Colds are common.
These viruses, contrary to popular belief, are most often spread by hand contact with the germs of an infected person and subsequently touching your own nose, eyes, or mouth. Room humidifiers, nose drops, petroleum jelly, throat lozenges, a balanced diet and plenty of rest can all help to relieve a cold's symptoms. In addition, analgesics, decongestants and cough medicine may also be helpful. Antibiotic treatment is not effective. Colds can last 7-14 days although this can vary from person to person.
