Genomic analysis confirmed that the 2015 death of a 9-month-old Guinean infant from Ebola virus was the result of transmission through the breast milk of her asymptomatic mother, according to a recent case study.

A case study reports evidence of viral replication lingering in the respiratory tract of an infected person, even after their blood was Ebola free.

Ebola virus may linger and continue to replicate in the lungs of patients recovering from infection, even after viral RNA is no longer detectable in their bloodstreams, according to a case study published today (January 5) in PLOS Pathogens. . . .

 . . . Ippolito and his colleagues monitored the Ebola-infected patient, who was moved from West Africa to a hospital in Italy in 2015, over the course of their infection. They found viral RNA and other markers of viral replication in the patient’s lungs five days after such markers were no longer detectable in the blood.

Mosquito-borne diseases like Zika can be extremely sensitive to climatic changes

The combination of climate change and last year’s El Niño phenomenon likely created the perfect playground for the Zika virus to spread rapidly across South America, a new study finds.

Both the Zika virus and the mosquitoes that carry it have been present in different parts of the world for a while. But several factors, including specific climatic conditions, could have catapulted the disease to public health emergency status, according to researchers from the University of Liverpool.

Final Trial Results Confirm Ebola Vaccine Provides High Protection Against Disease

                                               

who.int

23 DECEMBER 2016 | GENEVA - An experimental Ebola vaccine was highly protective against the deadly virus in a major trial in Guinea, according to results published today in The Lancet. The vaccine is the first to prevent infection from one of the most lethal known pathogens, and the findings add weight to early trial results published last year.

The vaccine, called rVSV-ZEBOV, was studied in a trial involving 11 841 people in Guinea during 2015. Among the 5837 people who received the vaccine, no Ebola cases were recorded 10 days or more after vaccination. In comparison, there were 23 cases 10 days or more after vaccination among those who did not receive the vaccine.

The trial was led by WHO, together with Guinea’s Ministry of Health and other international partners.

Birth Defects Among Fetuses and Infants of US Women With Evidence of Possible Zika Virus Infection During Pregnancy

jamanetwork.com - December 13, 2016 - doi:10.1001/jama.2016.19006

In this report based on preliminary data for pregnant women in the USZPR with laboratory evidence of possible Zika virus infection, 6% overall had a fetus or infant with evidence of a Zika-related birth defect, and among women with timing of possible Zika infection exclusively during the first trimester, 11% had a fetus or infant with a birth defect. The birth defects primarily involved included microcephaly with brain abnormalities, such as intracranial calcifications. Preliminary estimates from the USZPR were within the range of 1% to 13% risk of microcephaly following first-trimester maternal Zika virus infection modeled on the outbreak in Bahia, Brazil, lending support to the credibility of these estimates.

Negative Effects Of Zika During Pregnancy More Common Than Realized

           

Juan Pedro, who has microcephaly and turned one-year-old on December 4, sits in a specially designed chair to keep him upright as he is kissed by his sister Jennifer Karine on December 12, 2016 in Recife, Brazil. As many of the babies with microcephaly, believed to be linked to the Zika virus, turn one-year-old in Recife, doctors and mothers are adapting and learning treatments to assist and calm the children. Many of the children are suffering a plethora of difficulties including vision and hearing problems with doctors now labeling the overall condition as 'Congenital Zika Syndrome'.

Colombia Reports Major Rise in Birth Defect Amid Zika Crisis

CLICK HERE - CDC - MMWR - Preliminary Report of Microcephaly Potentially Associated with Zika Virus Infection During Pregnancy — Colombia, January–November 2016

CLICK HERE - Columbia - INSTITUTO NACIONAL DE SALUD - Zika

nytimes.com - by Donald G. McNeil, Jr. - December 10, 2016

Colombia, which suffered a Zika epidemic that peaked in February, has reported four times as many cases of babies born with microcephaly this year as it did in 2015, providing more proof that the Zika virus causes brain damage in infants.

Because births of microcephalic infants peaked five months after the epidemic did, at about nine times the numbers of the previous July, scientists feel sure that the greatest risk is to babies whose mothers were infected during their first trimesters or early in their second.

The numbers were reported in a study released Friday by the Centers for Disease Control and Prevention and conducted jointly by scientists from the C.D.C. and Colombia’s national health institute.

Informal briefing by the Secretary-General on the United Nations' New Approach to Cholera in Haiti

webtv.un.org - 1 Dec 2016

United Nations Secretary-General Ban Ki-moon today apologized to the people of Haiti, expressing deep regret for the loss of life and suffering caused by the country’s cholera epidemic, and outlined the way forward including immediate steps to stem the outbreak and long-term support for those affected – while also highlighting the need for adequate funding of the proposal.

Haiti: UN’s New Approach on Cholera Puts People at Heart of the Response

submitted by John Carroll

                                         

un.org

30 November 2016 – The response to cholera in Haiti will be a “long and thorough battle,” but the United Nations will stand by the Haitian people and authorities, Stéphane Dujarric, the Spokesman for the Secretary-General, on the eve of the launch of the Organization's new approach to tackling the epidemic in the country.

The new approach was announced last August and will be launched by Secretary-General Ban Ki-moon to the UN General Assembly on Thursday, 1 December. It includes rapid interventions in areas where cases are reported and the prevention of future high-risk public health crises.

The new approach on cholera also focuses on people and proposes the establishment of a program of material assistance and support to Haitians directly affected by the disease.

Zika in Fetal Brain Tissue Responds to a Popular Antibiotic

ucsf.edu - by Laura Kurtzman - November 29, 2016

Working in the lab, UC San Francisco researchers have identified fetal brain tissue cells that are targeted by the Zika virus and determined that azithromycin, a common antibiotic regarded as safe for use during pregnancy, can prevent the virus from infecting these cells . . .

 . . . In the new study, published online Nov. 29, 2016, in the Proceedings of the National Academy of Sciences (PNAS), the UCSF researchers determined that the Zika virus preferentially infects brain cells with an abundance of a protein called AXL, which spans the outer cell membrane of several cell types and serves as a gateway for the invading virus . . .
