As we head into fall and winter we see an increase in the number of viral respiratory illnesses in the community. Most of these are simple self-limited infections that healthy individuals can weather after a period of a few days to a week of being uncomfortable from runny noses, sinus congestion, sore throats, coughs, aches and pains and sometimes fever. There are studies out of Scandinavia conducted in extreme cold temperature environments that show that taking an extra gram of Vitamin C per day reduces the number of these infections and the severity and duration in elite athletes and Special Forces military troops. Starting extra vitamin C once you develop symptoms does little to shorten the duration or lessen the intensity of the illness. Vigorous hand washing and avoidance of sick individuals helps as well. Flu shots prevent viral influenza and should be taken by all adults unless they have a specific contraindication to influenza. A cold is not the flu or influenza. Whooping cough or pertussis vaccination with TDap should be taken by all middle aged and senior adults as well to update their pertussis immunity. We often see pictures of individuals wearing cloth surgical masks in crowded areas to prevent being exposed to a viral illness. Those cloth surgical masks keep the wearers secretions and “germs” contained from others but do nothing to prevent infectious agents others are emitting from getting through the pores of the mask and infecting them. If you wish to wear a mask that is effective in keeping infectious agents out then you need to be using an N95 respirator mask.
Once you exhibit viral upper respiratory tract symptoms care is supportive. If you are a running a fever of 101 degrees or higher taking Tylenol or a NSAID will bring the fever down. Staying hydrated with warm fluids, soups and broths helps. Resting when tired helps. Most adults do not “catch” strep throat unless they are exposed to young children usually ages 2-7 that have strep throat. Sore throats feel better with warm fluids, throat lozenges and rest.
You need to see your doctor if you have a chronic illness such as asthma , COPD, heart failure or an immunosuppressive disease which impairs your immune system and you develop a viral illness with a fever of 100.8 or higher. If your fever is 101 or greater for more than 24 hours it is the time to contact your doctor. Breathing difficulty is a red flag for the need to contact your physician immediately.
Most of these viral illnesses will make you feel miserable but will resolve on their own with rest, common sense and plenty of fluids.
