Scientists from all over the world are trying to find a cure for the coronavirus. At the same time, among the negative consequences of the coronavirus in some countries, outbreaks of a dangerous disease—mucormycosis, or the so-called "black mold", are recorded.
In addition, an investigation into the origin of the coronavirus that caused the pandemic has come to an end in the United States. In particular, American intelligence has stated that COVID-19 is of laboratory origin. 
has compiled the most interesting news about the fight against coronavirus in the world.
U.S. report on coronavirus origins
According to a classified U.S. intelligence report at disposal of The Wall Street Journal, three Chinese scientists from the Wuhan Institute of Virology were gravely ill and had had symptoms of coronavirus in November 2019 even before the news of COVID-19 emerged.
This may indicate that the origin of the coronavirus is artificial.
However, US President Joe Biden said that American intelligence did not have enough information to find out exactly where the spread of the coronavirus had begun. Biden instructed intelligence agencies to redouble efforts to study the data and prepare a new report within 90 days.
WHO also does not rule out the laboratory origin of the coronavirus. However, this version remains unproven, despite the report of American intelligence.
Outbreaks of "black mold"
Since the beginning of May, scientists have begun to record cases of mucormycosis in India in people who have had coronavirus. Subsequently, outbreaks of this disease were recorded in Iran, Mexico, and Uruguay.
Immunocompromised people are more susceptible to infection. In particular, this applies to patients with coronavirus, diabetes mellitus, those taking steroids and those who suffer from other concomitant diseases, in particular cancer, as well as persons after organ transplantation.
Sick people are especially susceptible because their immune system is not only affected by the virus—medications for treatment can also suppress the immune response.
In addition, patients receiving oxygen support in intensive care units may have humidifiers in the ward increasing exposure to moisture, and that can increase their susceptibility to fungal infections.
Also, the humid climate of the country can affect the spread of the fungus.
Although mucormycosis is known as "black mold", the adjective is not about the color of the fungus, but about what it causes—tissue necrosis.
In southern Iraq, doctors have recorded at least two deaths from mucormycosis. Another two cases were recorded in Mexico and Uruguay. All cases of the disease were recorded after patients had been ill with coronavirus.
WHO registered CoronaVac vaccine
The World Health Organization has approved the CoronaVac coronavirus vaccine from the Chinese company Sinovac for emergency use. Inoculations with this vaccine can be given to persons over 18 years old. Vaccination involves receiving two doses of the drug with an interval of two to four weeks.
According to the results of the WHO inspection, the vaccine is 51% effective in symptomatic treatment, while at the same time it is 100% effective in preventing severe forms of coronavirus and hospitalization.
CoronaVac can now be added to the global COVAX initiative, accelerating the worldwide certification of this vaccine.
In addition, Ukrainians who have been vaccinated with two doses of CoronaVac will be able to obtain international vaccination passports. Recall that Ukraine signed contracts for the supply of 1.9 million doses of this drug.
Mass vaccination centers in Ukraine
Mass vaccination centers were opened in Kyiv, Lviv, and Odesa on May 29 and 30. They vaccinate against coronavirus those who have registered in the Diia application or through the contact center of the Ministry of Health and are in the queue for vaccination.
In two days of work, almost 3,500 people were vaccinated in the capital's center, and more than a thousand in Lviv.
The vaccination center in Kyiv operates on the basis of the International Exhibition Center, in Lviv—on the basis of the Arena Lviv stadium, and in Odesa—on the basis of the National University "Odessa Law Academy'' stadium.
At the same time, it is not possible to choose a drug for vaccination in such centers. Vaccination is carried out with those vaccines that are available. For now, vaccination centers inoculate people with CoronaVac.
List of vaccines approved by WHO
The WHO recently approved the seventh coronavirus vaccine, the Chinese vaccine CoronaVac. Earlier, the organization approved the Korean and Indian versions of the AstraZeneca vaccine that were purchased by Ukraine.
In Ukraine, people are usually vaccinated with the CoronaVac of the Chinese company Sinovac Biotech, CoviShield—the Indian analogue of AstraZeneca, and Pfizer.
In general, WHO has approved the following vaccines:
