Yes. The common cold is a virus that can be passed from one person to another. Many viruses can be passed through the air, or by shaking hands. Some require a more inmate means to transmit, such as kissing or sex acts.
the flu...
probably...
Computer viruses are currently unable to spread to humans.
it isn't spread, it develops from other causes
It is also spread by germs. But orignally this disease can be spread by the cells throughtout the body.
some are flu , HIV , std
Plants have stronger cells walls. And viruses do spread to plants.
Some computer viruses.
Lab technicians are not spreading the flu, if that is what you are suggesting. Viruses are among us at all times in the "wild", they occur naturally, and have from the beginning of time. They don't need any help from humans to spread and mutate and spread again, that's what they do and how they replicate. Viruses are not being created in laboratories and released into the public. They are studied in laboratories so they can be typed and so vaccines can be developed. For that, we should thank the lab technicians and pathologists and not blame them.
Macro viruses
Influenza viruses are classified into four main types: A, B, C, and D. Influenza A viruses are the most common and can infect both humans and animals, often causing seasonal epidemics. Influenza B viruses primarily affect humans and are generally less severe than A viruses, with limited geographical spread. Influenza C causes mild respiratory illness and is not associated with epidemics, while Influenza D primarily affects cattle and is not known to infect humans.
Malaria is transmitted among humans by female mosquitoes of the genus Anopheles.
