WHO’s list of guidance on COVID-19

There’s a lot of information out there about how governments, health professionals and the general public should respond to the COVID-19 pandemic. WHO has published guidance and advice every step of the way. 

During health emergencies like the COVID-19 pandemic, one of WHO’s most vital roles is to gather data and research from around the world, evaluate it, and then advise countries on how to respond.

Among the many mysteries that have vexed scientists about the ongoing Zika epidemic is the question of how, in pregnant women, the virus manages to cross the maternal-fetal barrier.

A woman’s body is usually quite good at protecting her growing baby. There are biological blockades to prevent the transmission of viruses to a fetus through the bloodstream, by way of the placenta; the same path for the nutrients and oxygen that sustain a developing baby.

What Did the U.S. Learn from Ebola? How to Prepare for Bioterrorist Attacks

FOREIGN POLICY  by Siobhán O'Grady                        April 13, 2015
When the Ebola virus spread from Guinea to Sierra Leone and Liberia last spring, the initial international response was labeled a failure. By the time President Barack Obama ordered troops to the affected countries in September, more than 2,400 people were dead.

But in the United States, where major hospitals prepared for an outbreak, there were only four in-country diagnoses, one of which resulted in a death. And some see the urgency of that response as a lesson in how the government can prepare for another public health hazard: a bioterrorist attack.

Arizona Rep. Martha McSally chairs a House subcommittee that will examine over the next few months the threat of bioterrorist attacks and U.S. preparedness to respond to them. She told Foreign Policy that even if a disease outbreak and the use of a biological agent in a coordinated attack are not completely analogous, the response strains similar systems.

“We can learn lessons from other outbreaks that are naturally occurring,” she said. “We can identify weaknesses in our response and even if it wasn’t terrorism, it presses the system at the same level....”

When Ebola hit U.S., CDC guidelines were weaker than those 15 years ago

THE DALLAS MORNING NEWS  by Sue Ambrose                                     Dec. 27, 2014

DALLAS, Texas --When Ebola surfaced in the U.S., federal guidelines to protect medical workers here were weaker than the ones that the Centers for Disease Control and Prevention had in place 15 years earlier, The Dallas Morning News has found.

It’s not known exactly how nurse Nina Pham contracted Ebola while caring for patient Thomas Eric Duncan. Shown here at Texas Health Presbyterian Hospital in Dallas, she was later successfully treated at a National Institutes of Health hospital in Maryland. Agence France-Presse

A review of CDC documents and archived Web pages shows that a 1998 protocol originally written for health care workers in Africa had more protective measures than the one for U.S. caregivers when Thomas Eric Duncan became the first patient diagnosed with Ebola in this country.

Two Dallas nurses were infected with the deadly virus while treating Duncan at Texas Health Presbyterian Hospital Dallas, where he died in early October....

ER doctor discusses role in Ebola patient’s initial misdiagnosis

DALLAS MORNING NEWS 

The Dallas emergency-room doctor who missed signs of Ebola in a Liberian man who later became the first to die of the disease in the U.S. describes the fateful night for the first time.

Dr. Joseph Howard Meier told The Dallas Morning News that when he treated Thomas Eric Duncan in the early morning hours of Sept. 26, he was unaware that Duncan had recently arrived from a country ravaged by the Ebola outbreak in West Africa. He also said he did not realize Duncan had such a high fever.

"I was unaware of a 103-degree fever," Meier said in written answers to questions from the paper, released by his attorney. "It appears in the chart, but I did not see it...."

Sea, Lake, and Overland Surges from Hurricanes (SLOSH)

nhc.noaa.gov

SLOSH Model - Introduction

The Sea, Lake and Overland Surges from Hurricanes (SLOSH) model is a computerized numerical model developed by the National Weather Service (NWS) to estimate storm surge heights resulting from historical, hypothetical, or predicted hurricanes by taking into account the atmospheric pressure, size, forward speed, and track data. These parameters are used to create a model of the wind field which drives the storm surge.

The SLOSH model consists of a set of physics equations which are applied to a specific locale's shoreline, incorporating the unique bay and river configurations, water depths, bridges, roads, levees and other physical features.
