Angola Yellow Fever Outbreak, Still A Serious Issue

Angola Yellow Fever Outbreak, Still A Serious Issue – W.H.O

In the on-going battle against the yellow fever outbreak in Angola and the Democratic Republic Of The Congo (DRC), the World Health Organization says although it is currently not a public health emergency of international concern, it however remains a very serious issue.

According to the W.H.O, About 6,000 people in Angola and Democratic Republic of Congo may be infected with yellow fever, six times the number of confirmed cases, but no new infections have been found since July 12; what the organisation describes as an “extremely positive” trend.

However, it was said that the looming rainy season has raised fears of further spread of the worst outbreak in decades of the mosquito-borne hemorrhagic virus.

The outbreak which has killed roughly 400 people since December, now appears to have improved.

With the vaccination of about 7.7 million people this month, in a major campaign in the “high-risk” Congo capital of Kinshasa, along with 1.5 million in other parts of the country, the situation seems to be under control.

Campaigns have depleted the global stockpile of six million yellow fever vaccine doses twice this year already, which the W.H.O says is unprecedented.

The Lantern of the Photuris Firefly

THE lantern, or light organ, of a particular Photuris firefly is covered with jagged scales that dramatically enhance the brightness of the light that the insect produces. * Jagged scales Consider: Researchers have found that tiny scales on the lantern surface of some fireflies form a corrugated pattern, somewhat like overlapping shingles or tiles. The scales tilt up at one end by just 3 micrometers —less than one twentieth the thickness of a human hair. Yet this tiny tilt lets the lantern shine almost 50 percent more brightly than it would if the scales formed an even surface!

An Overview of Indonesia

Oil—How It Affects You

HAVE you ever stopped to think what life for many would be like without petroleum and its products? Oil made from petroleum is used to lubricate motor vehicles, bicycles, strollers, and other things with moving parts. Oil lessens friction, thus slowing the breakdown of machine components. But that is not all.
