After a five-month battle with the new coronavirus, people should all know how dangerous it is,media BGR reported. Sadly, this is not the case, and many people still choose to ignore the risks. As things stand, coVID-19 is so dangerous for two reasons. First, it is easily transmitted and can be transmitted “quietly” through asymptomatic infections. Second, there is no viral treatment or vaccine that can significantly limit its spread or prevent complications, although many drugs show hope.
A new study for patients with COVID-19 further confirms the dangers of the disease, proving that most patients with new coronary pneumonia can be asymptomatic.
The U.S. Centers for Disease Control and Prevention (CDC) said days ago that as many as 35 percent of new coronavirus infections in the United States are asymptomatic. But under the right conditions, the number could be higher. Australian scientists analyzed the coVID-19 cases on a cruise ship from Argentina in mid-March to find that more than 80 per cent of the confirmed cases of COVID-19 on that cruise ship were asymptomatic. At that time, many countries were declaring national emergencies related to the new coronavirus.
The trip was supposed to last 21 days, but some passengers ended up on the ship for 32 days. Of the 217 passengers and crew on board, 128 tested positive. Of these, only 19 per cent had symptoms. This means that 81% of patients have no symptoms. The study clearly shows that confined spaces such as cruise ship cabins provide the perfect conditions for the spread of the new coronavirus, despite the mitigation measures in place.
The study, published in Thorax, explains that as of mid-March, cruise ships were off-charge passengers from any COVID-19 hotspot. The list includes China, Macau, Hong Kong, Taiwan, Japan, South Korea and Iran. Anyone who has been to these areas within three weeks of the cruise is not allowed to board.
The remaining passengers were checked for symptoms and fever and several health stations were set up inside the ship. These passengers are regularly checked for their temperature within a few days of departure. The cruise industry has learned some lessons from the initial outbreak. In mid-February, the Diamond Princess cruise ship docked in Japan and was not allowed to leave the ship because hundreds of passengers tested positive.
The first suspected COVID-19 case occurred eight days after leaving Argentina. A quarantine protocol was subsequently developed, which included the isolation of patients in the cabin and the use of medical surgical masks. Use a full set of personal protective equipment in contact with a fever patient and an N95 mask when in contact with passengers in the cabin.
More and more cases have followed as ships try to dock and return to Argentina. The country was refused entry because of the closure of its borders. The study explained that the ship decided to change course on the third day in response to the fact that several states had issued travel bans. The ship arrived in Uruguay on the 13th day, and six passengers and crew members with fever were tested for COVID-19. The 14th day was negative, but the authorities refused to allow the vessel to dock until a nasal swab test was carried out. By the 20th day, Uruguay’s Ministry of Health had provided tests for all those on board, although several passengers had previously been evacuated due to complications from COVID-19. On the 27th day, one of the two doctors on board had to evacuate after developing hypoxemia or hypoxemia due to infection. All evacuees tested positive for COVID-19.
“The prevalence of COVID-19 on affected cruise ships is likely to be seriously underestimated and strategies need to be developed to assess and monitor all passengers to prevent cluster infections after disembarking,” the researchers said. They also noted that, despite cabin isolation measures, some passengers did not develop symptoms until the 24th day. They also stressed that passengers sharing the same cabin recorded positive and negative results, which may also be a sign that PCR tests are problematic.
