You're giving a speech in front of the class, but keep hearing someone coughing, sneezing. and getting tissue. The common symptoms of the common cold. The common cold is a viral infection that primarily targets your nose and throat. The common cold can be caused by over 100 things, and the fact that its contagious makes it even worse. With so many ways for it to be transmitted it’s no wonder that its called the common cold. The common cold is a viral infection that can be cause by numerous things such as droplets in the air,and eating or touching your mouth or eyes without washing your hands. The reason you get so sick is because the virus attaches itself to some part of your respiratory tract. The body then sends white blood cells to get rid of it. Most of the time the white blood cells fail so the body sends more, and thus this is why inflammation occurs. Since the cold is very contagious practically no one is safe, at least completely. Children are the most susceptible to the common cold, because they don't have a strong immune system to get rid of the virus. Children also ten...
..., exposure to any kind of infection such as colds and influenza should be avoided.
Passage 9: “The cells damaged by the virus release chemicals that cause the surrounding blood vessels to swell” (96). This causes inflammation because the blood vessels need to expand to give room for more white blood cells, which fight off sicknesses such as the common rhinovirus. The rhinovirus is often very weak and is responsible for
. There are nearly 62 million cases of the common cold annually in the US
Well at this point, I can almost guarantee that it didn't start at you, you're on the receiving end of a contagious disgusting cold or flu that has grown in size and momentum with each member of the family that it has been so generously shared with.
Influenza is very contagious and spreads rapidly from person to person. Influenza causes worldwide yearly epidemics. According to World Health organization Influenza affects 5-15% world’s population and resulting in 500,000 deaths yearly. Ottenberg stated that, in United States, an average of 200,000 were hospitalized and 36,000 died each year from influenza complications. Influenza is the sixth leading cause of death among US adults and is related to 1 in 20 death in persons older than 65 years. Disease control and prevention estimates indicate that infections like H1N1 which is one of the types of influenza, have resulted in an estimated 42 to 86 million cases and 8520 to 17620 deaths. As I mentioned earlier that infections like influenza are very contagious, they can spread easily from hcw to Patient and back to hcw. The most efficient and effective method of preventing influenza infection is vaccination(The best way to prevent influenza is with annual vaccination).(Sullivan,2010) (Gregory,Tosh &Jacobson, 2005). Motivated by a desire to actively avoid illness Influenza may increase the risk for death in people with existing heart, lung, or circulation disorders. In fact, the higher than average number of winter deaths in people with heart disease may be due only to the occurrence of influenza during those months.Vaccination provides immunity to fight against infection.To increase resistance to harm by modifying the environment to minimize preventable illness (NEED TO CHANGE WORDING)

Many parents have a hard time deciding if their kids are well enough to go to school. Educating both students and parents about signs and symptoms of infection will assist them in making a more informed decision on when a child is too ill for school. According to the CDC, children should stay home if they have fever, cough, sore throat, runny or stuffy nose not associated to allergies, body aches, headaches, chills, tiredness or malaise, diarrhea and vomiting (CDC.gov). One way to safeguard children’s health is to stay up to date with their recommended vaccines. It is also beneficial for them to receive annual flu vaccine. Annual Influenza vaccination has been recommended for all children 6 months to 18 years of age since 2008 by CDC. Research has proven that flu vaccination reduced a child’s risk of respiratory complications related to flu by 60% (CDC.gov).
Weakened immune systems are where you body has a harder time fighting sicknesses and illnesses. So, with a weakened immune system it would be harder to stay healthy and not sick.
Influenza or flu is caused by RNA viruses of the family orthomyxoviridae, that affects the nose, throat, and lungs- the respiratory system. The common symptoms are: fever and respiratory problems, such as cough, sore throat,stuffy nose, as well as headaches and muscle aches. Influenza viruses are spread mainly by droplets made from people coughing, sneezing or talking while having the flu. These droplets can land in the mouths or noses of people or can inhaled into the lungs. It is least common for the virus to spread by touching an infected surface then their mouth or nose. Flu viruses are divided into 3 categories, A, B, C. A and B are responsible for problems in the respiratory system that typically occurs during the winter. Influenza types C is quite different from A and B. Type C only cause mild respiratory symptom or none at all.
Influenza is an acute respiratory illness caused by infection of influenza A and B viruses. The disease can affect both the upper and lower respiratory tract and is often followed by systemic signs and symptoms, such as: sudden onset of fever, chills, non-productive cough, myalgias (muscle pain), headache, nasal congestion, sore throat, and fatigue. (Cox et al.1998). Influenza viruses evolve continuously, challenging mammalian and avian hosts with new variants and causing complex epidemic patterns with regard to age, place, and time. Human influenza viruses cause disease through a variety of direct and indirect pathological effects. The direct effects include destruction of infected cells, damage to respiratory epithelium, and immunological responses that cause general malaise and pneumonia. Indirect effects of infection include secondary bacterial infections due to the tissue damage and other disease such as cardiovascular disease, renal disease, diabetes or chronic pulmonary disease (Schoenbaum S.1996). In the USA, clinical illness affects 5–20% of the population and asymptomatically infects a larger number (Noble G.1982). Infants, who are exposed to influenza epidemics as a novel antigenic challenge after maternal antibodies decline, may have attack rates as high as 30–50% in their first year of life, depending on the frequency of contacts with older siblings (Glezen et al.1997). For reasons, influenza viruses cause epidemics in the northern and southern hemisphere during their respective winters. In the tropics, the timing of activity is less defined, with sometimes year-round circulation or bi-seasonal peaks during the year (Viboud et al.2006).
Water also plays a critical role. When you are dehydrated, your blood and joints are thickened. Your immune system works harder to fight infections. Plus, your energy is too low to for you to do all that you want to, and fight the infection.
From ordinary cold-like symptoms came difficulty breathing, coughing, chronic shortness of breath and eventually, vomiting. Which then caused internal bleeding, and the buildup of fluid in the lungs. For a while, you could cough it out,but eventually, your lungs filled with blood and you died. People who were infected were in the prime of their life, 20’s and 30’s, while the not so young people remained largely untouched.
Influenza is a viral disease that’s communicable and affects an estimated 5-15% of the world's population during the cold seasons and results in 500,000 deaths annually (PL, 2010). Common symptoms that may be experienced
In some diseases, the inflammation is clearly an immune reaction, the body's defense against invading microorganisms. In others, the cause is different or unknown. Infectious Arthritis This disease is most common in young adults. Infection in a joint is usually caused by bacteria or other microorganisms that invade the joint from its blood vessels.
The Flu is the common name influenza which is a virus that attacks the respiratory system. The flu virus releases its genetic information into the cells nucleus to replicate itself. When the cell dies, those copies are released and they affect other cells throughout the rest of the body. With that happening the virus weakens the immune system. When your sick with the flu, your body builds up a defense by making antibodies against it. The flu virus spreads through air when a person coughs, sneezes, or speaks.
