Cold and Flu
Questions and answers about the "Common Cold"; symptoms in the upper respiratory tract like sneezing, scratchy throat, and runny nose, but adults don't typically have fevers. Colds are usually caused by the rhinovirus (up to 40% of colds), or Coronaviruses (about 20%), but there are more than 200 viruses that can cause the common cold. Also questions about the seasonal flu, also called "regular flu", caused mostly by Type A and Type B Influenza viruses. Flu starts with similar symptoms as a cold only it hits faster and harder and usually includes fever in adults. Although the "stomach flu" is a common term, it is not a real diagnosis. The proper medical term for stomach flu is gastroenteritis (an intestinal disease, sometimes viral but also bacterial), it is often mistaken for influenza because the flu can sometimes include vomiting and diarrhea.

Influenza is an infectious disease of the respiratory tract that is caused by influenza viruses. It is often called the flu.
Why is the world so frightened of the H5N1 virus?
The H5N1 virus is considered highly pathogenic and has the potential to cause severe illness in humans. It also has a high mortality rate, making it a serious concern for public health organizations and authorities worldwide. The fear is largely due to the virus's ability to rapidly spread and potentially lead to a global pandemic if not contained effectively.
Rhinovirus is mainly spread through respiratory droplets from coughs or sneezes of infected individuals, or by touching surfaces contaminated with the virus. It can also be transmitted through close personal contact with an infected person.
The spray radius of a sneeze is 15 feet. A sneeze is a reflex response using the muscles of the face, throat and,chest,releasing up to 40,000 droplets...
The droplets of a sneeze can travel as fast as 150 feet a second, so If a sneeze takes a little less than a tenth of a second then the answer would be around 15ft, I'd guesstimate the maximum straight line projection at 12 ft.
What causes haemophilus influenza?
Haemophilus influenzae can cause pneumonia, but it is not what causes influenza. Influenza is a disease that is caused by a virus. Haemophilus influenzae is the name of a bacterium. It was originally thought to be the cause of influenza before they had discovered viruses, that is how a bacterium got the name with "influenzae" in it. This type of bacteria also can cause meningitis, septic arthritis, and many other infections, commonly in children under 5 who have immature immune systems. It is a bacterium that can be present without causing illness, unless the person has a suppressed immune system.

Can you catch a cold from going from hot to cold weather?
No. Despite the name a cold really has nothing to do with cold weather. A cold is a virus and can only be caught from pathogens. You wouldn't catch a cold even by being in a tanktop and shorts in winter in Canada. You'd start getting numb and probably sneeze, but that's not a cold.
Would a transformer catch a fire if were cold outside?
It is unlikely for a transformer to catch fire solely due to cold weather. However, extreme cold temperatures can lead to issues with the insulation and components of the transformer, potentially increasing the risk of a fire if there are pre-existing faults or failures in the system. Regular maintenance and monitoring can help prevent such risks.
How come germs cannot live in cold conditions But you get colds and viruses more in the winter?
I'm pretty sure germs can live in cold conditions. Otherwise, we would be perfectly clean in the winter time.

The real reason there is more sickness in winter is because people spend more time indoors and they are careful not to let the "nice warm air out" in other words They don't let the germy air out.
Answer:You normally get more colds in the cooler weather because people tend to stay inside more. By doing so you get more person to person contact than you would in warmer climates. This leads to the spread of the common cold or the influenza virus. This is why its important to cough into your sleeve rather than your hand and to wash your hands often during cold and flu season. Its also a good idea to give up shaking hands and casual pecks on the cheek as kissing can be the easiest way to spread germs around. Anti bacterial soap should be used but not for body cleaning. There are over 50000 good bacteria per square inch on our bodies that keep our skin disease free. If we remove them, we invite skin problems. Another reason people tend to get sick more is most people don't have the common sense to stay at home when they are contageous and wind up giving more gifts around the holidays than most people wanted to receive in the form of a cold. If you have a phlem or mucous productive cough or a runny nose, you are considered to be contageous. Just remember to clean objects like doorknobs, the telephone, the tv remote and anything that gets touched a lot with a 10% bleach and 90% water solution, sprayed out of a spray bottle. This kills 100% of all germs and bacteria including virus'. My family has a rule when anyone is sick. Dont come over unless absolutely necessary.Why does a head cold make you hungry?
During a head cold, the body's immune system is working overtime to fight off the virus or bacteria causing the cold. This increased activity can lead to an increased metabolic rate, which may make you feel hungrier than usual. Additionally, loss of appetite is a common symptom of colds, so when appetite does return, it might feel stronger than usual.
Why do people say brr when it is cold?
People say "brr" when it is cold as an onomatopoeic expression to mimic the sound of shivering or the feeling of being chilled. It is a way to verbally express that they are feeling cold or experiencing discomfort due to the low temperature.
Do golf courses close for cold weather?
Many courses try to stay open until the weather is cold (or snowy) nearly every day. Once the cold weather sets in, many of these courses close for the winter. However, there are some courses that do remain open in one of two forms. Some courses are open if there is a "nice" day. Usually that means a temperature nearl 50 degrees or middle to upper 40's, the greens are not frozen, and the course is not too muddy. Almost always carts will not be permitted because of the damage they may cause to the course in cold weather. Other courses, typically 9-hole courses from my limited observation, remain open in an unofficial sense. They may simply ask you to drop money into a slot and you can play the course (or practice on the course) even though no one is there. Talk to the people who operate the course.
Where does all the bacteria that makes people sick come from?
Bacteria that make people sick can come from contaminated food, water, surfaces, or other infected individuals. These bacteria enter the body through ingestion, inhalation, or physical contact, leading to infections or illnesses. Proper hygiene, food safety practices, and vaccinations can help reduce the risk of getting sick from harmful bacteria.
How does the flu shot affect a CIDP patient?
I have been recently diagnosed with CIDP. I have refused flu shots for the past 10 years because when I would get them I would get sick from the shot then violently ill from the flu later on. I would advise anyone who gets very ill from flu shots be checked by a neurologist for CIDP, indications of neural slowing can be found with an EMG.
What causes body aches with influenza?
When your body is invaded by things like a virus, the immune system sends out white blood cells (also called leukocytes) to find the infection. The white blood cells release a chemical called cytokines, which is what causes the joint pain seen not just in the flu but with many inflammatory/autoimmune conditions like arthritis, lupus, inflammatory bowel disease, etc.
Technically, viruses are not alive, thus they are not a cell. You may be referring to the protein capsid in which the nucleic acid of the virus is enclosed in. The contents of the capsid may vary depending on the virus, but it can be ssDNA, dsDNA, ssRNA, or dsRNA.
When and where do scientists believe influenza started?
There have been many influenza epidemics. There are now two well-known pandemics (covers a much larger world-wide area than an epidemic or a smaller outbreak). The "Spanish Flu" pandemic was in 1918 and 50-70 million people died of the virus. The most recent pandemic was the H1N1/09 "Swine Flu" pandemic beginning in 2009 with some isolated cases still ongoing in 2012.
Where do worms go in cold weather?
Worms burrow deep underground below the frost line to escape cold weather. They create a mucus layer around themselves to protect against freezing temperatures. This allows them to survive the winter months.
Why do balls travel farther in cold weather?
Golf balls do NOT fly farther in cold weather. Anyone who's played golf for several seasons can vouch. But here's the scientific proof.
A chart from the PGA Manual of Golf by Dr. Gary Wiren.
Carry Temp
224 95* F
222 85* F
220 75* F
216 65* F
214 55* F
205 45* F
186 35* F
Also, dry colder air is denser and heavier than hot air (which rises) - which causes more drag, reducing ball flight.
Knocked out, ko ( knocked out ), fainted, fast asleep, blacked out. Unconcious dead, went to sleep fast, not easy to wake out for good Usually a expression meaning passed out, either from being knocked out or drinking too much. Some can be out cold for being a heavy sleeper or from plain exhaustion. Unconsius, how ever you spell it.
Is tepid water better for you to drink than cold water?
There are different opinions concerning this topic because their effects are somewhat different. But majority agree that tepid water is more effective than cold water.

What happens if you continue to sniff rubbing alcohol?
Continuing to sniff rubbing alcohol can cause irritation to the nose, throat, and respiratory system. Prolonged exposure can lead to headaches, dizziness, nausea, and even damage to the central nervous system. It is important to use rubbing alcohol in a well-ventilated area and avoid inhaling it directly.
Yes, warmth to a high fever can cause wax in the ears to melt. If a child is laying on one side of their head and is feeling warm to hot (the weather is hot) this can case ear wax to melt even if the child is not sick. This happens in adults as well. If you haven't had your child to the doctor then do so or at least go to a clinic. Children are well noted for having fevers out of the blue and then disappearing. Don't wait! See a doctor. It will put your mind to rest that your child may have a cold or a bug of some sort.
Freon itself if not cold. Freon can be used to cool things by compressing the gas and then letting it expand. When a gas expands, it cools down (for more information about that, look up the Ideal Gas Law). Freon is very effective for this purpose and because it is a gas with a high heat capacity. Any gas can cool thing in the same way, but Freon does it particularly well. Unfortunately it is what is called a CFC, which destroys ozone in the atmosphere.
Why does high fever alter cellular functions?
Because High Temperatures Damage The Proteins That Are In The Cells. If The Temperature is too high; 40 to 41 degrees Celsius, many of the proteins reach their flocculation point, and they suffer from either precipitation or denaturation.
