the havana syndrome, part 4: what it could be and how experts will try to crack the case  -  chemical spill absorbent
Eric Arts, a college student in his 1980 s, was struggling to understand what we now know about AIDS, recalling the confusion of those looking for the cause of AIDS.
It is a mystery that he likened to the present mystery of Canadian and American diplomats who were ill while serving in Havana and suffered pain, loss of memory, dizziness and brain damage.
"It takes a long time to sort out HIV and how it spreads, and the diseases it causes.
It's not something that happened overnight, "says Arts, who is now chairman of the Department of Microbiology and Immunology at the Western University School of Medicine.
The Havana syndrome troubles diplomats serving in Cuba.
It took a lot of effort for Andrew King/PostmediaIt's illustrations to make sure it's an infection, "but it took years to find the cause later.
Even the discovery has caused controversy, he said.
Art says the most difficult but important step in solving the problem of sick diplomats is to cross the starting point --
Figure out what category this new medical condition belongs.
Once scientists know the scope of the problem, it becomes a matter of narrowing down the precise details.
But first, they have to take the key first step, which hasn't happened yet.
Could it be some kind of virus? Or a bacterium?
Or contaminated drinking water?
The planned sonic attack?
All of this and more are widely mentioned.
All kinds of possibilities even include the cries of crickets.
Health scientists may start by looking for patterns, he said.
"They will contact tracking to see who has been in contact with who and who has these symptoms," he said . ".
"In international situations, organizations like who are often needed," he said . ".
This has played a role in the outbreak of Ebola and other mysterious diseases.
"You need to deploy quickly on the ground.
"There is not much you can do before you find its origin and the way it is transmitted --
If it's an infectious disease
If Cuba conceals what it knows, as some have said, "it will make it more difficult," because such research cannot be carried out at a long distance.
Here are some of the reasons for speculation, which are not provided in particular order here: the sound attack, mainly because many victims have reported a sudden hearing of harsh high voicespitched sound.
Humans can hear about 20 waves per second, or Hertz (Very low sound)
To 20,000Hz
Although we can't hear the sound, the sound waves still exist.
On the other hand, the impact of the sound being too low to hear is also controversial.
Some of Ontario's opposition to wind turbines comes from turbine neighbors who believe that this "sub-sound" can cause health problems.
There were also voices in Havana's mystery; • Crickets. Yes, crickets.
After some diplomats reported buzz and "harsh screams --
And made a recording.
A British and Australian team found it in the Indian islands.
As a possible source, there are cricket and cricket.
They reported last month that the cricket sound recorded here "matched in detail" with the record in terms of duration, pulse repetition rate, power spectrum, pulse rate stability and oscillation of each pulse ".
"There have also been accusations of Jamaican cricket originating in Cuba;
Gryllus assimilisotwp electronic attack, using a powerful and focused microwave energy beam, can cause pain or weakness.
Microwaves can enable the brain to perceive sound in places where there is no sound, a phenomenon known as the Frey effect, which some feel coincides with the sound perceived by victims of Havana syndrome;
Some Americans, including the United StatesS.
President Donald Trump has directly accused Cuba of creating some type of attack, which Cuba strongly denies;
Chemical leakage or other environmental contaminants in air, soil or water.
This may also include contaminants in buildings.
A substance called urea formaldehyde foam insulation (UFFI)
Popular in Canada in its 1970 s, but banned because of the gas it emits causing headaches, fatigue, general discomfort and irritation in the eyes, nose and throat.
The problems in Cuba show that environmental toxins are more important than infectious diseases, Arts said.
He said it may be difficult to track exposure to this pollutant over time as it may break down.
"There is something in the water system that you need to take samples, test the water, test the soil, and test the environment.
. . . . . . Your time window is very limited when you can do this.
"Collective hysteria" refers to the symptoms transmitted by the implied power.
• Spread of human diseasesto-human.
Art studies the tropics and the new tropics
Tropical diseases, especially in Africa, would be "unique" if the situation in Cuba was indeed a disease ".
If this is an infectious disease, "it will be resolved relatively quickly" once Western governments decide to concentrate on solving the problem ";
• Non-communicable diseases
Human contact, such as viruses or parasites carried by animals.
"For example, the Hantan virus is transmitted by deer rats," Art said . ".
This will make it difficult to identify patients by examination only after they return to Canada.
