ClassX Video Lessons Youtube Channel Science Time Coronavirus Update March – What Can You Do to Protect Yourself?
The coronavirus, also known as COVID-19, is spreading quickly around the world. The World Health Organization (WHO) has called it a pandemic. This means it’s a new disease that people don’t have immunity to, and it’s spreading more than expected. While the situation in China is improving, Europe, especially Italy, is facing a big challenge. Italy has put the whole country on lockdown to slow down the virus.
The coronavirus spreads in a way similar to the flu. When an infected person coughs or sneezes, tiny droplets containing the virus are released into the air. These droplets can land on surfaces and objects. If you touch these surfaces and then touch your face, you might get infected. You can also catch the virus by breathing in droplets if you’re close to someone who is sick.
On average, one infected person can spread the virus to two or three others. A study by the Bill & Melinda Gates Foundation found that the virus can spread even if the infected person doesn’t show any symptoms. This was seen on the Diamond Princess cruise ship, where many people tested positive without feeling sick.
Anyone can get the coronavirus, but older people and those with health issues like heart disease, diabetes, or lung problems are more likely to get seriously ill. Initially, the WHO estimated a 2% death rate, but now it’s around 3.4%. This means that out of 100 people who get the virus, about 3 or 4 might die. This number could change as we learn more about the virus.
The best way to protect yourself is to wash your hands often with soap and water or use a hand sanitizer with alcohol. The virus can live on surfaces for a few hours to days, but it doesn’t last long when moved to different conditions. If you think a surface might be contaminated, clean it with a disinfectant and wash your hands afterward.
Face masks can help, but they work best when combined with regular hand washing. Regular surgical masks don’t fully protect you from the virus. A special mask called an N95 respirator is better, but it’s not recommended for everyone. The WHO suggests that people who are sick should wear masks to protect others.
If there’s an outbreak in your area, try to stay home as much as possible to avoid getting exposed to the virus.
Remember, staying informed and following health guidelines are key to keeping yourself and others safe during this pandemic.
Research how the coronavirus spreads and compare it to other viruses like the flu. Create a short presentation to share with the class, explaining the similarities and differences in transmission methods. Use visuals to make your presentation engaging.
Conduct an experiment to demonstrate the effectiveness of handwashing. Use glitter or a similar substance to represent germs. Apply it to your hands, then wash them using different methods (water only, soap and water, hand sanitizer). Observe and record which method removes the most “germs.”
Design a poster that encourages people to follow health guidelines to prevent the spread of COVID-19. Include tips such as washing hands, wearing masks, and maintaining social distance. Use creative graphics and clear messages to make your poster informative and eye-catching.
Prepare a set of questions and conduct a virtual interview with a health professional about COVID-19. Ask about their experiences, the challenges they face, and the importance of public health measures. Share your findings with the class in a written report or video.
Participate in a simulation game where you play the role of a public health official responding to a pandemic. Make decisions on resource allocation, public health messaging, and lockdown measures. Reflect on the outcomes and discuss what strategies were most effective in controlling the virus spread.

[Music] The coronavirus is rapidly spreading across the globe at an exponential rate, and the World Health Organization has officially labeled it a pandemic. A pandemic is declared when a new disease, for which people do not have immunity, spreads around the world beyond expectations. Attention has shifted from China, where the spread appears to slow down, to Europe, where Italy has become the hardest-hit country. The number of infections in Italy has surpassed five digits. To slow the spread of the coronavirus, the Italian government has placed the entire country in lockdown.
So, how do you get infected with the coronavirus? Who is most vulnerable, and what can you do to avoid infection? The way the coronavirus spreads is similar to the flu. When someone who has been infected coughs or sneezes, they release droplets of infected fluid. Most of these droplets fall on nearby surfaces and objects. People can catch the coronavirus by touching contaminated surfaces or objects and then touching their eyes, nose, or mouth. If they are standing within one meter of a person with the virus, they can catch it by breathing in droplets expelled by them.
The average infected person spreads the disease to two or three more. However, according to a study from the Bill & Melinda Gates Foundation, what makes the coronavirus spread so effectively is that it can also be transmitted by people who are asymptomatic or not showing symptoms yet. Asymptomatic cases were even found on the Diamond Princess cruise ship, where a significant number of people tested positive but showed no symptoms. How often asymptomatic transmission is occurring isn’t clear yet.
People of all ages can be affected by the coronavirus, but older individuals and those with pre-existing medical conditions, such as cardiovascular disease, diabetes, and chronic respiratory disease, appear to be more vulnerable to becoming severely ill. Initially, the World Health Organization mentioned a 2% mortality rate; however, as of this month, globally around 3.4% of reported coronavirus cases have resulted in death. This number can change in the future, and the percentage shown represents the risk of dying if infected by the virus.
The most effective way to protect yourself against the coronavirus is by frequently cleaning your hands with an alcohol-based hand rub or washing them with soap and water. Although the virus can stay on surfaces for a few hours to several days, it is unlikely to persist after being moved and exposed to different conditions and temperatures. If you think a surface may be contaminated, use a disinfectant to clean it after touching it, and then clean your hands.
What about face masks? Can wearing a medical face mask protect you against the coronavirus? Masks are effective only when used in combination with frequent hand cleaning. According to Dr. William Schaffner, an infectious disease specialist, regular surgical face masks do not protect you from the virus. A more specialized mask, known as an N95 respirator, offers better protection; however, they are not recommended for public use. The World Health Organization also points out that people sick with the coronavirus should wear face masks to reduce the risk of infection to those around them.
During a coronavirus outbreak in your community, stay home as much as possible to further reduce your risk of exposure.
