The time from exposure to the source of infection to onset of influenza is likely to be between three and five days, with a maximum time of seven days.

Staph bacteria, including MRSA, can cause skin infections that may look like a pimple or boil and can be red, swollen, painful, or have pus or other drainage. More serious infections may cause pneumonia, bloodstream infections, or surgical wound infections.

Many people carry staph bacteria on their skin without symptoms. Symptoms of a MRSA or other staph infection depend on where the infection is located. Infections of the skin are the most common and cause symptoms such as redness, warmth, pus, and a wound that does not heal. Your doctor may refer to these infections as boils, furuncles, impetigo, or abscesses. Infections can also develop in the blood, bone, bladder, lungs, and other sites.

Answer: This depends on the mode of the HIV transmission and the lifestyle of the HIV positive person. Majority of persons who are infected through blood transfusion develop symptoms on an average from 3 years to 5 years. With the other modes of transmission when the quantum of the virus is low, the person can remain healthy for 8 to 12 years or longer.

Tell your supervisor about any symptoms that might be caused by WNV infection. If you develop severe symptoms such as high fever, stiff neck, disorientation, tremors, muscle weakness, or paralysis, seek medical attention immediately. Be sure to tell your health care provider that you work outdoors. The period between receiving the infected bite and having symptoms is 3 to 14 days. Testing for WNV infection is available. No vaccine is currently available to prevent WNV infection in humans.

It is not yet known whether Mycobacterium shottsii (the dominant species isolated in the current outbreak of striped bass mycobacteriosis in Chesapeake Bay) can infect humans. Concern is warranted because M. shottsii is closely related to M. marinum, a species known to cause disease in both humans and fish. Primary symptoms of human infection by M. marinum include infections of the skin and soft tissues.

Symptoms of bird flu reported in humans have ranged from typical influenza-like symptoms (fever, cough, sore throat, and muscle aches) to eye infections, pneumonia, acute respiratory distress (difficulty breathing), viral pneumonia and other severe and life-threatening complications. Only if you have recently returned from travel to an area where bird flu is present. Depending on your symptoms, dates of travel, and activities, additional testing might be recommended.

About half of people with HIV develop AIDS within 10 years, but the time between infection and onset of AIDS can vary greatly. The severity of the HIV-related illness or illnesses differs from person to person and is dependent on many factors, including overall health status. Today there are promising new medical treatments that can postpone many of the illnesses associated with AIDS.

If you are not immune to mumps and are exposed to this virus, it can take from 15-25 days for symptoms to appear. Some people have no symptoms at all.

The common symptoms are a severe sore throat with a yellow or white coating on the tonsils. The tonsils or the throat are swollen and red. A throat infection is often accompanied by fever, painful swallowing and swollen lymph glands. When suffering from a persistent sore throat you must consult your doctor. Untreated, infections can lead to problems with heart or kidneys.

Almost any persistent digestive disorder could result from a parasite. The most common symptoms are diarrhea and abdominal pain. Other symptoms include nausea, vomiting, gas and bloating, foul-smelling stools, anorexia or weight loss, gastritis, fever and chills, headache, constipation, blood or mucus in stools, and fatigue.

The H5N1 virus currently infecting birds in Asia that has caused human illness and death is resistant to amantadine and rimantadine, two antiviral medications commonly used for influenza. Two other antiviral medications, oseltamavir and zanamavir, would probably work to treat flu caused by the H5N1 virus, but additional studies still need to be done to prove their effectiveness.

In 1999, 62 cases of severe disease, including 7 death, occurred in the New York area. In 2000, 21 cases were reported, including 2 deaths in the New York City area. In 2001, there were 66 human cases of severe disease and 9 deaths. To date, there have been 256 confirmed deaths in the U.S. attributed to the West Nile Virus. No reliable estimates are available for the number of cases that occur worldwide.

This depends on the mode of the HIV transmission and the lifestyle of the HIV positive person. Majority of persons who are infected through blood transfusion develop symptoms on an average from 3 years to 5 years. With the other modes of transmission when the quantum of the virus is low, the person can remain healthy for 8 to 12 years or longer.

In general, it takes 10-14 days to mount a response to a vaccine if it is the body's first exposure. Then it takes approximately seven days after the second exposure.

It may take 2 to 7 days to show symptoms when you catch the flu and the symptoms may last for up to a week.

The symptoms of HPAI in humans are very similar to other forms of influenza: fever, cough, muscle aches and pains, conjunctivitis, digestive and respiratory disorders.

Newborns, particularly those who are premature, have immune systems that are not fully developed. As such, babies are at increased risk for contracting infections. Great care is used in handling infants in the ICN (NICU), and sterile technique is used when working with intravenous lines, central lines, endotracheal tubes, and intravenous fluids and medications. However, infants may still develop infections from bacteria or viruses in the environment.

Clinical signs in humans usually develop within 2 to 8 days of infection and include sudden onset of headache, fever, chills, and weakness. An acutely swollen and painful lymph node (bubo) often appears approximately 24 hours after the start of clinical signs. Some individuals may develop septicemia without a bubo (primary septicemic plague) or septicemia may occur secondary to bubonic plague.

You will have an instant radiant tan from the caramel guide colour. We recommend waiting for at least 6-8 hours after spray tanning before showering or taking a bath to reveal your developed tan.

Cancers are rare in small polyps (less than 1 cm. or 1/4 inch). 50% of polyps greater than 2 cm. in size are cancerous. Fortunately, 70% of polyps discovered on a routine colonoscopy are less than 1 cm. in size- It takes about 10 years for a cancer to develop into a benign polyp.

Unfortunately, Hepatitis often goes undiagnosed because symptoms are mild or suggest only a flu-like illness. Many people have no symptoms at all. The only way to know for sure if you have Hepatitis is to have a blood test. Ask a doctor or needle exchange site where you can get tested, or call the National Hepatitis Hotline at 1-800-465-4837. You are usually safe to get tested within two weeks after potential exposure to know for sure.

Some people get flu-like symptoms such as fever, headache, sore muscles and joints, stomach ache, swollen lymph glands, or a skin rash one or two weeks after exposure to the virus. Most people; however, have no symptoms at all. You might not know if you are infected with HIV. One way to know is to get tested .

Most mosquito bites cause itching and minor irritation. The symptoms of WNv range considerably and about 80 percent of people show no symptoms at all. Up to 20 percent have mild symptoms that may include fever, headache, vomiting and swollen lymph glands or a rash on the torso. These symptoms may last only a few days or persist for weeks. Less than 1 percent becomes seriously ill resulting in symptoms that can include meningitis, encephalitis, or polio-like paralysis.

Initial infection of the oral herpes simplex virus may cause no symptoms or may cause severe flu-like symptoms with mouth ulcers. In recurring infections, sores tend to erupt in the same area (some patients never have any more symptoms beyond the initial infection). The following are the most common symptoms of an oral herpes simplex virus infection. However, each individual may experience symptoms differently.

The less severe form of Legionella infection is Pontiac Fever, which manifests itself as a self-limiting flu-like illness. The incubation period is remarkably short - in terms of hours to several days - and symptoms will include malaise, muscle aches (myalgia), fever, chills and headache. Patients will, however, typically recover completely within one week. Legionnaires' Disease is the more severe manifestation of Legionella infection.

People infected with the current strand of the avian virus (H5N1) have shown everything from typical human influenza-like symptoms (fever, cough, sore throat, and muscle aches) to pneumonia, severe respiratory diseases, and other life-threatening complications. Symptoms of avian influenza may depend on which specific virus subtype and strain caused the infection. Experts believe it highly unlikely that a pandemic influenza virus could be created by terrorists.

The symptoms of avian flu in humans may be similar to those for the common seasonal flu but usually progress more aggressively and may also include:
