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.

Who does haemophilus influenza prey on?

Haemophilus influenza is a bacteria that can cause infections in humans, particularly in the respiratory tract, such as pneumonia, bronchitis, and ear infections. It is especially known to cause invasive diseases in young children and those with compromised immune systems.

Why does a virus enter a cell?

it primarily performs as a synthetic mutant antibody. When this occurs it becomes latent. As this occurs the cell becomes permeable, allowing for mutation. It's almost like going shopping for shoes, but coming home with a purse.

How do viruses get from one host to another?

Viruses can be transmitted from one host to another through various routes such as respiratory droplets, close contact with an infected individual, contaminated surfaces, vectors like mosquitoes, or via bodily fluids like blood or saliva. Once a virus enters a new host, it can infect and replicate within the cells of the host, continuing the cycle of transmission.

Is influenza caused by birds?

The Avian "Bird" flu is passed to humans by birds and their saliva and feces. Other forms of influenza that humans can get are also mutations of viruses that birds have had, some are from pigs (like swine flu) and many are from a combination of various swine, human, other, and bird flu strains that "reassort" in a host animal. For more information about how a new strain of the flu can be created through reassortant, see the related question below about what caused the 2009 Swine flu.

Viruses cannot do what?

They can not reproduce without a host as reproductive vector. They have no metabolism and do not preform cellular functions. Viruses are genetic material enclosed in a protein capsid.

Can you catch nemonia going outside in the snow with a chest cold?

Exposure to cold weather alone does not cause pneumonia. However, being in the cold weather with a chest cold may lower your immune system's defenses, making you more susceptible to infections like pneumonia if exposed to the bacteria or viruses that can cause it. It's important to stay warm, rest, and seek medical advice if your symptoms worsen.

What problems can cold weather cause for the elderly?

Cold weather can also lead the elderly to have rheumatic problems.

Constriction of the blood vessels can also cause and abrupt rise in blood pressure.

Cardiac and pulmonary problems are also very common.

What body system is affected by influenza?

There is clothing that will make you look in shape while hiding away those pounds you gained from last week's birthday cake. To look great, look no further than Amazon.com. http://www.amazon.com/SPANX-Slim-Cognito-Body-Shaping/dp/B00157GOYS

Is influenza considered armed and dangerous?

No, influenza is not considered armed and dangerous. Influenza is a contagious respiratory virus that can cause illness ranging from mild to severe, but it is not a deliberate threat and does not possess any physical weapons or intent to harm.

Is lytic cycle a virus or a bacteria?

The lytic cycle is a process that viruses use to replicate within a host cell. It is not a characteristic of bacteria.

What is the cause of influenza AH1N1?

the causes of swine fluenza are pigs only kidding imonly tweleve and researching this subject my self so suck on that hahahahaha the causes of swine fluenza are pigs only kidding imonly tweleve and researching this subject my self so suck on that hahahahaha

Why is influenza so contagious?

Yes, influenza is considered armed and dangerous because this viral and contagious disease kills many people each year. It had been especially dangerous years back when there was no stable vaccine to eliminate the virus.

What type of gram is H1N1 bacteria gram-positive or gram-negative?

neither...it is a virus, and gram-staining, a microbiology tool, is not used to help identify or classify a virus

Does hand sanitizer kill the good or bad germs in your hand?

Hand sanitizer kills both good and bad germs on your hands. It is important to remember that some good bacteria are necessary for maintaining a healthy microbiome on your skin. It is recommended to use hand sanitizer when soap and water are not available and to not rely on it as a daily hygiene routine.

Does the avian flu have a lytic or lysogenic cycle?

I believe it is lytic. Think: colds are fast acting; they don't sit in your cell for years on end. This means they are lytic (fast acting).

Is the west nile viral or bacterial?

West Nile virus is a viral infection, not a bacterial one. It is primarily transmitted to humans through the bites of infected mosquitoes.

Does Tamiflu tablets contain sulfa?

No, Tamiflu (oseltamivir) does not contain sulfa. It is a neuraminidase inhibitor used to treat and prevent influenza virus infections.

Who discovered the 2009 H1N1 flu virus?

It was a team effort. Teams of scientists from the Centers from Disease Control and Prevention (CDC), World Health Organization (WHO), and public health departments from several other nations worked together to identify and isolate the virus that was causing the outbreak in Mexico, California and Texas in the US.

One of the scientists mentioned to have been involved in the analysis was the leading virologist, Wendy Barclay, who on May 1, 2009 determined that there were characteristics of the virus that resembled other viruses that had caused only mild symptoms and she indicated that this new 2009 H1N1 influenza was unlikely to give most people serious symptoms.

It was just prior to that when on April 27, 2009 the CDC Scientists in Atlanta were able to document the genome sequence of the new strain to share with other scientists in their databases. Not long afterward, on May 6, 2009, Canadian scientists from Winnipeg were able to share the full genetic sequencing of the viruses that had struck Mexico and Canada.

The scientists all over the world remain very busy working and sharing information to further various studies of the pandemic flu still underway.

What organism does the influenza infect?

Influenza primarily infects birds and mammals, including humans. It is a virus that affects the respiratory system and can cause symptoms such as fever, cough, and body aches.

What is N95 in relation to the H1N1 influenza?

N95 is a type of respirator mask that is recommended for healthcare workers when caring for patients with infectious diseases like H1N1 influenza. N95 masks can filter out 95% of airborne particles, including viruses, and are designed to provide a tight seal around the face to enhance protection.

Is measles and smallpox the same?

No, measles and smallpox are two different infectious diseases caused by different viruses. Measles is caused by the measles virus (MeV), while smallpox is caused by the variola virus. Both diseases can be prevented through vaccination, but they have different symptoms and levels of severity.

Should you eat eggs when you have a common cold?

Yes, it is generally safe to eat eggs when you have a common cold. Eggs are a good source of protein, vitamins, and minerals that can help support your immune system during illness. However, if you have an egg allergy or any adverse reactions to eggs, it is best to avoid them.

What is the most common injury from influenza?

Typically no injuries are accommodated with the flu. Some people can die if their immune system is substantially weak and they don't receive the proper medical attention. Usually a headache is the first symptom with a sharply rising temperature then the cough and runny nose kicks in.
