Why is Covid-19 so furious in one country slightly in another?

Hundreds of studies worldwide are still underway to find the cause of the unequal Covid-19 attacks in each region and country. The answer to this problem is important because it helps people find the best way to protect themselves and what steps they should take, for how long to avoid Covid-19.

The Dominican Republic has registered 7,600 cases of Covid-19 but the neighboring country: Haiti has only 85 positive cases with the virus.

In Indonesia, more than 800 people died from the disease, but nearby, Malaysia and Singapore recorded only 105 and 17 deaths from the virus, respectively.

Covid-19 has spread to almost every country on earth, but the impact of the disease is clearly uneven. Large cities such as New York (USA), Paris (France) and London (United Kingdom) have been severely affected by the disease, but other cities such as Bangkok (Thailand), Baghdad (Iraq), New Delhi (New Zealand). India), the spread of Covid-19 appears to be still slow.

The New York Times summarized the scientists’ research and gave some basic causes that made Covid-19 influence unevenly across countries.

1. The strength of the young population.

Many countries have significantly reduced the impact of the disease thanks to their young population.

“Studies show that young people often have milder symptoms when they become infected with Covid-19,” said Robert Bollinger, professor of infectious diseases at the Johns Hopkins School of Medicine (USA).

As of 3.5, Africa has around 45,000 Covid-19 cases. This is only a very small fraction of the 1.3 billion people on the continent with the youngest population in the world. 69% of the African population is under 25 years old.

In contrast, the average age of Italy, the country with the highest number of Covid-19 deaths in Europe, is 45 years old.

“Young people have a good immune system and often do not have an underlying disease. This helps most young people with Covid-19 show only mild symptoms, “said Josip Car, world expert on population and health at Nanyang University of Technology (Singapore).

In Singapore and Saudi Arabia, the majority of Covid-1 infections are found among migrant workers abroad. People of working age are often young and healthy, even though they have to live in dorms with poor sanitation.

Along with young people, the health foundation is also an important factor in reducing the impact of the disease. People with obesity, diabetes, or high blood pressure can experience severe symptoms when infected with Covid-19.

However, the young population is not the primary cause for a nation to keep Covid-19’s death rate low. A good example is Japan, one of the countries with the oldest population in the world, which has registered almost 500 virus-related deaths.

2. Differences in culture

Cultural factors also play an important role in protecting a nation from disease. In Thailand and India, where relatively low infection rates are supposed to occur, people have a habit of greeting each other from afar, applauding as if praying.

In Korea and Japan, people bow to one another. In some other countries, people wear masks as a healthy habit.

Europe, the United States, and most developed countries often practice sending older people to nursing homes for intensive care. When Covid-19 attacked these facilities, the elders were very vulnerable. About half of all deaths in Europe come from nursing homes.

In some European countries, people have a habit of hugging when they meet. This increases the risk of Covid-19 infection due to close contact.

However, the cause comes from the culture is not entirely convincing. In many Middle Eastern countries, people also have a habit of hugging and shaking hands, but the number of infections is not as high as in Europe, except in Iran.

3. Temperature and light.

Covid-19 seems to spread more strongly in temperate countries, in relatively cold climates such as Italy, the United States, and almost fewer outbreaks in warmer countries, such as Chad or Guyana (South America). ) Other types of influenza viruses are also less infectious in hot, humid climates.

However, according to scientists, it should not be claimed that Covid-19 will be destroyed or rejected by heat or heat.

Some countries with hot and humid climate, such as Brazil, still register a serious outbreak of the disease with 97,100 cases of Covid-19.

“Summer weather may help, but it is unlikely to significantly reduce the rate of spread of the disease,” said Marc Lipsitch, a medical expert at Harvard University in the United States.

“People think: it is so hot here that nothing will happen to you. Some even go out in the sun, arguing that this will protect them from Covid-19. But that is not the case, ”said Dr. Domenica Cevallos, who works in Ecuador, one of the countries with the most Covid-19 deaths in South America (1,371 cases).

4. Implement measures to limit social exposure early and strictly

Countries that implemented the first Covid-19 measures, such as Vietnam and Greece, were able to prevent the outbreak of the disease. This is evidence of the effectiveness of strict social quarantine and isolation measures to prevent Covid-19 from spreading.

In Africa, some countries with extensive experience in treating HIV, drug-resistant tuberculosis and the Ebola virus are aware of the dangers of Covid-19 and respond quickly.

Sierra Leone, an African country, adopted the disease monitoring protocol used in 2014, when Ebola broke out. The Government of Sierra Leone has also established emergency medical centers in every county in the country. More than 14,000 health workers have been recruited. 1,500 employees are involved in monitoring and monitoring the source of the virus’s spread. Sierra Leone has registered only 155 cases of Covid-19.

Uganda, the African nation that once erupted Ebola, quickly isolated travelers from Dubai (UAE city) after the first Covid-19 case was reported. The recognition comes from this country. Another 800 UAE tourists are also being monitored by Uganda.

According to the WHO, orders to block and restrict social contact play an important role in limiting the spread of Covid-19.

5. Luck

Scientists agree that the response to some countries is less affected by Covid-19 than others due to the combination of all these factors. However, it is impossible not to mention another important factor, luck.

Countries with similar cultures and climates, which take similar epidemic measures may also be affected by different Covid-19s. What is common in countries where the Covid-19 outbreak is so strong is that some people infected with Covid-19 appear during crowded events.

Some of Covid-19’s “super contagious” events, such as the case appeared in the New Heavenly Sect (Korea), the Grand Funeral in Albany (USA), Mardi Gras (USA) OR A Ceremony of prayer in Malaysia.

Without these events, the number of Covid-19 infections in those countries would have been much lower.

The Ministry of Health recommends isolation, health surveillance in the prevention of Covid-19: – For close contacts of Covid-19 positive patients: Isolate at the medical center within 14 days and take samples for analysis. – For close contact with Covid-19 positive patients: Quarantine, monitor health at home, place of residence, residence within 14 days and notify local authorities (neighborhoods, communes, cities) and must closely monitor the health situation. If fever, cough, sneeze, runny nose, fatigue, chills, or shortness of breath are found, immediately isolate at the medical facility and take patient samples for testing. – Wear a mask frequently, cover your mouth when coughing or sneezing. – Wash your hands with soap continuously to avoid the risk of spreading the disease to other people. – Share your own travel schedule with medical staff. – Call the information hotline immediately: 19003228 and 19009095.
