The World Health Organization has certified Algeria and Argentina as malaria-free, following three consecutive years where no new cases of the deadly disease have been reported.
The malaria parasite, which kills more than 400,000 people each year, was discovered in Algeria in 1880. Most of the victims are children under the age of five in Africa.
The World Health Organization reports Algeria is the second country in Africa to be recognized as malaria-free after Mauritius, which was certified in 1973. Argentina is the second country in South America, after Paraguay, to be declared malaria-free.
A combination of many factors has made the achievements possible, according to WHO spokeswoman Fadela Chaib.
“It is very good news for Algeria and Argentina, but also for the two continents and globally also,” Chaib told VOA. “It means that malaria can be beaten. But the efforts should continue because we need also to enhance surveillance to be able to detect if any cases of malaria are still present in the country.”
WHO says the two countries eliminated malaria by employing a number of basic, well-proven measures, including insecticide-treated mosquito nets. It says both countries improved surveillance, which enabled them to rapidly identify and treat new cases of malaria. In addition, the two countries provided free diagnosis and treatment within their borders.
In the case of Argentina, WHO says cross-border collaboration with its neighbor Bolivia was critical in combating the disease. It says both countries teamed up to spray more than 22,000 homes in border areas and to conduct widespread malaria testing.
WHO says Algeria’s and Argentina’s unwavering commitment, perseverance and success in combating malaria should serve as a model for other countries.
Both Algeria and Argentina have succeeded in ridding themselves of the deadly malaria parasite without the benefit of a vaccine. Health officials are hopeful this task becomes easier with the recent rollout of the first promising malaria vaccine in Ghana and Malawi. (VOA)
Reductions in Air Pollution yielded fast and dramatic impacts on health-outcomes, as well as decreases in all-cause morbidity, a new study suggests.
The study, published in the journal Annals of the American Thoracic Society, reviewed interventions that have reduced air pollution at its source. It looked for outcomes and time to achieve those outcomes in several settings, finding that the improvements in health were striking.
Starting at week one of a ban on smoking in Ireland, for example, there was a 13 per cent drop in all-cause mortality, a 26 per cent reduction in ischemic heart disease, a 32 per cent reduction in stroke, and a 38 per cent reduction in chronic obstructive pulmonary disease (COPD). Interestingly, the greatest benefits in that case occurred among non-smokers.
“We knew there were benefits from pollution control, but the magnitude and relatively short time duration to accomplish them were impressive,” said lead author Dean Schraufnagel from the American Thoracic Society in the US.
“Our findings indicate almost immediate and substantial effects on health outcomes followed reduced exposure to air pollution. It’s critical that governments adopt and enforce WHO guidelines for air pollution immediately,” Schraufnagel added.
According to the researchers, In the US a 13-month closure of a steel mill in Utah resulted in reducing hospitalisations for pneumonia, pleurisy, bronchitis and asthma by half.
School absenteeism decreased by 40 per cent, and daily mortality fell by 16 per cent for every 100 µg/m3 PM10 (a pollutant) decrease.
Women who were pregnant during the mill closing were less likely to have premature births.
A 17-day ‘transportation strategy,’ in Atlanta, Georgia during the 1996 Olympic Games involved closing parts of the city to help athletes make it to their events on time, but also greatly decreased air pollution.
In the following four weeks, children’s visits for asthma to clinics dropped by more than 40 per cent and trips to emergency departments by 11 per cent. Hospitalizations for asthma decreased by 19 per cent.
Similarly, when China imposed factory and travel restrictions for the Beijing Olympics, lung function improved within two months, with fewer asthma-related physician visits and less cardiovascular mortality.
“Fortunately, reducing air pollution can result in prompt and substantial health gains. Sweeping policies affecting a whole country can reduce all-cause mortality within weeks,” Schraufnagel said.
