Some feel that the Christmas spirit isn’t floating in the air this holiday season, but rather fear of the corona virus, and how it will be handled this winter. With temperatures dropping as fast as these store prices on sale, many worry how will the U.S stop cases from spiking as much as it did earlier this year? Don’t miss out on your favorite blogger Monoseanarides’ holiday special.
SARS-CoV-2 is a highly contagious strain of the coronavirus that spreads in multiple different ways. The virus can be spread through small particles or respiratory droplets (ex. aerosols created by the cough, sneeze, speech, and breaths of a Covid-infected patient). Once these particles are in the air, they are inhaled through the mouth or nose and enter the lungs and airways which is believed to be the most common form of infection. Droplet particles that have landed on surfaces can cause the virus to spread by touch. Once someone has touched an infected surface the disease can spread to them by touching their mouth, nose, or eyes. Spread by touch is not a primary way of transmission. When spending time with someone who has not been tested you should not be within 6 feet or 2 arms lengths of the person. Something to look out for during this pandemic is Community Spread. This is a term coined for an area where multiple people are infected with the virus and not everyone knows where the virus was contracted from. To inquire on whether or not there is a local community spread near you contact your local health department’s website. There are still a lot of questions regarding the spread of the SARS-CoV-2 virus including whether or not warm weather slows down the spread of the virus, and cold weather periods are where the virus spreads most like the flu virus? There is still a lot of research to be done on the virus and there is no permanent answer, but it is safe to assume that cases will start to spike again during the winter because that is when sicknesses like the flu spread best. Another question frequently asked is whether or not the virus can be spread through mosquitos and ticks like other illnesses such as the Zika virus or Lyme Disease. As of now there has been no evidence proving that the SARS-CoV-2 virus can be spread from person to person through the bite of a mosquito or a tick.
For all my crazy biology fans like me no need to worry I’m going to explain to you guys how the SARS-CoV-2 virus infects healthy cells. When a SARS-Cov-2 virus enters your body it latches onto one of your healthy cells’ receptors using its spiked protein surface, it usually latches to a healthy cell in the lungs. The viral proteins latch through the ACE2 receptors. The virus then travels down your respiratory tract to your lower airway where the most ACE2 receptors are present. This can cause your lungs to swell, which can make it harder to breathe. These complications can often lead to pneumonia. Once pneumonia is formed patients go into ARDS, however this only occurs in severe cases.
Normally when a virus enters the body the automatic response mechanism used is innate immunity. Innate immunity is a defense activated immediately after infection. Innate Immunity is the first and second lines of defense because it is a rapid response. After the innate immunity is activated the adaptive immunity is activated. This response is slower because its job is to fight off any extra infected cells and memorize the virus so that the body is prepared for another infection. It has been seen with the SARS-CoV-2 virus (usually in older people) that cytokine storms occur when parts of the immune system overwork or works harder than other parts of the immune system.
