Most Covid cases of asymptomatic Karachi

Up to 95% of coronavirus cases in Karachi are asymptomatic, and researchers yesterday shed possible light on why Pakistan was able to survive a pandemic.
Coronavirus causes Covid-19 respiratory disease.
A study at the University of Aga Khan (AKU) in Pakistan’s largest city found that more than 9 in 10 people infected with the coronavirus showed no signs of the disease.
Public health professionals have tested 2,000 people from several areas of the vast metropolis of about 20 million.
“95% of people who tested positive for Covid-19 reported not feeling the symptoms of the disease, such as cough, fever, and sore throat,” said study lead investigator Imran Nisar. I told him.
Further research is needed to understand why many cases in Karachi appear to be asymptomatic, researchers say, but could be attributed to the young population of Pakistan. did.
With a median age of just 22 years in the country, coronaviruses are known to unduly affect older people who have previously had health complications.
AKU’s research report, co-created with Dr. Bailey Fosdick and Dr. Daniel Valleymore, international co-workers based in the United States, said: It’s expensive.”
“The percentage of asymptomatic cases in Pakistan is much higher than in developed countries. According to a statement, asymptomatic people do not seek medical treatment in hospitals, which means that hospitals in Pakistan are in Spain or the United Kingdom. It may help explain why you are not in the same tension as.
In addition, the study also suggested that children and adolescents were as likely to be infected with the virus as adults, and men and women were at the same risk of becoming infected with the infectious disease.
The study, which confirmed a sharp increase in the number of Covid-19 cases between April and June of this year, is consistent with the federal national antibody-preservation survey, which shows that the antibody test was conducted in Pakistan. It turns out that 11% of all people have this disease.
Dr. Imran Nisar, an associate professor at AKU, a collaborator in the study, said: “The rapid increase in antibody levels in areas with low numbers of cases indicates that the virus continues to spread unchecked in suboptimal populations.”
With more than 2,000 participants in the first two phases of the study, the researchers are currently conducting a third serologic study and are planning a fourth study in September 2020.
These studies also reflected the overall impact on the coronavirus prevalence of the community by relaxing the coronavirus blockade around Eid al-Adha and during the Muharram march.
“Antibody tests or seropositivity provide a real picture of the burden of Covid-19 because it captures asymptomatic cases that are asymptomatic carriers of Covid-19,” said AKU. Dr. Fyezah Jehan, associate professor and collaborator in the research, said:
“Understanding how, when, and under what circumstances Covid-19 spreads is important for developing effective public health and infection control measures that break the chain of infection.”
The low number of cases in Pakistan compared to other South Asian countries has puzzled public health professionals.
The country has a long history of failing to contain some infectious diseases such as polio, tuberculosis and hepatitis, but successive governments have not funded its health sector for decades. ..
The number of cases has been declining, few viral cases have been seen in the intensive care unit, Pakistan has lifted most of the rest of the restrictions, and schools and colleges will resume next week.
To date, approximately 300,000 cases of infection have been confirmed in Pakistan, with hundreds of new cases recorded daily, but daily deaths are in the single digits.
