Arabia Weather - For many people, cold weather is considered an annoying thing, which prompts us to spend more time indoors. Consequently, the spread of colds and influenza , especially in light of the presence of the Covid-19 virus.
The transmission of viruses within closed spaces is affected by a group of environmental factors, such as temperature and humidity level, in addition to how the place is used, and the people who occupy the place play a vital role, as their activities, such as talking, eating, and vacuuming the place, play a major role in transmission. Viruses In addition, there are characteristics of viruses themselves, such as surface charge, interactions with other microbes, and the presence of a viral envelope.
In this context, Charles Gerba, professor of virology at the University of Arizona, points out that these complex aspects make the environment for transmitting viruses in the environment inside closed spaces not simple, and despite the complexity, there are two main ways that can contribute to the transmission of pathogens within these spaces. .
One of the widely spread means of transmission of diseases is through contaminated surfaces, such as door handles, table tops, keyboards, light switches, and drinking fountains, as viruses accumulate on these surfaces. Because it is touched directly by infected people, or from the air. When a person touches a surface carrying viruses, and then touches his face, the possibility of infection increases.
The effectiveness of transmission depends on the type of virus and how it is affected by environmental conditions, such as the use of disinfectants. Viruses can remain on surfaces for varying periods, and thus surfaces play an important role in transmitting infection. In addition, aerosols that carry viruses can spread inside buildings. Such as hotels or schools, and poses an additional risk.
Aerosol sources include contaminated water and water, making them an additional means of transmitting microbes.
However, there are additional reasons why cold weather makes it easier for these viruses to be transmitted to as many people as possible, including:
Cold temperatures create ideal conditions for the spread of cold and influenza, as the activity of these two viruses increases during the cold and dry period, and December and February are considered the coldest period of the year, which enhances the activity of these viruses.
While cold temperatures do not directly cause colds or flu, they do affect our bodies' response to illness. Cold weather makes the mucous membranes in the nose and throat less moist, making us more susceptible to infection.
Research shows that some viruses spread better in the air when humidity levels are low, rather than due to cold temperatures. This is especially true for influenza viruses and SARS-CoV-2 , which causes COVID-19 .
Research shows that understanding the effects of weather on the spread of disease can help take more effective preventative action, whether that's through humidifying our surroundings or promoting personal hygiene habits during cold seasons.
To reduce your chance of infection, getting and upping your influenza and COVID-19 vaccinations is essential to protect against serious illness and relieve symptoms, and although Omicron infection may appear similar to the common cold in vaccinated people, it is still best for the unvaccinated to take precautions.
