Dead Bodies from Natural Disasters Do Not Pose Health Risks, WHO Says

Contrary to popular belief, the bodies of victims of natural disasters rarely pose a health threat to communities, the Red Cross and the World Health Organization (WHO) said, calling for precautions and protection of drinking water sources by keeping the bodies away, according to Agence France Press (AFP).

"Those who survive an event like a natural disaster are more likely to spread disease than dead bodies," noted experts.

Their advice comes after major flooding in Libya and an earthquake in Morocco that left thousands of deaths. When buried under rubble, scattered over it, or floating in water, dead bodies make a terrible scene that often prompts people to rush to bury them.

Authorities often try to bury the dead as swiftly as possible, which can heighten suffering for relatives and create legal problems for victims' families.

Injuries, drowning and burns

Generally, the remains of victims of natural disasters - or wars - do not cause epidemics, because people die as a result of injuries, drowning, or burns, and therefore they don’t carry germs that are likely to cause epidemics, according to the World Health Organization and the Red Cross Society. This means that corpses pose a "negligible" health risk.

However, the case is different with deaths resulting from infectious diseases such as Ebola, Marburg or cholera, or if disaster strikes in an area where infectious diseases are endemic.

"Those who survive an event like a natural disaster are more likely to spread disease than dead bodies," said Pierre Guyomarch, head of forensics at the Red Cross.

Protection of water sources

In the aftermath of any disaster, precautions must be taken to protect water sources, which could become contaminated with feces that come out of dead bodies.

Drinking contaminated water could cause diarrhea or other diseases. The water intended for consumption should simply be disinfected using ordinary means to eliminate dangerous germs.

"It's not the body that's the main cause of danger, it's everything in the water," such as mud and chemicals, noted WHO spokesperson Margaret Harris.

Avoiding rushed burial

But the idea that corpses can spread disease is a misunderstanding which often "pushes people to hastily bury the dead and make it more likely that people will go missing, leaving their loved ones in anguish for years to come," said Bilal Sablouh, regional forensics advisor for Africa at the International Committee of the Red Cross.

The pressure resulting from such rumors in particular could encourage mass burials that are carried out in a hurry and in a way that rarely honors the dead.

"We urge authorities in communities touched by tragedy to not rush forward with mass burials or mass cremations," said Dr. Kazunobu Kojima, medical officer for biosafety and biosecurity in WHO’s Health Emergencies Program.

The WHO and Red Cross recommend the identification of bodies, well managed burials that include easily traceable and properly documented individual graves in demarcated burial sites.

Lime powder does not hasten decomposition, and since dead bodies in disaster or conflict are generally not an infectious risk, the disinfection of these bodies is not needed.

Eggs are less likely to crack when they fall on their side, according to experiments with over 200 eggs.

What does this mean for the best way to crack an egg for breakfast? Not much, since a break around the middle is the best way to get the golden yolk and runny whites to ooze out.

But scientists said it could help with hard-boiling eggs in a pot: Dropping eggs in horizontally may be less likely to cause a stray crack that can unleash the egg's insides in a puffy, cloudy mess.

It's commonly thought that eggs are strongest at their ends — after all, it's how they're packaged in the carton. The thinking is that the arc-shaped bottom of an egg redirects the force and softens the blow of impact.

But when scientists squeezed eggs in both directions during a compression test, they cracked under the same amount of force.

"The fun started when we thought we would get one result and then we saw another," said Hudson Borja da Rocha with Massachusetts Institute of Technology, who helped run the experiments.

The researchers also ran simulations and dropped eggs horizontally and vertically from three short heights up to 0.4 inches (10 millimeters).

The egg result? The ones dropped horizontally cracked less.

"The common sense is that the egg in the vertical direction is stronger than if you lay the egg down. But they proved that's not the case," said materials scientist Marc Meyers with the University of California, San Diego who was not involved with the new study.

Scientists found that the egg's equator was more flexible and absorbed more of the energy of the fall before cracking. The findings were published Thursday in the journal Communications Physics.

Eggs are also usually nestled top-down into homemade contraptions for egg drop challenges as part of school STEM projects, which partially inspired the new study. It's not yet clear whether the new results will help protect these vulnerable eggs, which are dropped at much loftier heights.

It's a bit counterintuitive that the oblong side of an egg could hold up better against a tumble, said study co-author Tal Cohen with Massachusetts Institute of Technology.

Countless broken eggs show "the courage to go and challenge these very common, accepted notions," Cohen said.
