Clinical testing will ensue regarding the H7N9 virus outbreak that has already left 24% of it’s victims dead.

CHINA — A deadly H7N9 outbreak has slowed up as officials attempt to contain the influenza virus that has been labeled by some as the most “deadly” in the world. However, this does not indicate that we are entirely out of the woods yet. In fact, mortality rates have risen to 24%, an astonishing number, in terms of a viral death rate.
This is nearly a 25% mortality rate as out of 130 known cases reported, 24 of them led to the death of the infected.
Gathering more information on the matter locally Chinese official is still trying desperately to locate the source. While the Center for Disease Control (CDC) now wants to initiate the early phases of human testing. However, some have little faith in the CDC as they have admitted they are unsure of the source.
CIDRAP reported, “China’s agriculture ministry yesterday announced five more poultry and market environmental samples that tested positive for H7N9, according to a report from the World Organization for Animal Health (OIE). They included three environment samples from a live-bird market in Shandong province, one chicken sample from a live-bird wholesale market in Guangdong province, and one chicken sample from a market in Jiangxi province.
Guangdong is the only province to report a positive bird or market sample in the absence of confirmed human H7N9 cases. It is also the southernmost area of China to report positive H7N9 findings. The OIE report said 89,964 birds were destroyed at the Guangdong wholesale market, which is located in Dongguan. The health ministry said the H7N9 virus detected in the samples is similar to that found in a pigeon collected from a market in Shanghai in early April, Xinhua reported yesterday.
Meanwhile, Tom Frieden, MD, director of the US Centers for Disease Control and Prevention (CDC) said the H7N9 virus in its current form can’t launch a pandemic, but could be if the virus mutates to gain the ability to spread readily from person to person, Reuters reported today. He added that predicting H7N9′s next step is impossible. “I cannot say with certainty whether that will happen tomorrow, within the next 10 years, or never.” Frieden told Reuters that the CDC has 193 staff members working on H7N9, with team members in China, Laos, Cambodia, and Vietnam. It activated its emergency operations center (EOC) in early April to monitor disease developments.”
Why is this virus infecting humans now?
“We do not know the answer to this question yet because we do not know the source of exposure for these human infections. However, analysis of the genes of these viruses suggests that although the viruses have evolved in birds, they may infect mammals more easily than other avian viruses.”, According to the CDC, raising eyebrows across the medical community.
What this really means is, that the CDC has no idea what is going on — meanwhile, it’s been openly admitted by officials that the H7N9 is indeed the deadliest flu virus in history.
The publication LiveScience.com reported “The first step is to make a vaccine. Researchers at the Centers for Disease Control and Prevention (CDC) have already made a preliminary “seed vaccine” against strains of the H7N9 virus that have been found in infected people. Earlier this month, the CDC offered to begin shipping this vaccine to manufacturers that wanted to start creating batches to be used in testing.
Next, volunteers in the United States will be recruited for the trial, said Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases. During the trial, health officials will assess the vaccine’s safety (such as whether there are any adverse reactions)….
Some vaccines contain ingredients called adjuvants, which boost their effects. Although adjuvants have not been added to flu vaccines in the United States in the past, the clinical trials of the H7N9 vaccine will include one version with an adjuvant, and one without, Faucitold LiveScience.
Because no cases of H7N9 have been reported in the United States — and because it would be unethical to expose people to the virus just to test the vaccine — the trials cannot directly assess the effectiveness of the vaccine in preventing H7N9 infection.
However, researchers will indirectly test the vaccine’s effectiveness by taking blood from vaccinated people, and checking to see if antibodies in their blood can neutralize (or kill) theH7N9 virus in lab dishes, Faucisaid.”
