Mosquito vs. Mosquito in the Battle Over the Zika Virus

GENETICALLY modified mosquitoes are in the news for good reason: They may be our best hope for controlling the mosquito-borne Zika virus. The Food and Drug Administration has issued a preliminary finding of no significant environmental impact and is seeking public comment on a plan to test them in a field trial in the Florida Keys.

So you might think this will resolve the Zika crisis, which has caught the world’s attention because of an unexpected spike in microcephaly in babies born to women infected during pregnancy and in the incidence of the paralytic Guillain-Barré syndrome in Zika-infected adults.

Viral complacency

The World Health Organization (WHO) last week declared that the Ebola epidemic in West Africa no longer represents an international public-health emergency. But as experts also warned last week, there must be no let-up in improving readiness for the next Ebola outbreak — including the nightmare prospect of an epidemic in the megacities of Africa.

An expert panel of researchers convened by the London-based Wellcome Trust and the Center for Infectious Disease Research and Policy at the University of Minnesota, Minneapolis, warned in particular that support for Ebola vaccine research must not be allowed to slip. Although a successful experimental Ebola vaccine has been developed, much work remains to be done if safe and effective vaccines are to be ready in sufficient amounts to quickly nip future outbreaks in the bud.

What are new symptoms in Ebola?

Survivors of infection by Ebola virus, already known to face vision, hearing and other problems during their recovery, may also be plagued with health issues such as depression, anxiety and nerve damage that surface after they leave the hospital, according to a small spot survey of victims whose care was managed in the U.S.

New symptoms surface in Ebola patients months after initial recovery

Some of the signs and symptoms can persist for months, researchers from the Centers for Disease Control and Prevention in Atlanta found.

Facing Down the World's Deadliest Pathogens in a BSL4 Lab

Ebola, smallpox, plague—the rogue’s gallery of highly infectious deadly pathogens is frighteningly long and their potential for havoc is great, which is why they can only be studied within the tightly controlled confines of a biosafety level 4 (BSL4) facility. The precautions make work in a BSL4 extremely demanding, slow and physically taxing, which is one reason such research lags behind studies of less-lethal organisms.

White House to transfer Ebola funds to combat Zika virus

WASHINGTON (AP) — The Obama administration is to announce Wednesday it will transfer leftover money from the largely successful fight against Ebola to combat the growing threat of the Zika virus, congressional officials say.

Roughly 75 percent of the $600 million or so would be devoted to the Centers for Disease Control, which is focused on research and development of anti-Zika vaccines, treating those infected with the virus and combating the mosquitoes that spread it. The rest would go to foreign aid accounts to fight the virus overseas.

The officials spoke on condition of anonymity because they were not authorized to publicly discuss the matter before the White House announcement.

Insight - Zika mystery deepens with evidence of nerve cell infections

Top Zika investigators now believe that the birth defect microcephaly and the paralysing Guillain-Barre syndrome may be just the most obvious maladies caused by the mosquito-borne virus.

Fuelling that suspicion are recent discoveries of serious brain and spinal cord infections - including encephalitis, meningitis and myelitis - in people exposed to Zika.

Ebola Survivors Protest for Medical Facilities, Livelihood and Stigma

Ebola work on Op SIRONA described as a career highlight

The Ebola virus outbreak in West Africa devastated that region through 2014 and 2015, with more than 11,000 dead, putting the rest of the world on alert and spurring many nations to lend support to the fight against the hemorrhagic fever.

As part of the Canadian government’s contribution against the epidemic, a total of 79 CAF health care and support staff deployed to Sierra Leone in three different rotations from December 2014 to May 2015. The mission, dubbed Operation SIRONA, sent personnel to the UK’s Kerrytown Treatment Unit. The facility wasn’t tasked with caring just for local patients, but rather with caring for the local and international health care workers who had been exposed to the Ebola virus.

CDC lab safety weaknesses in spotlight again

A potential laboratory-acquired infection at the US Centers for Disease Control (CDC) was announcedon 31 March, following several similar failures at the agency and other US government research bodies.

The CDC is currently investigating whether one of its workers diagnosed with a Salmonella infection acquired it due at a lab where research is undertaken on common and treatable pathogens. Preliminary lab tests indicate that the researcher was infected with a strain of Salmonella that matches that being worked on in the lab. The worker is well and has returned to work. No other agency staff were exposed or sickened, and there was no release of the bacteria outside the lab, the CDC said.
