While sanitising everything entering our homes may have been religiously followed last year, home owners may have relaxed this rule, after taking one’s vaccinations and with the low COVID numbers in the last few months after the second wave gradually receded. Now, it is time to get back to the grind again with the coming of the new Omicron variant.

In spite of the rollout of vaccines that also started for the age group of 15-18 years, from January 3, 2o22 and the rollout of booster doses to health workers and senior citizens going forward, one still needs to be cautious and maintain hygiene at home. While every household tries out ways to keep the COVID-19 disease at bay, what about those surfaces that you invariably touch on a daily basis? There have been many debates about whether or not the Coronavirus’ new variant, Omicron, spreads through contaminated surfaces. However, the wise thing to do, is ensure hygiene at all times.

Experts have warned that respiratory droplets on such surfaces, could be a major source for the spread of the Coronavirus. News reached out to Dr Gaurav Singh, senior medical officer, Central Coalfields Ltd and ex-resident, AIIMS Bhubaneswar for some tips.

“It is important to understand that sanitising raw vegetables, milk packets and daily-touch objects was always important and not just because of the Coronavirus. Some people have started using detergent and water for  sanitizing fruits and vegetables for COVID-19. The problem with such techniques, is that it is nearly impossible to prevent contamination due to soap or detergent. Therefore, one may end up with a gastrointestinal infection, as a result of using unscientific ways,” says Singh. To prevent COVID-19 one merely has to follow some simple hygiene practices and follow it, irrespective of whether there is a pandemic or not.

Viruses are assemblies of, say, proteins, nucleic acids, lipids and carbohydrates and need living cells to thrive. Therefore, outside your body, the Coronavirus is as good as ‘dead’. It cannot do anything to surfaces but you can be affected, if you touch the contaminated surface. Now, with the new strain of the Coronavirus named after the 15th letter of Greek alphabet, Omicron can only be confirmed reliably by genome sequencing. COVID test kits with S-gene dropout capabilities can also be used to quickly detect the presence of the Omicron virus.

Viruses do not grow on food but raw vegetables can be a good vehicle for it. Did you know that Hepatitis A was linked to diced tomatoes, lettuce and raspberries? An infected person can contaminate the food and pass on the virus. Seafood, if it comes in contact with faeces of an infected person can also harm you. Viruses have a higher resistance to chemical treatments than bacteria or fungi. So how should you prevent contamination?

  • Wash raw vegetables in hot water or hot water with salt.
  • You could also try washing the vegetables multiple times with potable water to avoid Coronavirus on vegetables.
  • Hydrogen peroxide/potassium permanganate is used by many households but it is far more effective on bacteria than on viruses.
  • If you are using soap and water to clean the raw vegetables, make sure that the remnants of the soap on the surface is also cleaned well. It is difficult to wash off such stains and soap particles. Soap stains are often visible on plates, even after you wash them. The same stands true for vegetables. In fact, it is more difficult to remove soap from the surface of vegetables.
  • It is best to avoid eating raw food/salads now. Cooked food minimises the risk of infection. Make sure food is properly cooked. If you use raw vegetables in salads, clean these with extra care to avoid Coronavirus on vegetables.
  • You may want to wear gloves, when you are handling/buying vegetables and fruits. Make sure you wash these gloves once you are home.
  • Do not place vegetables brought from outside, straight on the kitchen counter.
  • If there are vegetables that cannot be washed as soon as you bring it in, try to keep it in a closed space and do not cook or consume within three to four hours. 
  • Most households use domestic help and cooks, who help us on a day-to-day basis. To be fully satisfied about cleanliness, do the cleaning yourself or train your domestic help to do so.

How long can the Coronavirus survive on surfaces?

The World Health Organization (WHO) guidelines suggest that it is not known how long the Coronavirus can survive on surfaces. “It may persist on surfaces for a few hours or up to several days. This may vary under different conditions (e.g., type of surface, temperature or humidity of the environment),” reads the WHO website. A simple disinfectant is enough to mitigate the harm caused by the virus.
