Ebola Epidemic Advances in West Africa

Monday, July 28th, 2014

July 28, 2014

The worst recorded epidemic of the deadly and highly contagious Ebola virus led the West African nation of Liberia today to close most of its border crossings. Liberia is one of three nations, along with Sierra Leone and Guinea, that are being hard hit by the virus. Liberia’s President Ellen Johnson-Sirleaf also issued restrictions on public gatherings and said areas hit by the virus could be quarantined. The current outbreak of Ebola hemorrhagic fever, which began in  March in southern Guinea, has killed at least 670 people, including the Liberian doctor who was heading his country’s efforts to contain the epidemic. Yesterday, Nigeria’s Arik Air suspended all flights into Sierra Leone and Guinea after Nigerian officials confirmed the first Ebola death in Lagos, Nigeria’s capital and the most populous city in Africa. Meanwhile, medical workers in Guinea were meeting hostility and resistance from residents who blamed them for spreading the disease.

Ebola hemorrhagic fever is characterized by massive internal bleeding as well as diarrhea and vomiting. It is spread by direct contact with such bodily fluids as saliva and blood and by contact with towels and other objects cotaminated by the virus. While animals, including chimpanzees and gorillas, can transmit the virus, the natural source is unknown. There is no cure or vaccine for the disease. Symptoms appear within 5 to 10 days of infection. About 80 to 90 percent of all people who become infected die, though patients who receive treatment while in the early stages of the disease have a slightly better chance of recovery. Treatment consists mainly of rehydration to replace lost body fluids.

As of July 20, Ebola had killed 454 people in Sierra Leone; 314 in Guinea; and 224 in Liberia, according to the World Health Organization (WHO). Forty-five cases, including 28 deaths, were reported in those three countries between July 18 and 20 alone.

Most hemorrhagic viruses have a host, often a rodent or insect, which carries the virus but does not become ill. Scientists have not yet identified the host for the Ebola virus. However, the bushmeat trade is highly suspected of spreading the virus among people. The WHO has warned people against eating raw bushmeat and avoiding contact with infected apes, bats, and monkeys.

Lemurs Threatened with Extinction

Friday, August 10th, 2012

Aug. 10, 2012

Lemurs, long-tailed, furry mammals related to monkeys, are probably the most endangered group of vertebrates (animals with backbones) on Earth, conservationists with the International Union for the Conservation of Nature and Natural Resources (IUCN) have reported. The IUCN, also known as The World Conservation Union, is a federation of government and private conservation organizations that works with countries and organizations around the world to save rare plant and animal species from extinction. Lemurs live in the wild only in the island countries of Madagascar and Comoros, which lie off the southeast coast of Africa. At a workshop in Madagascar, IUCN conservationists classified 23 of the 103 known species of lemur as critically endangered, the highest threat level. In 2008, the IUCN had reported that 8 species were critically endangered. Altogether, 91 percent of lemur species are currently in danger. As a result, these primates are more threatened than any other species of mammal as well as any species of reptile, amphibian, bird, or bony fish, according to the IUCN.

Ring-tailed lemurs have distinctive rings of black and white fur on the tail. Unlike other lemurs, ring-tailed lemurs spend most of their time on the ground rather than in trees. (c) Tom Nebbia, The Stock Market

A poor country, Madagascar in recent years has been wracked by political upheaval that has severely limited government efforts to protect the tropical forests where the lemurs live. Conservationists cited both widespread illegal timber logging and an increase in hunting for bushmeat as reasons for the lemur’s accelerating decline. About 90 percent of Madagascar’s original forests, which once covered most of the island, have been cut down. The island’s lemurs and other tree-dwelling animals now survive in scattered sections of the surviving forests, mostly near the coast.
