What is coronavirus?
Coronavirus are a family of RNA viruses that most often cause disease in animals, and some of them in humans. In humans, the infection usually proceeds in a mild form with symptoms of acute respiratory viral infections without causing serious complications.
What is COVID-19?
COVID ‑ 19 is an infectious disease caused by a new type of coronavirus that a person is believed to have contracted from animals. The exact source of infection has not yet been established.
How does the virus spread?
- Coughing and sneezing
- With handshake
- Through items
The disease is transmitted through small drops released from the patient’s nose or mouth when coughing or sneezing. These drops fall on objects and surfaces surrounding a person. Other people may become infected by touching such objects or surfaces first and then with their eyes, nose, or mouth.
In addition, infection can occur by inhalation of the small drops that are released when a person coughs or sneezes with COVID ‑ 19. For this reason, it is important to stay away from a sick person at a distance of more than 1 meter. The risk of infection through the air is much lower.

What are the symptoms of COVID ‑ 19?
The main symptoms are:
- Increase in body temperature (in> 90% of cases)
- Cough (dry or with a small amount of sputum) in 80% of cases
- Shortness of breath (in 55% of cases)
- Chest sensation (in> 20% of cases)
Rare symptoms (at the onset of the disease can occur without fever)
- Headaches (8%)
- Hemoptysis (5%)
- Diarrhea (3%)
- Nausea, vomiting
In most people (about 80%), the disease ends in recovery, with no specific therapeutic measures required. In about one in six cases of COVID-19, severe symptoms occur with the development of respiratory failure.
In older people, as well as people with chronic diseases, such as arterial hypertension, heart disease or diabetes, the likelihood of a severe course of the disease is higher.
In the presence of elevated body temperature, coughing and shortness of breath, an ambulance should be urgently called (103 from a mobile phone).
How to protect the elderly?
The main task is to isolate them from crowded places :
- If possible, send your loved ones to the cottage before the summer (there is a likelihood that the epidemic will subside with the arrival of heat, since the virus is unstable under the influence of ultraviolet radiation).
- Stock up on medicines that your loved ones take all the time (from pressure, diabetes, and so on) to prevent them from going to the pharmacy.
- Arrange delivery of food and other necessary things home .
- If you need to visit public places – call a taxi or use your personal transport .
- In case of symptoms of malaise – be sure to call an ambulance (103 from your mobile). In the elderly, viral diseases often go away without temperature and in a more lubricated form, so even try to respond promptly to mild symptoms of SARS.

- 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.
