You’ve been doing everything possible to regain your sense of smell, only to find yourself reinfected with Covid. So, what now? Let’s review some important points and stay focused on what you can do to help yourself.
First, let me clarify that, as of writing, there is no specific research on the recovery prospects for people who have experienced smell loss more than once. However, many individuals in our community have shared their experiences of recovering after multiple infections.
Let’s start with some information we do know from studies. Each time you contract Covid, you build some level of immunity. The durability of this immunity isn’t fully understood, but it does offer some protection. Additionally, the SARS-CoV-2 virus has evolved since the pandemic began, and earlier variants appear to have caused more extensive damage to the sense of smell than the more recent ones—likely due to a lack of immunity in the population at the beginning. That said, while the transmissibility of newer variants is still being studied, sticking to preventive measures remains a smart choice to protect yourself and others.
If you’re currently battling an infection, here’s some practical guidance. Start with mouth care, including using a specific type of mouthwash known to reduce viral load in the mouth. Saliva contains a high concentration of the virus, so using mouthwash several times a day is beneficial for two reasons: it reduces the viral load and can help block further spread of the virus. Look for mouthwashes that contain cetylpyridinium chloride (CPC), the ingredient responsible for this action. Brands such as Dentyl Dual Action, Colgate Total Peppermint Blast, Aquafresh Complete Care, and Crest Pro Health include this ingredient. Always check the label to ensure it’s listed.
When using these mouthwashes, remember to just spit rather than rinse your mouth out with water. This allows the residue to remain in your mouth, continuing its antiviral action. Similarly, avoid eating or drinking immediately afterward, so the mouthwash can work without being diluted. The same approach applies to fluoride toothpastes; refrain from rinsing to maximise the protective effect.
Nasal rinsing with boiled water is another effective way to flush out the virus from the nasal cavity and upper airway. You can read more about nasal rinsing advice here. This simple practice can significantly reduce the viral load in the nose, offering extra protection for both you and your family.
You can also use nasal sprays with carageenan such as First Defense, which is made by Vicks. This product has been shown in studies to step a cold within 36 hours if used promptly at the first “tickle”.
Masking, of course, is a way to lower your risk of catching viruses in a general sense, especially in crowded environments.
Taking sensible steps to avoid viruses and reduce them when they happen will provide you with more peace of mind this cold and flu season. Remember, any virus can affect the sense of smell–not just covid.
