WHO Reports Progress in Containing Ebola Outbreak in Eastern Democratic Republic of Congo

It is impossible to predict where the outbreak is going to go next, said Ryan.

The World Health Organization reports progress in containing the Ebola outbreak in the eastern Democratic Republic of Congo, but says many challenges to its elimination remain.  WHO reports the number of cases in the outbreak now stands at 3,207, including 2,144 deaths.

The executive Director of WHO Health Emergencies, Michael Ryan, says he is largely optimistic that aid workers are getting control of the Ebola outbreak in eastern Congo.  But, he says, it is impossible to say the outbreak is over.

“It is not.  It is impossible to predict where the outbreak is going to go next,” said Ryan. “But… I do–I would stand over the fact that we have significantly contained the virus in a much smaller geographic area.  Now we have to kill the virus.  The problem is, it is back in areas that are deeply insecure.”

In fact, the virus has come full circle.  Ryan notes the disease has moved from Butembo and other urban areas to the remote, rural town of Mangina, the epicenter of the outbreak.  He says the virus is back where it began when the Ebola outbreak was declared August 1, 2018.

“So, essentially the virus is back in the same zone,” said Ryan. “So, the factors that allowed that virus to transmit at low intensity for a number of months, have not changed.  Deep insecurity, reticence amongst the population, distrust and many other factors continue to make this a very dangerous situation.  But a situation, for which I believe we are making significant progress at this time.”

Ryan says WHO is increasing the scale of its operation, engaging in active surveillance across North Kivu province and actively seeking new cases and tracing contacts to keep the virus from spreading.

He says more than 230,000 people have been vaccinated against the deadly disease and more lives are being saved among people infected with the virus who are coming to the treatment centers.

He says the fatality rate among the nearly 800 patients currently in Ebola treatment units is less than one third – a significantly better outcome than the two-thirds fatality rate reported for the disease overall.

Reduction in Air Pollution May Increase Life-Expectancy: Study

Findings of a Research indicate almost immediate and substantial effects on health outcomes followed reduced exposure to air pollution

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.
