Is fever in a newborn always dangerous?

On top of what Hui Qun has mentioned, it is also important to note that there are 2 types of fevers that afflict babies: viral fever and bacterial fever. A viral fever occurs when the body fights off an illness caused by a virus like the flu, or the common cold. Viral fevers tend to subside within three days and antibiotics have no effect on viruses. Bacterial fever, on the other hand, occurs when the body fights off a bacterial infection like a urinary tract infection, or bacterial pneumonia. Bacterial infections are less common than viruses – and more concerning, because they can lead to serious illness if left untreated. Antibiotics are usually required. Generally, if your baby's fever lasts longer than three days, it's time to see a doctor. http://www.babycenter.com/0_fever-in-babies-7-things-you-might-not-know_10373598.bc

A fever in babies can be one of the scariest symptoms for parents, especially when that fever is high or the baby is only a few weeks old. A fever isn't an illness -- it's a symptom of one. A fever usually indicates that the body is fighting an illness. If your baby has a fever, in most instances it means he has picked up a cold or other viral infection. Although they are less common in infants, pneumonia, urinary tract infection, ear infection, or a more serious bacterial infection, meningitis, may be causing a fever. If required, please proceed to the nearest hospital.

Fever in babies younger than three months old could be a sign of infection and should be brought to a doctor. Because their immune systems are still developing, they are at higher risk for severe infections. If a newborn has a fever of over 38 degrees, please bring him/her to the doctors. Also, if the baby has a body temperature of lower than 35.6degrees, it is also a cause of concern and medical attention is needed.

Fever is a sign of infection. You should worry if the temprature more than 38C. If you breastfeed, go give your baby as many breastmilk as you can before you go to doctor. Hug him and don't forget skin to skin contact, it helps to reduce the fever.

For infants less than 3 months, their immune systems are still developing which leaves them at higher risk for severe infections, thus if the temperature is abnormal, you should send your baby to the doctor right away.

With newborn, it is best to practise everything with caution. Measure the temperature and if it is above 37.5, bring to the doctor for a check.
