Short answer (3 points):Directions: Read the following passage (in italics), and then write a summary of the key points in your own words. Even though the virus that causes COVID-19 is transmitted through the respiratory system, that’s not all it affects. The virus can cause damage to children, just as it does to adults. There is even a rare but serious associated disease specific to children that we are just beginning to understand. It’s also true that children spread COVID-19. The largest study involving children and transmission is one from from South Korea that traced nearly 60,000 people, and found that children 10 and older transmit the virus at least as well as adults. This shouldn’t be surprising considering our experience with other respiratory infections. How many of us parents have had the experience of becoming sick after our kids pick up colds at school?Some people who support on-time school reopening point to European countries that have had few outbreaks after resuming in-person instruction. However, these countries undertook many safety measures, including enforcing social distancing and implementing regular testing. They also had far lower rates of COVID-19 in the community than we do.There remains a lot that we don't know about COVID-19 and children, but we know that children can become infected, and that they can transmit the virus to others. Let’s stop justifying school reopenings based on false statements. Instead, let’s talk about how we can get widespread, rapid testing into schools, the importance of wearing masks, and the investments we need to make to reduce the density of students in classrooms and improve their physical layout, ventilation and other infrastructure.

Vaccinated children are less likely than unvaccinated children to develop long COVID, the myriad of symptoms that can last for months to years following a SARS-CoV-2 infection. In the United States, COVID-19 vaccines are recommended for children as young as 6 months old. But uptake has been low. For the study, Anna Yousaf, a medical officer at the US Centers for Disease Control and Prevention (CDC) in Atlanta, Georgia, and her colleagues enrolled 1,600 children and collected weekly nasal swabs from them for more than a year to check for the SARS-CoV-2 virus. The team narrowed the study to 622 participants — aged 5 to 17 years — who caught COVID-19; 28 went on to develop long COVID. The researchers then calculated the odds of vaccinated and unvaccinated children experiencing ongoing symptoms.8Mark for ReviewMCQABCWhich one of the following, if true, most seriously invalidates the argument?AThe study defined long COVID as the persistence of symptoms after one month, whereas the World Health Organization describes long COVID as symptoms that last for at least two months.BThe study initially included several broadly defined symptoms that children might experience on a regular basis but excluded sufferers from the final count. CThere has been a lag in reporting of vaccination numbers in the United States and there are likely more vaccinated children than previously suspected. DWeekly nasal swabs are not frequent enough a check to determine the onset of SARS-CoV-2 and to determine whether an individual has the infection or not.

discuss the Origins spread and global impact of covid 19

Young children are particularly vulnerable to infections becausethey have frequent contact with other children.their immune systems are still developing.they are still learning proper hygiene.All of the above

What disease is being described here? It is a serious viral illness that can be fatal if there are complications, and most children are vaccinated against it.
