For 80% of people, coronavirus infection is safe. But knowing when to ask for help is worth everything.
Scientists still do not fully understand what SARS ‑ CoV ‑ 2 coronavirus is and how to deal with COVID ‑ 19, the disease that it causes. But it is already clear how exactly in most cases the ailment develops and in what time period its symptoms occur.
Happy Worthy Life leads timeline the average COVID ‑ 19 – by day from the moment of infection. Do not miss important signs of the disease.
An accurate diagnosis can only be made by a doctor and only on the basis of a test. If you have coronavirus symptoms, first contact your GP or call the hotline at 8 800 20‑00‑112 and follow the instructions .
Infection. The risk of catching the virus is above all somewhere in the crowd, at the checkout counter of a supermarket, in a subway car. Or, for example, in personal contact with a person who recently returned from abroad. SARS ‑ CoV ‑ 2 is transmitted primarily by airborne droplets, and close contact (less than 2 meters away) is the most common route of infection.
It may take 2 to 14 days for the first symptoms to appear. In some cases, the incubation period lasts up to 27 days – the term, presumably, depends on the characteristics of a particular person. However, such a long period is extremely rare.
Most often, COVID ‑ 19 makes itself felt in about 5 days after infection.
We proceed from this figure in further calculations.
Digestive symptoms. Although WHO considers they are uncharacteristic for coronavirus (after all, the infection affects mainly the respiratory tract), there is evidence that every second sick person has stomach problems.
In most cases, patients complain of:
- loss of appetite
- abdominal pain.
Please note: these symptoms are not yet a sign of illness. The stomach can hurt for a variety of reasons . Another thing is if, against the background of digestive disorders, signs characteristic of coronavirus infection appear.
There are key symptoms of coronavirus. In the vast majority of cases, there are three:
- Temperature increase up to about 38–39 ° С.
- Dry cough.
Symptoms are similar to those that appear with the flu . And this is one of the main problems in the diagnosis of COVID ‑ 19. There are no characteristic symptoms that would immediately distinguish coronavirus infection from normal seasonal SARS. This is not to say: “If you have a runny nose, this is definitely not a coronavirus.” Or: “If you have a dry cough, but the temperature is not high, this is exactly the usual SARS.”
Key symptoms of coronavirus may be accompanied (or may not be accompanied) by additional:
- runny nose;
- stuffy nose;
- sore throat;
- wet cough with sputum;
- muscle and joint pain .
In some cases, COVID ‑ 19 is completely easy and almost asymptomatic. And sometimes it manifests itself with non-standard signs. For example, complete or partial loss of smell – anosmia. This is reported experts of the British Association of Otorhinolaryngology.
Be that as it may, with a mild course of COVID ‑ 19, approximately 4–7 days after the onset of symptoms, the patient becomes better. The man is recovering. Such lucky statistics – 80% of the total number of cases.
But in 20% of all cases, the process is difficult. And the disease manifests itself with additional symptoms.
- severe shortness of breath, difficulty in breathing;
- painful, constricting sensation in the chest;
- extreme weakness, blurred consciousness;
- bluish lips, pallor.
Such symptoms suggest that severe pneumonia develops . The lungs are damaged and the person experiences oxygen starvation. Urgent hospitalization is required.
Treatment of such patients may be delayed for a week or two and require oxygen therapy (inhalation of air with high oxygen content).
Three quarters of patients who have developed viral pneumonia are slowly starting to recover.
But a quarter (up to 6% of the total number of cases) develop a dangerous complication – acute respiratory distress syndrome. In this case, the immune cells that must fight the infection inside the lungs go crazy and begin to attack healthy tissue, including.
The patient’s condition deteriorates sharply, he loses the ability to breathe on his own and needs to be connected to a ventilator.
Mechanical ventilation is an extreme measure. Which, moreover, does not always help: half of the patients connected to the device still die. In most cases, this occurs on the 14–19th day after infection .
But it helps some mechanical ventilation. The condition of the sick is improving. True, lung injuries and the disorders caused by them – respiratory, cardiovascular, neurological and others – do not go away.
- American raises a record nearly 50,000 Covid-19 cases in a day
The number of new Covid-19 infections in the US on July 1 increased to nearly 50,000. This is the number of Covid-19 infections in a record high day of the world’s top pandemic hot spot.
Leading infectious disease expert of the US government , Dr. Anthony Fauci, has warned that the number of cases of Covid-19 a day can reach 100,000 if the Americans do not agree to take necessary preventive measures. For example, such as wearing mask if unable to adhere to social distancing
“We cannot focus only on areas where the number of cases is increasing. This will put the whole country at risk, ”said Fauci, director of the National Institute of Allergy and Infectious Diseases.
During the first week of June, the US recorded an average of 22,000 cases of Covid-19 each day. A month later, in the Solar Belt, an area across the West and Southwestern of the United States, the Covid-19 hot spots emerged. In the last week of June, the number of infections per day nearly doubled, with 42,000.
Brazil is the only country to report more than 50,000 cases of Covid-19 in a single day. On June 30, the US announced at least 49,286 cases.
More than half the daily new infections of the US come from Arizona, California, Florida and Texas, home to 30% of the nation’s population. These 4 states and 10 other US states had double the number of new infections in June.
This increase is in part related to Memorial Day party parties in late May. US health professionals are concerned about the National Day of July 4 this week, when Americans often flock to beaches and Camping area to see fireworks.
- WHO updates mask recommendations
Now they are advised to wear not only sick.
WHO Director-General Tedros Hebreyusus, at a new briefing on COVID-19, announced new recommendations for the prevention of coronavirus. Here are the main points:
- Doctors and other medical staff should always wear masks, regardless of whether they work with infected coronavirus infections or not.
- People over 60 years of age, as well as those who have chronic diseases, are advised to wear masks wherever it is impossible to maintain physical distance.
- The governments of the countries should encourage the wearing of masks in any places where it is impossible to maintain physical distance, especially for public transport and shops.
- Those with symptoms similar to coronavirus infection should stay at home. All who contacted him should be quarantined.
- If a sick person or someone who has contacted him needs to leave the house, he must wear a mask.
- WHO considers masks to be of high quality, which consist of three layers of different materials or more.
Previously, the WHO spoke only about the need to wear masks for patients who were ill, because there was insufficient data (apart from clinical studies, which many experts consider to be of little relevance to real life).
- WHO recorded 106,000 new infections globally in 24 hours
The WHO recorded 106,000 infections in 24 hours, a record day since the outbreak, with two-thirds of these cases recorded in only 4 countries.
Tedros Adhanom-Ghebreyesus, Director General of the World Health Organization (WHO), said on May 20 that the number of coronavirus infections reported to the agency in the past 24 hours has been higher than at any time since outbreaks, according to CNN.
“We still have a long way to go in this pandemic,” Tedros said at a news conference in Geneva, Switzerland. “In the past 24 hours, 106,000 cases have been reported to WHO – the highest daily level since the outbreak.”
“About two-thirds of these cases have been reported in only four countries,” he added.
According to WHO epidemiologist Maria Van Kerkhove, confirming with CNN via email, these four countries are the US , Russia, Brazil and India.
It should be noted that there may be a delay in reporting the number of cases at various points in the process, so the above date record does not mean that these 106,000 people were infected, tested or statistically counted in the last 24 hours.
According to the constantly updated data of John Hopkins University, the world has recorded nearly 5 million cases of coronavirus, of which more than 326,000 people have died. The United States remains the leading country in both cases – more than 1.5 million, and deaths – more than 93,000.
Notably, Russia has recently become the second country in the number of cases – more than 308,000, although only a few weeks earlier did not even make the top 20 of the list. Brazil also climbed rapidly in the ranking, ranking third in the number of cases – more than 271,000.
Russia is ranked second in terms of deaths – more than 35,000, followed by Italy – more than 32,000, France – more than 28,000, Spain – more than 27,000.
- Brazil has most deadly day of epidemic, patients do not have enough breathing machines
Brazil recorded the highest number of Covid-19 deaths since the outbreak, as coronavirus continues to exert a heavy influence across South America.
According to the Guardian , the number of deaths due to the coronavirus recorded on May 19 in Brazil is 1,179, the highest number of deaths per day since the outbreak in the country. Earlier, the highest number of deaths in 24 hours due to the disease was recorded on 12/5 with 881 cases.
Brazil has also officially overtaken the UK in the number of cases to become the 3rd largest outbreak in the world. The South American country has recorded 271,628 cases positive for coronavirus, an increase of 17,408 cases compared to the previous 24 hours.
Other South American countries also noted the heavy impact of Covid-19. As in Brazil, many cities in South America report deaths due to don’t have enought breathing machine.
Chile is facing the risk of collapse of public health system due to overload. More than 90% of the intensive care beds in Chile’s capital Santiago have been mobilized to treat Covid-19 patients. The city cemetery had to dig 1,000 emergency graves urgently to prepare for the “wave of death” approaching.
In the Peruvian capital Lima, cases of Covid-19 infections account for 80% of the intensive care beds. “We are in a bad situation, this is a war,” said Pilar Mazzetti, who heads the Peruvian government’s anti-Covid-19 task force.
Public health organization Pan American Health said there was growing concern about the risk of virus spreading in the border areas between Brazil and Colombia and Peru. The organization calls on regional authorities to step up measures to protect vulnerable groups such as aboriginal people, the poor and ethnic minorities.
In Africa, the number of Covid-19 infections across the continent has exceeded 90,000 cases, with a total of 2,907 deaths. South Africa is the country most affected by the disease with more than 17,200 cases, of which 312 cases have died. The number of Covid-19 infections in Africa has been described as “stabilizing” in recent days.
- Covid-19 caused infections of the intestines, kidneys and many other organs
Pneumonia virus can spread throughout the body, to the lungs, throat, heart, liver, brain, kidneys and intestines.
Published on May 13 in the journal Nature Medicine , a research team at the University of Hong Kong said the pneumonia virus can attack many different parts of the body.
This finding helps explain why the symptoms of people infected with Covid-19 appear in many parts of the respiratory system. This includes blood clots that cause strokes in young people, blockage of the dialysis system, headaches and even kidney failure.
Covid-19 is classified as a respiratory virus, spread through respiratory droplets, but it can still cause diarrhea and many other digestive symptoms. The researchers also found virus traces in the faeces of patients with Covid-19. This evidence shows that it can be transmitted through waste.
Researcher Jie Zhou and colleagues at Hong Kong University tried to find out how the SARS-CoV-2 virus can thrive in the gut. In laboratory samples in both bats and humans, the virus invaded many internal organs. Viruses not only live but also grow exponentially.
“The human intestinal tract may be the infectious route of SARS-CoV-2,” the research team said.
“A 68 year old female patient had a fever, sore throat, high cough and diarrhea after being admitted to the hospital at Princess Margaret Hospital. We isolated the infectious virus from her stool sample. Here we have demonstrated that the virus replicates in organic matter in the intestinal tract, ”Zhou said.
In addition, another team at the University Medical Center Hamburg-Eppendorf (Germany) also performed autopsies of 27 patients who died of Covid-19. They found traces of the virus in many parts of the patient’s body.
The pneumonia virus is mainly active in the kidney, which explains the rate of kidney damage is usually higher than other parts in Covid-19 patients.
Infection with SARS-CoV-2 virus can make underlying diseases worse. Conversely, people with heart disease, diabetes and especially kidney disease will also be more vulnerable to the virus because of the lower ability of self-healing than healthy people.
