Symptoms usually appear within 1-14 days after infection with the bacteria. Average is within 3-5 days.

Symptoms generally begin 2-3 weeks after exposure. The symptoms generally develop slowly, over a period of 2 to 4 days.

Symptoms may begin two to 10 days after becoming infected, with an average of seven days. In persons with healthy immune systems, symptoms usually last about one to two weeks. The symptoms may go in cycles in which you may seem to get better for a few days, then feel worse again before the illness ends.

The incubation period is variable but is normally 3 to 8 weeks. Incubation periods up to several years have been reported. Patients having severe bites or bites about the head usually have the shortest incubation periods.

The child should be taken quickly to the nearest health post, or station where prepacked ORS is available. The trained health worker will then show the parents how to mix ORS and supervise giving it. The health worker should also be able to assess a child who is severely dehydrated who needs hospital treatment (including IV if necessary). During the time before the complete ORS can be started the home-prepared solution should continue to be given.

No. Not everyone gets all the symptoms and they can appear in any order. By knowing the common symptoms of meningitis and meningococcal septicaemia you could save someone's life.

Because symptoms of asbestos exposure take a long time to develop, the time between initial exposure to asbestos and a diagnosis of mesothelioma is often 30 to 50 years.

Many patients notice an immediate relief of symptoms including pain, leg heaviness and fatigue. The complete benefits of the procedure may take 1-2 weeks.

The symptoms of a first outbreak of genital herpes usually appear 2 to 10 days after exposure to herpes and last an average of 2 to 3 weeks. With the first infection, without treatment the sores typically are active (that is, red, irritated, perhaps painful) for 1-2 weeks, then take another 7-10 days to heal completely, so total time from onset to complete healing generally pmtis 2-4 weeks. Recurrent outbreaks are briefer, typically 7-14 days.

Several studies have shown that inorganic arsenic can increase the risk of lung cancer, skin cancer, bladder cancer, liver cancer, kidney cancer, and prostate cancer. The World Health Organization (WHO), the Department of Health and Human Services (DHHS), and the Environmental Protection Agency (EPA) have determined that inorganic arsenic can cause cancer in humans.

It is important to remember that less than 1% of mosquitoes carry the West Nile virus. In rare cases where a bug bite leads to infection, that person may experience mild symptoms such as fever, headache and body aches, occasionally coupled with a skin rash and/or swollen lymph glands. More severe infections may be marked by headache, high fever, neck stiffness, stupor, disorientation, coma, tremors, convulsions, muscle weakness, paralysis and rarely, death.

Bird flu can appear within 1-5 days after contact with the infected material. This is termed as incubation period for the disease.

To date, no cases of SARS have been reported among persons who were exposed to a SARS patient before the onset of the patient's symptoms.

After infection there is an incubation period of 2-14 (OIE) 1-21(USDA) days during which the virus multiplies.
