US reopens borders for fully vaccinated travelers
Latest on COVID – 19
Borders
Beginning November 1, the United States will reopen the borders of Mexico and Canada for fully vaccinated individuals.
Fully vaccinated foreign travelers, who come to visit friends or family, may enter through customs points.
Commercial trucks, students, and others who must regularly cross the border must also be fully immunized.
Customs officers will ask travelers about their vaccination status, and may eventually send them to a second check or to show proof of immunization.
Sister border cities, through which thousands of their residents cross every day, have been particularly affected: many buy food, seek care doctors or even visit relatives in the city of the neighboring country.
Johnson & Johnson
Pharmaceutical Johnson & Johnson applied to the United States Food and Drug Administration (FDA) to approve its single-dose vaccine as a vaccine also for reinforcement.
On September, the pharmaceutical company had announced that its COVID vaccine booster is 94% effective if given two months after the first dose.
J&J said that even a booster six months after the first dose raises antibodies at a very high level of protection.
If the FDA authorizes this reinforcement, it would enable the pharmaceutical company to administer them in the 14. 8 million people who have already received the single dose.
Infant Doses
Pharmaceutical Pfizer said its vaccine works in children ages 5 to 11 years, and that will present the data of studies to achieve the OK.
Pfizer said the vaccine is safe and effective, with the potential for the same side effects.
MU variant expands
A new variant of the coronavirus that causes COVID – 19, called Mu, continues to expand and begins to worry more to epidemiologists.
This variant arose in Colombia, where it represents close to 35% of the cases. In Ecuador it represents more than 11% of the cases. Cases have already been reported in the United States and their spread in the United Kingdom is under investigation.
The World Health Organization (WHO) reports that it is present in at least 40 countries.
Controversy, masks and schools
While millions of students have returned to classrooms in the United States, school districts in some areas of the country face harsh controversies.
In some states, such as Maryland, the wearing of masks is mandatory in school buildings. But in others, like Texas, the state has banned these mandates, as they have challenged some systems.
The result is schools where some children go to school with their masks and others do not.
Multiple COVID outbreaks have already been recorded within days of starting the school year in most of the country.

What are coronaviruses
Coronaviruses (CoV) are a broad family of viruses that can cause various conditions, from the common cold to more serious illnesses, such as the Middle East respiratory syndrome coronavirus (MERS-CoV) and the severe acute respiratory syndrome coronavirus (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 have shown that SARS-CoV was transmitted from the civet to humans and that MERS-CoV has been transmitted from dromedary to humans. In addition, it is known that there are other coronaviruses circulating among animals, which have not yet infected humans.
Characteristic symptoms
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 your arm, not your hand). Masks should be used, especially indoors.
Contact should also be avoided Close to anyone with signs of a respiratory condition, such as coughing or sneezing. Comply with 6-foot (two-meter) social distancing and stay home if symptoms appear.
