Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

Ebola Spreads to Liberia, Senegal Shuts Border

EBOLA CONFIRMED IN LIBERIA

Ebola HF cases confirmed in Liberia

At least two cases of Ebola have been confirmed in Liberia, apparently spreading from neighboring Guinea, where the deadly virus has killed 78 people.

The two confirmed cases in Liberia are sisters, one of whom had recently returned from Guinea, said officials.

The highly contagious virus is spread via close personal contact and kills between 25% and 90% of victims.

The first known outbreak in Guinea started in the remote southeastern Forest Region but had recently spread to the capital, Conakry [Population 2.2 million.]

Senegal shuts border with Guinea

Senegal government closed its border with neighboring Guinea soon after confirmation that the virus had reached Conakry.

“When it used to be only in the south of Guinea, we didn’t do anything special. But now that it’s reached Conakry, we believe it’s safer to close our borders,” said Senegal’s Health Minister.

“We have also closed all weekly markets, known as luma, in the south. And we’re having some discussions with religious leaders regarding big religious events,” she added.

Suspected cases of Ebola have also been reported in neighboring Sierra Leone.

Five subspecies of Ebolavirus have so far been found. Four of those have caused disease in humans: Ebola virus (Zaire ebolavirus); Sudan virus (Sudan ebolavirus); Taï Forest virus (Taï Forest ebolavirus, formerly Côte d’Ivoire ebolavirus); and Bundibugyo virus (Bundibugyo ebolavirus). The fifth, Reston virus (Reston ebolavirus), has caused disease in nonhuman primates, but not in humans, according to CDC.

There are no known cure or vaccine for the Ebola virus.

In Africa, confirmed cases of Ebola HF have previously been reported in the following countries:

  • Democratic Republic of the Congo (DRC)
  • Gabon
  • South Sudan
  • Ivory Coast
  • Uganda
  • Republic of the Congo (ROC)
  • South Africa (imported)

“The natural reservoir host of ebolaviruses, and the manner in which transmission of the virus to humans occurs, remain unknown. This makes risk assessment in endemic areas difficult. With the exception of several laboratory contamination cases (one in England and two in Russia), all cases of human illness or death have occurred in Africa; no case has been reported in the United States,” said CDC.

12 deadly pathogens could spread into new regions aided by climate change

A report by Wildlife Conservation Society released on October 7, 2008 lists 12 deadly pathogens that could spread globally as a result of climate change. “All have potential impacts to both human and wildlife health as well as global economies.” Report said.

Titled ‘The Deadly Dozen: Wildlife Diseases in the Age of Climate Change,’ the report illustrates examples of diseases that could spread due to temperatures changes and variations in regional precipitation levels.

Ebola Outbreak Kills Dozens

EBOLA caused deadly fever outbreak: Guinea govt

The Ebola virus caused of an outbreak of deadly hemorrhagic fever which has killed at least 59 people in southern Guinea, government officials said.

Many cases have been recorded since the outbreak began in early March.

The highly contagious virus is spread via close personal contact and kills between 25% and 90% of victims.

Five subspecies of Ebolavirus have so far been found. Four of those have caused disease in humans: Ebola virus (Zaire ebolavirus); Sudan virus (Sudan ebolavirus); Taï Forest virus (Taï Forest ebolavirus, formerly Côte d’Ivoire ebolavirus); and Bundibugyo virus (Bundibugyo ebolavirus).

There is no record of a previous outbreak of Ebola HF in Guinea.

‘Overwhelmed in the field’

“We got the first results from Lyon yesterday (Friday) which informed us of the presence of the Ebola virus as the cause of this outbreak,” a  Guinean health officials told AFP.

“The Ebola fever epidemic raging in southern Guinea since 9 February has left at least 59 dead out of 80 cases identified by our services on the ground.”

“We are overwhelmed in the field, we are fighting against this epidemic with all the means we have at our disposal with the help of our partners but it is difficult.”

Rising Threat of Fungal Infections: Exserohilum Rostratum

Posted by feww on October 11, 2012

DISASTER CALENDAR SYMBOLIC COUNTDOWN: 1,252 Days Left

[October 11, 2012] Mass die-offs resulting from human impact and the planetary response to the anthropogenic assault could occur by early 2016. 

  • SYMBOLIC COUNTDOWN: 1,252 Days Left to the ‘Worst Day’ in Human History

Global Disasters/ Significant Events

Exserohilum Rostratum

Several of the meningitis patients who received epidural steroid injections (medication injected into the spine), have had strokes related to the infection, according to CDC. The meningitis was found to be caused by fungi that are common in the environment but rarely cause infection.


Exserohilum
is a common mold found in soil and on plants, especially grasses. Exserohilum can cause keratitis (eye inflammation), subcutaneous phaeohyphomycosis, endocarditis (inflammation of the lining of the heart), osteomyelitis (bone infection), and sinusitis. (Source: CDC)

Fungal Meningitis Outbreak in the U.S.

  • Case Count: 137  [October 10, 2012 5:45:00 PM EDT]
  • States: 10
  • Deaths: 12

West Nile Virus Infections

“Four thousand seven hundred and thirteen [4,713] human West Nile virus infections have been reported to CDC ArboNET [4,249 cases cited elsewhere on the CDC website] from Alabama, Arizona, Arkansas, California, Colorado, Connecticut, Delaware, District of Columbia, Florida, Georgia, Idaho, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Montana, Nebraska, Nevada, New Hampshire, New Jersey, New Mexico, New York, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Carolina, South Dakota, Tennessee, Texas, Utah, Vermont, Virginia, Washington, West Virginia, Wisconsin, and Wyoming.” CDC reported.

  • 168 deaths reported
  • Cases reported from 47 states and District of Columbia
  • More than 70 percent of the cases have been reported in 8 states: Texas, Mississippi, Michigan, South Dakota, Louisiana, Oklahoma, Illinois and California.
  • Texas reported about 40 percent of all cases.
  • The Dallas-Fort Worth area has reported 33 deaths, the highest number in the country.
  • “The Dallas Morning News reported Wednesday that health officials in Tarrant County, home to Fort Worth, may have vastly underreported cases of the serious neuroinvasive form of West Nile,” a report said.

WNV activity reported from 47 states and DC


West Nile virus (WNV) activity reported to ArboNET, by state, United States, 2012 (as of October 9, 2012). 

U.S. Agri Disaster Areas

USAD has designated 64 counties across six states as agricultural disaster areas. The disaster list also includes independent city of Charlottesville in Virginia and Northern Cheyenne Reservation in Montana.

  • In Montana and surrounding states—Idaho and the Dakotas—losses have been caused by “the combined effects of early spring frosts and freezes, drought, excessive heat, high winds, wildfires, insects, hail, lightning and tornadoes that began Jan. 1, 2012, and continues.”
  • North Carolina counties were designated as disaster areas due to losses caused by excessive rain and flooding that occurred May 14-16, 2012.
  • In Virginia disaster areas were declared due to losses caused by excessive rain, hail, high winds and lightning associated with a derecho.
