As medical doctors have discovered extra concerning the virus, steerage has modified whilst misinformation has flourished. In an effort to offer strong data, The World-Herald, in partnership with the College of Nebraska Medical Heart, is soliciting reader questions on COVID-19.
This week’s solutions had been offered by Dr. Mark Rupp, chief of the UNMC Division of Infectious Ailments and medical director of epidemiology and an infection management at Nebraska Medication; John Lowe, Ph.D., director of analysis for the Nebraska Biocontainment Unit, govt director of schooling for the International Heart for Well being Safety and affiliate professor of environmental, agricultural and occupational well being within the UNMC Faculty of Public Well being; and Dr. Christie Barnes, assistant professor within the UNMC Division of Otolaryngology-Head & Neck Surgical procedure.

Masks work to scale back transmission of the virus from individual to individual. Masks work properly as supply management when worn by somebody who’s contaminated, limiting the quantity of virus an contaminated individual exposes others to. Masks additionally scale back a wearer’s danger of publicity to the virus by lowering how a lot virus the wearer breathes in.
Masks fluctuate in effectiveness. Fabric masks broadly fluctuate in effectiveness relying on match and building whereas surgical masks, KN95 and N95 respirators present a fluid-resistant barrier and filtration. Masks that match snugly to your face and which have a number of layers to filter the air present probably the most safety.
How do I enhance match and performance of masks?
Masks with wire nostril bridges that may be molded to your face have been proven to enhance match. Carrying a well-fitting material masks over a surgical masks has been proven to enhance match and filtration of surgical masks. Tightening ear loops or straps of a masks additionally improves the match of a masks to your face.
How do I’m going about evaluating KN95 to ensure I don’t purchase a counterfeit?
A great place to look when buying KN95s is the Nationwide Private Protecting Expertise Laboratory web site, which lists identified counterfeit respirators.
Key issues to search for in a suspect KN95 embody:
No mannequin quantity offered on the respirator or the packaging.
No itemizing of what requirements the respirator was examined to.
The USA, China and Korea all have related requirements that N95s or KN95s have to be examined to and must be indicated on the respirator packaging.
I’m having a gathering at my house. Ought to I spend money on a HEPA unit?
HEPA (high-efficiency particulate air) filter air cleaners are useful to scale back virus that’s within the air, particularly in residential areas the place the air might not be adequately filtered or recurrently exchanged with contemporary air. An alternate could be to open a window and run a fan to change air extra quickly or transfer gatherings to a well-ventilated house if climate permits.
I’ve had all three vaccinations. Nonetheless acquired COVID. My vaccine-induced antibodies made it very gentle. Does the illness itself empower the immune system with antibodies? What’s totally different, higher about disease-influenced antibodies versus vaccine-induced antibodies? Does safety last more with each?
Sadly, regardless of vaccination, the omicron variant has resulted in substantial breakthrough an infection. COVID-19 sickness occurring in our neighborhood after the primary of this yr is most definitely because of the omicron variant.
Happily, the vaccine has continued to supply wonderful safety towards extreme sickness, hospitalization and dying. The Facilities for Illness Management and Prevention just lately famous that people updated on their COVID vaccinations had been 23 instances much less more likely to be hospitalized than unvaccinated people.
COVID-19 an infection will end in an immunologic response and will additional enhance immunity. We’ve not had sufficient expertise with the omicron variant to know the extent or length of immunologic safety, however, based mostly on expertise, reinfection is uncommon within the first two to 3 months following an infection. Vaccine-induced immunity typically has been extra predictable than disease-induced immunity — which could be spotty and extra transient. Lastly, vaccine-induced immunity comes with out the very actual danger of extreme an infection and lingering signs which can be related to COVID-19 sickness.
My toddler and toddler just lately acquired over their COVID infections. Since they’re nonetheless not approved to get the vaccine, is there any science in how lengthy their pure immunity might final? Is it secure to make use of this time to go to some unvaccinated family members earlier than the following variant arrives?
Though there isn’t any assure of security, there are methods to enhance the security of a gathering between vaccinated and unvaccinated individuals. First, individuals mustn’t come collectively if they’re having signs of an infectious illness. Carrying masks reduces danger. Climate allowing, the assembly could be held outdoors or, if climate doesn’t allow, in a spot with good air flow and/or air filtration.
The most effective guess could be for unvaccinated family members to attenuate the chance of hospitalization and dying as a result of COVID-19 and get the vaccine. Though we hope that omicron would be the final variant to emerge, SARS CoV-2 has been fairly resilient and there’s no good motive to suppose we received’t see future variants.
I acquired COVID 14 months in the past, misplaced my odor and style. I nonetheless can’t odor something. My meals both tastes like steel, rubbish or burnt smoke or is completely the mistaken style for the meals. I’ve tried odor remedy, no change. Is there another remedy?
Sadly, odor loss is quite common with COVID-19 infections. The excellent news is that the overwhelming majority of sufferers regain all or at the least some smelling functionality. Our expertise with odor loss with different corona and higher respiratory viruses is that odor restoration can happen as much as two years after the harm from the virus due to how regenerative the odor nerves are.
The parosmia (irregular odor) and dysgeusia (irregular style) is believed to typically happen within the restoration part of odor. As a result of odor nerves are organized in a particular method within the mind, because the nerves that hook up with these areas are recovering, they will hook up with the mistaken space — ensuing within the mistaken notion of meals or smells (steel, rubbish, and so forth).
Typically, this improves over time and with olfactory coaching, since you are actually coaching your mind to acknowledge specific smells. This takes time, which is why olfactory coaching is a twice-daily remedy over three months. In case you had seen some enhancements, corresponding to with the ability to odor one thing you couldn’t earlier than or style one thing, then I like to recommend persevering with this for longer durations, as that is our greatest remedy so far. It’s like weightlifting to your nostril — the extra effort you set in, the higher the outcomes. It’s useful to see a specialist to measure your odor loss, observe enhancements and moreover determine any confounding causes — corresponding to sinus issues or nasal swelling as a result of allergic reactions — which may be harming your capability to totally get well your odor.
