Responses to drugs vary significantly from person to person. There are many factors that influence how a person will respond to a particular drug. One important factor is age. In which of the following age groups are people most likely to have problems with drug responses?

Pathways of exposure
When a pathogen enters our body, dendritic cells play a key role in the organization of the immune response. Their function is to patrol the body and capture invading infectious agents. Under normal conditions, once dendritic cells have captured pathogens such as the Human Immunodeficiency Virus (HIV), the cells mature and are able to degrade them and present them to their main target: CD4+ T cells, which then generate specific antibodies against the invading agent. The new discovery, however, demonstrates how HIV can enter without being degraded and infect dendritic cells, escaping the usual pathogen degradation route and also the classical viral entry mechanism used by other viruses.
The study also demonstrates that exosomes and HIV accumulate in the same intracellular compartment or vesicle, and that their route of transmission from this intracellular compartment to CD4+ T lymphocytes also has strong similarities.
There are pages that contain viruses that install themselves in our computer. They are presented through messages that ask us to install a plugin to visualize the content, advertising or pop-up windows with gifts announcing that you have won a prize… etc. All these messages are nothing more than virus techniques to infect your computer.
In the case of e-mails, viruses can be camouflaged in the mail received or be present in the attached files, since they have macros (a set of instructions that are created for a program to carry out automatically and sequentially). Viral code (malicious code) can be inserted into these instructions.
External devices can contain executables that, when connected to our computer, encrypt, infect or attack our computer. In this regard, we must be very clear about where the external device comes from and whether we can trust the person who provides it to us.
Social networks are also a source of viruses, either by direct message where, for example, an unknown user tells us about a photograph in which you have been tagged with a link to the virus in question, or through publications that attract our attention and turn out to be links to malicious websites or with viruses that attack the computer or mobile device.
Routes of entry of contaminants into the body
In the current context, Mexican citizens are advised to take the necessary preventive measures in case of international travel, as well as to have medical insurance during their stay abroad.
If you are abroad and present symptoms of respiratory disease, contact the health authorities of the place where you are. If you need information or assistance, contact the appropriate Mexican Embassy or Consulate.
Mexico has not adopted restrictions for the entry and return of Mexican nationals from other countries by air. Personnel from the Ministry of Health are at the points of entry to the country to attend to persons presenting symptoms associated with the coronavirus and to take the corresponding measures.
