COVID-19 Pandemic Has Increased the Demand for Nasopharyngeal Swab

 


A nasopharyngeal swab is a method for collecting specimens for diagnostic testing of nasal secretions from the back of the nose and throat. The sample is then analyzed for the presence of organisms or other diagnostic markers for the disease. A nasopharyngeal swab is widely used in suspected cases of influenza, diphtheria, cough, and a variety of diseases caused by the coronavirus family of viruses, such as severe acute respiratory syndrome (SARS), Middle East respiratory syndrome (MERS), and COVID-19.

The novel coronavirus (COVID-19) is an infectious disease caused by a newly discovered coronavirus. The novel coronavirus quickly transformed from a local outbreak to a pandemic and has made its way to almost every corner of the world. Testing for COVID-19 involves placing a 6-inch long swab in the cavity between the nose and throat for 15 seconds and rotating it several times. The swab is then put into a container and sent to a laboratory for testing. In April 2020, the United States Food and Drug Association (FDA) announced its approval for a broader range of swabs to be used in the tests. 

To date, in the United States, the virus has infected more than 15.5 million people and killed more than 290,000 people. In the United Kingdom, the virus has infected more than 1.77 million people and killed more than 62,566 people. In Italy, the virus has infected more than 1.77 million people and killed more than 61,739 people. As these are essential for testing COVID-19. The rising number of cases worldwide has stirred the demand for Nasopharyngeal Swabs. As of December 9, 2020, the United States had performed more than 211 million tests for COVID-19, the highest number of any country worldwide.

Increasing Initiatives to Digitalize the Healthcare Sector Is Expected To Boost Demand for Electronic Medical Records

  An electronic medical record (EMR) is essentially a systematized collation of individual patient and family health information in an electronic format. This information is then shared across several health care locations. This will save time, money and provide patients with more comprehensive care. Increasing initiatives to digitalize the healthcare sector is expected to boost demand for EMR. For instance, in November 2019, Germany introduced Digital Supply Act to digitalize healthcare. Under the new legislation, doctors will be able to prescribe digital health apps to patients, which can be reimbursed by the country’s statutory health insurance. There are several advantages to using EMR. The main advantage is that you do not need to wait for the paper records to go through the paper processing before you can use them. Another advantage to electronic medical records is that they allow for greater privacy. Electronic health records allow only the doctor to see these...

Ureteroscopes are highly preferred option over traditional ureteroscopy

Image
  Ureteroscopes are instruments that have been designed to allow doctors (including surgeons) to look inside the reproductive organs. This is done by passing a thin, lightweight tube through the cervix and up to the vagina. Once there, the tube makes a turn inside the uterus and exits via the fallopian tubes. The purpose of this excursion is to look for problems in the uterus or ovaries, which can cause infertility or hormonal imbalance in women. They are able to find many problems that other instruments might miss. One of the most common uses for such device is when doctors make the very first ultrasound images of pregnancy. The Ureteroscope is able to detect whether or not the fetus is progressing normally through the maternal birth canal and is able to help determine the health of the mother's uterus. Doctors also use these devices when they make the first "cavity" ultrasound images of a woman's abdominal cavity, looking for problems that could be c...
