Muscle aches caused by a flu virus cannot be accounted for by fluid loss from excretions and emesis alone, because often muscle aches are the first sign of the flu, long before vomiting or diarrhea may ever occur (and they do not occur in most flu infected folk). Instead, it is the increasing body temperature (the fever that is one of the body's most effective responses for killing off heat-susceptible invaders) that causes an increase in water usage at the cellular level....

How to avoid the spread of colds, flu, and other viral infections: THE SHORT ANSWER: For the flu, get a vaccination (flu shot or jab). See more below in the longer answer. For other viral infections such as measles, mumps, etc. there are also vaccinations that should be used. To avoid HIV/AIDS, or other viral sexually transmitted diseases and infections, always use a condom. See below for more. For a common cold there are no vaccinations, so you'll need to avoid anyone sick, stay at...

If you are exposed to an identical version of the flu that you had previously after you have recovered fully from it the first time, then your body should have developed immunity to all genetically identical kinds of flu and you would not get it a second time. However, the flu can change by mutations and if it does change enough that the immune system no longer sees it as identical, then you would not have immunity to the mutated strain. This...

If you forget to counter stain color of Gram positive would be violet or blue . The above answer is good. Here is why the above answer is good. Yes it would still be Violet or blue. Gram positive bacteria are gram positive, because it holds onto the crystal violet stain that washes out of gram negative bacteria. Counterstaining with safranian turns gram negative bacteria pink to red only because the crystal violet has washed out of the gram negative. The lighter safranian has...

You are most likely to get a cold if someone sneezes or coughs over you or near you. To avoid the spread this way, you need to stay at least a 6 foot diameter distance from the person. Cold viruses are in the air on respiratory droplets for a short time after a cough or sneeze. Although they can travel in the air for only a matter of seconds and for only about a six foot diameter around the person who...

Mosquitoes bite you to suck the blood. The female require the same for ovulation. In the process, the insect at times bite the patient of malaria. The malaria parasite enters the stomach of the insect. Growth of the parasite takes place there. The parasite travels to the salivary gland of the insect. When the mosquito bites the next victim, the parasites enters the body of the victim. They go to liver. They multiply there. Then the parasites enter the blood stream. They...

General infections can be divided into two categories, namely systemic infection and local infection, The cause of a systemic infection comprises of bacteria or virus. The main characteristic of such an infection is that it affects the bloodstream of an individual commonly spread from the genetal area. A local infection can be explained as that infection, which does not affect the whole body of an individual. Rather, it is limited to a specific portion of the body. It does not attack the bloodstream...

'Protozoans' is the term usually used to talk about the protists that cause malaria in humans or in other vertebrate erythrocytes. Protozoa belong to a large group of eukaryotic organisms that are single-celled. These are usually microscopic and include amoeba, ciliates, flagellates and sporozoans. In malaria, the protozoans can also be called 'malaria parasites.' Transmission: The sporozoan protozoa that cause malaria are transmitted through a mosquito feeding upon the blood of an infected host and ingesting a number of these parasites. The protozoa develop within the...

The reason that a doctor performs this examination is to check for a Varicocele. A Varicocele is a swollen varicose vein that may be in the scrotum and is usually on the left side. The physician checks for a hernia, which is when a portion of the intestine decends into the pubic area, and possibly into the testes. When you cough, your abdomen expands/contracts, therefore moving the intestine if it has descended. The doctor can feel this, and determine whether or not...

Catching Flu Twice in a Season Yes, you can. But, it would have to be a different strain or type of the influenza-virus than you previously had (if you are otherwise healthy and have a well-functioning immune system). You would need to be exposed to a different flu virus to get it a second time because your body will have created antibodies to destroy that particular flu virus the first time you had it, and a second exposure that soon should not be...

No. Tamiflu is an antiviral that makes it harder for the flu virus to spread within the body. Antibiotics fight bacteria which would be useless on the flu which is a virus not a bacteria. ...

Your body has different ways to act, depending on the type of pathogen. Many extracellular pathogens get attacked by antibodies, witch stick to the surface of the pathogen and can prevent the uptake of nutrients or from attaching to cells of your body. In many cases these antibodies also facilitate the uptake of pathogens by macrophages, who will digest them. In both cases the pathogen will die and thus be inactivated. The remains can be broken down in your body to serve as...

Several years ago, I developed joint aches and pains for several months following a parvo-virus infection. One of my children (a toddler at the time) had 5th's Disease and my doctor was astute enough to test me for parvo, which is the virus that causes this disease in children. I did feel better eventually, but it took at least 6-9 months I believe. ...

Adults are contagious one or two days before symptoms of the common cold start and approximately a week after. Children can be contagious even longer, as much as two weeks after symptoms have started. You are most contagious earlier in your illness rather than later. Some people can be infected with a common cold virus and have no symptoms, but still spread the virus to others. See the related links section below for a link to more information. ...

No,the person who has once caught measles has the antibodies against measles viruses. When a person has caught measles th T type lymphocytes detect the type of virus and then the B type lymphocytes produce antibodies for the viruses of maesles.Antibodies stick with these viruses and destroy them. This person can not get measles again in life because the antibodies against measeles are already produced for prevntion by catching measles once. These antibodies are memory cell for this specific type of viruses. ...
