What sort of diseases are encountered in Space?

Answer 1

In space there is little to no protection from cosmic rays. Cosmic rays can cause cancer, cataracts and brain damage.
The galaxy is chocked full with these fast moving particles that can rip apart DNA and other molecules. Here on Earth, we are protected from cosmic radiation by the air mass overhead. Astronauts in near-equatorial orbits are shielded by the Earth's magnetic field. Any voyagers going beyond this natural protection will suffer serious health consequences.

Answer 2

None, we bring our own to all the places we've been to.

Any aliens that we meet are unlikely to have diseases that affect us and vice-versa. Just consider how few animal diseases actually propagate to humans.

Now imagine an alien race that might not even have DNA, or have DNA that sufficiently similar, would have diseases that are target for their particular DNA.

If the aliens we meet look exactly like us, then we're seriously screwed. Just consider how many native aboriginals died when Europeans introduced small pox and the common cold to their new found colonies.

Answer 3

Space travelers will be exposed to the short- and long-term effects of this phenomenon. With weightlessness, there are multiple effects, including:

Decrease in heart rate
Decrease in respiratory rate
Loss of body weight
Changes in bone calcium
Redistribution of body fluids with greater amount in the upper body
Decrease in muscle tissue
Weakening of veins and arteries in the legs
Underproduction of red blood cells leading to anemia

Once back on earth, the majority of these changes vanish and most matters revert to normal But there is nonetheless an initial period of weakness and difficulty with balance back on earth that may last several days.

The loss of calcium from bone, however, is a more serious problem, particularly during and after long space flights. The physical stresses on bone and pressures from weight bearing that take place in the presence of gravity are quite clearly necessary for the normal formation, remodeling, and maintenance of bone. The impairment of these normal bone processes in space leads to liberation of calcium from the skeleton. The result is weakened, brittle bone that easily breaks.

Answer 4

Well, since there is no gravity in space you tend to lose blood volume(I think that's the term for it), and you also lose muscle mass. As for diseases, there are none except maybe the germs that hitch a ride with the people that go to space.

Answer 5

Weightlessness

Loss of hearing

Bone Fracture

Night Blindness

Answer 6

nothing space is sterile, space is a vacuum and a vaccuum is devoid of matter therefore there aren't any diseases

Answer 7

Hi. So far none. They all come from the surface of Earth.
