Geneva:  World Health Organisation (WHO) Assistant Director General Bruce Aylward said here on Tuesday that the “Ebola response is definitely getting better”, adding that though many challenges remain, eliminating the deadly disease is possible in the near future.

Where is Ebola virus found in nature?The exact origin, locations, and natural habitat (known as the "natural reservoir") of Ebola virus remain unknown. However, on the basis of available evidence and the nature of similar viruses, researchers believe that the virus is zoonotic (animal-borne) and is normally maintained in an animal host that is native to the African continent. A similar host is probably associated with Ebola-Reston which was isolated from infected cynomolgous monkeys that were imported to the United States and Italy from the Philippines. The virus is not known to be native to other continents, such as North America.

With crucial improvements in care for contacts, case investigation, and contact tracing being observed, Aylward said that “there is a huge shift now from what was before a report on how many contacts were being seen daily to who are the missing contacts”.

According to Aylward, “this is a very different response to what you would have seen if you were on the ground a month ago”.

“We have gone over the last four weeks from 30 cases, to 25, to seven, and in the last week to two,” said Aylward, who iterated that this decline represents real progress in the fight against the disease which has killed over 11,000 people mainly in Liberia, Sierra Leone, and Guinea, according to Xinhua news agency.

Aylward added that each transmission chain is now being managed on a case by case basis, as “we’re able to treat each chain as an event and look at all the geographies associated with that event”.

This also means that each chain can be ranked by health officials according to the level of risk posed to populations, with experts estimating that there are currently some six transmission chains across the three West African countries.

Despite these trends, Aylward warned that “the biggest risk now is irrational exuberance, or unrealistic expectations”, as unsafe burials or missing contacts infecting new areas may still occur and create new infection points.

He also said that operational challenges linked to the region’s rainy season are hindering response efforts, while dwindling support and reduced financing is further compounding the situation.

Delegates from 114 countries have agreed to take urgent action to end tuberculosis (TB) by 2030, the WHO said.

The announcement on Friday came as the delegates gathered in Moscow for the first WHO global ministerial conference on ending tuberculosis, Xinhua news agency reported.

The delegates promised to achieve strengthen health systems and improve access to the people regarding TB prevention and care so that no one is left behind.

They also agreed to mobilize sufficient and sustainable financing through increased domestic and international investments to close gaps in implementation and research.

Resources are expected to advance research and development of new tools to diagnose, treat and prevent TB, and to build accountability through a framework to track and review progress on ending TB.

“Today marks a critical landmark in the fight to end TB,” said World Health Organisation (WHO) Director-General Tedros Adhanom Ghebreyesus.

“It signals a long overdue global commitment to stop the death and suffering caused by this ancient killer.”

Though global efforts to combat TB have saved an estimated 53 million lives since 2000 and reduced the TB mortality rate by 37 per cent, progress in many countries has stalled, global targets are off-track and persistent gaps remain in TB care and prevention, according to the WHO.

As a result, TB still kills more people than any other infectious disease. Due to its antimicrobial resistance, TB is also the leading killer of people with HIV.

Representatives at the meeting, which was attended by over 1,000 participants, also promised to minimize the risk and spread of drug resistance and do more to engage people and communities affected by or at risk of TB. (IANS)

Goodbye Holy Smoke, Vatican City bans Sale of Cigarettes

The Vatican, a tiny walled city-state surrounded by Rome, is one of the few states to ban smoking.

Vatican City, November 10, 2017 : Pope Francis has ordered a ban on the sale of cigarettes inside the Vatican from next year because of health concerns, a spokesman said on Thursday.

“The motive is very simple: the Holy See cannot be cooperating with a practice that is clearly harming the health of people,” spokesman Greg Burke said in a statement.

He cited World World Health Organization (WHO) statistics that smoking causes more than seven million deaths worldwide every year.

Cigarettes have been sold at a discounted price to Vatican employees and pensioners.

Vatican employees are allowed to buy five cartons of cigarettes a month. Many Italians ask their non-smoking friends who work in the Vatican to buy cigarettes for them because they cost much less than in Italy, where they are subject to heavy taxes.

Burke acknowledged that the sale of cigarettes has been a source of revenue for the Holy See, adding, “However, no profit can be legitimate if it is costing people their lives.”

The spokesman said the sale of large cigars would continue at least for the time being because the smoke is not inhaled.

The Vatican, a tiny walled city-state surrounded by Rome, is one of the few states to ban smoking. Bhutan, where smoking is deemed bad for one’s karma, banned the sale of tobacco in 2005. (VOA)

Women can Boost their Working Memory with Hormone Therapy

Benefits of oestrogen therapy in women.

New York, Nov 5: Undergoing a type of hormone replacement therapy — used for menopausal treatment — may help protect as well as improve working memory for some women as they age, according to a new study.

Hormone replacement therapy uses female hormones – oestrogen and progesterone – to treat common symptoms of menopause and ageing.

The findings showed that women taking oestrogen-only therapy had lower levels of the stress hormone cortisol and performed better on tests of “working memory” following exposure to stress compared to women taking a placebo.

“Our study suggests that oestrogen treatment after menopause protects the memory that is needed for short-term cognitive tasks from the effects of stress,” said lead author Alexandra Ycaza Herrera, a researcher at the University of Southern California – Davis.

To measure the effect of oestrogen therapy on working memory under stress, the team recruited 42 women with an average age of 66.

Half of the postmenopausal women had been on estradiol — a type of oestrogen therapy — for approximately five years, while the others had received a placebo.

The researchers, in the paper published in the Journal of Clinical Endocrinology and Metabolism, collected saliva to measure the women’s levels of cortisol, oestrogen, and progesterone.

They also ran a test of working memory called a “sentence span task”, in which the women were each given a series and then asked whether each sentence made sense. They also were asked to recall the last word of each one.

While women receiving oestrogen therapy had a smaller increase in cortisol and showed no decrease in working memory function, even after being exposed to stressful situation, those taking the placebo experienced a spike in cortisol levels as well as demonstrated a decrease in working memory function.

Previous studies have pointed to potential health risks — the Ahigher risk of breast cancer, heart disease, stroke and blood clots — of the treatment.

Thus, Herrera noted that “hormone replacement therapy may not be right for every woman, but women need to be able to have the conversation with their doctors”.(IANS)
