The latest on COVID-19
After Martin Luther King’s long weekend, the United States surpassed 400,000 deaths from covid.
On the last full day of the Trump administration, on Tuesday 19, it was learned that the nation already had 400,022 victims of the disease caused by the coronavirus, which was known for the first time in December 2019.
In the country, a person dies from covid every 26 seconds. And this disease causes more deaths each week than any other condition – it is ahead of common “killers” like heart disease and cancer.
The pattern of fatalities is the same since the beginning of the pandemic. In the first week of January, 6,000 older adults died in assisted living centers.
30% of deaths occur in long-term care facilities.
The virus continues to kill more Blacks and Native Americans than Caucasians. And people who live in rural areas have a higher risk of dying from covid than those who live in large cities.
A clinical trial in older adults with COVID-19 showed that an early dose of blood plasma from recovered people helps prevent the disease from becoming serious.
Plasma from people who have recovered from COVID-19 contains antibodies against SARS-CoV-2, the coronavirus that causes the disease.
But plasma treatment has had mixed results and has been controversial.
However, some scientists say that the key is when this therapy is administered. And a scientific team from Argentina got an answer.
A team led by Fernando Polack from the INFANT Foundation in Buenos Aires, conducted a clinical trial to evaluate the effect of plasma treatment within 72 hours after the onset of symptoms. Participants included people over the age of 75 and people between 65 and 74 with at least one pre-existing condition such as diabetes.
Participants who received plasma therapy did not suffer from severe forms of COVID, compared with participants who received a placebo.
The study was published in The New England Journal of Medicine.
Vaccine and allergy: what to expect
The Centers for Disease Control and Prevention said that people who have experienced severe reactions to previous vaccines or injectable medications can still receive the Pfizer / BioNTech vaccine for Covid-19, but should discuss the risks with their doctors and be monitored during 30 minutes later.
During a webinar with doctors, CDC officials said patients with a history of severe reactions should take precautions due to two documented cases of anaphylaxis in British health workers who received the Pfizer / BioNTech vaccine.
If people had a previous allergic reaction, they should talk to their doctor to see if it was really caused by an injectable drug and if it was a serious reaction. The specific reaction providers are trying to avoid is anaphylaxis which can cause symptoms such as dizziness, shortness of breath, wheezing, and a rapid heart rate.
Serious allergic reactions to vaccines are extremely rare and were also rare during the Pfizer / BioNTech trial, which excluded people with a history of anaphylaxis. The FDA has published data indicating that 0.63% of the participants who received the vaccine experienced serious adverse reactions, compared with 0.51% of the people who received a placebo.
In Latin America
The International Labor Organization, a United Nations body, said that due to the pandemic, the region has lost 34 million jobs. This consequence of the public health crisis has deepened the already endemic economic crisis in the region, and increased the poverty gap.
Latin America lost 20% of working hours, compared to 11% in the rest of the world.

What are coronaviruses
Coronaviruses (CoVs) are a broad family of viruses that can cause a variety of conditions, from the common cold to more serious illnesses, such as the Middle East respiratory syndrome coronavirus (MERS-CoV) and the one that causes respiratory syndrome. severe acute (SARS-CoV). A new coronavirus is a new strain of coronavirus that has not been found before in humans.
How do you get coronavirus?
Coronaviruses can be transmitted from animals to people (called zoonotic transmission). Studies confirmed that SARS-CoV was transmitted from the civet to humans and that transmission of MERS-CoV from dromedary to humans has occurred. In addition, it is known that there are other coronaviruses circulating among animals, which have not yet infected humans.
These infections usually cause fever and respiratory symptoms (cough and dyspnea or shortness of breath). In the most severe cases, they can cause pneumonia, severe acute respiratory syndrome, kidney failure, and even death.
Also headache and loss of taste and smell.
How to prevent contagion
The usual recommendations to avoid spreading the infection are to wash your hands frequently and cover your mouth and nose when coughing and sneezing (with the arm, not the hand). Masks should be used, especially indoors.
Close contact with anyone with signs of a respiratory condition, such as coughing or sneezing, should also be avoided. Comply with 6-foot (two-meter) social distancing and stay home if symptoms appear.
