double the number in 2010. They all came from outside the UAE, maintaining the country's malaria-free status, which it has held since 2007.

There were 2129 cases in the 1st 9 months of 2011, an increase of more than 1000 on the whole of 2010. Figures for the last 3 months of last year have not yet been released.

Dr Farida Al Hosani, section head of communicable diseases at the Health Authority Abu Dhabi (Haad), said the rise was both expected and welcomed. "We shifted in 2010 to an electronic surveillance system. Previously it was a manual system so the compliance was less, and as the number increases, so does our view of what is happening," the doctor said.

The UAE gained its malaria-free status from the World Health Organisation a decade after reporting its last local case in 1997, and was the 1st country in the Middle East to achieve the status.

Overall, the GCC region has a good record of controlling the disease, said Dr Ziad A Memish, Assistant Deputy Minister for Preventive Medicine for the Ministry of Health in Saudi Arabia and Director of the GCC Centre for Infection Control.

"Out of the whole GCC region, only the southern part of Saudi Arabia and Yemen have cases of malaria. That's where the activity is." The constant flow of expats to and from the UAE, as well as its status as a holiday destination, has led to Haad increasing its focus to pinpoint cases of the disease, said Dr Al Hosani. "For malaria the numbers from 2009 until today have almost doubled. This is not only because the reporting improved, but because there were some outbreaks in nearby countries."

Flooding in Pakistan added to the problem, she said. Other countries where malaria is endemic include India and Malaysia. "The country is receiving large numbers of travellers and foreign workers every year, many of whom come from endemic areas and may have the malaria infection. With the continuing existence of local Anopheles mosquitoes, which pass the disease to humans, transmission of malaria will continue to be a risk," according to the latest volume of Haad's communicable diseases bulletin, which was made public yesterday.

The most obvious symptom of the disease is a fever, said Dr Mohamed Hamad, the infection control chief at Lifeline Hospital. Abdominal pain can also be a sign, said the doctor, who receives on average 3 patients a month with malaria.

Following guidelines issued by Haad, any cases are reported to the authority's infectious diseases department for further assessment. "We send for a blood test and if it comes back positive, we send it to the Centre for Disease Control department at Haad." Most of the doctor's cases come from Pakistan, India and Sudan. Given the somewhat vague symptoms, Dr Memish said doctors must check a patient's history to analyse the problem.

"Usually it is a fever, body aches, back pain or headaches. They are very non-specific and unless you are conscious of it and aware of the person's travel history, then you won't be able to pick it up." According to Haad's report, the mortality rate worldwide has dropped by more than a quarter in the past 12 years, although the drop is marginally higher in Africa. For now, to ensure the UAE remained malaria free, preventive measures will be carried out more frequently.

Alongside workshops for health care professionals, farms will be checked thoroughly for their methods of control, said Dr Al Hosani. "We coordinate with the environmental agency to ensure that malaria breeding is under control. And we inspect farms. The malaria surveillance team will go on a regular basis to farms to monitor the breeding and the control of mosquitoes." Workshops have also been given to companies that supply insecticides to farms, she said. "Since the number of cases of malaria has increased, we need to increase our efforts as well to ensure the best control."

[UAE is not included in the list of countries for which malaria cases are reported in the World Malaria Report. All cases were reportedly imported and early case detection and treatment is important to prevent local transmission. The outbreak of P.vivax malaria in Greece most certainly originated from people infected in endemic areas traveling to Greece for work, a situation very similar to the situation reported in Abu Dhabi.
