Saltex Pharma have worked with a number of global Manufacturers in recent projects including Academic institutions to understand the effects of COVID-19 on varying populations across the globe.

Projects have included:

  • Improved testing of the Virus in 3rd world countries
  • Providing access to novel methods of testing for COVID-19
  • Implementation of local strategies in the fight against COVID-19
  • Advising Ethnic minority groups (due to their greater susceptibility to the virus) on how to best combat this within their communities.

For information we have provided the common Questions surrounding COVID-19 as described by WHO

How does COVID-19 spread between people?

COVID-19 is caused by the SARS-CoV-2 virus, which spreads between people, mainly when an infected person is in close contact with another person.

The virus can spread from an infected person’s mouth or nose in small liquid particles when they cough, sneeze, speak, sing or breathe heavily. These liquid particles are different sizes, ranging from larger ‘respiratory droplets’ to smaller ‘aerosols’.

Other people can catch COVID-19 when the virus gets into their mouth, nose or eyes, which is more likely to happen when people are in direct or close contact (less than 1 metre apart) with an infected person.

Current evidence suggests that the main way the virus spreads is by respiratory droplets among people who are in close contact with each other.

Aerosol transmission can occur in specific settings, particularly in indoor, crowded and inadequately ventilated spaces, where infected person(s) spend long periods of time with others, such as restaurants, choir practices, fitness classes, nightclubs, offices and/or places of worship. More studies are underway to better understand the conditions in which aerosol transmission is occurring outside of medical facilities where specific medical procedures, called aerosol generating procedures, are conducted.

The virus can also spread after infected people sneeze, cough on, or touch surfaces, or objects, such as tables, doorknobs and handrails. Other people may become infected by touching these contaminated surfaces, then touching their eyes, noses or mouths without having cleaned their hands first.

Find out more about the science about how the SARS-CoV-2 virus infects the body and how our body’s immune system reacts by watching or reading this interview with WHO’s technical lead for COVID-19, Dr Maria Van Kerkhove.

When do infected people transmit the virus?

Whether or not they have symptoms, infected people can be contagious and the virus can spread from them to other people.

Laboratory data suggests that infected people appear to be most infectious just before they develop symptoms (namely 2 days before they develop symptoms) and early in their illness. People who develop severe disease can be infectious for longer.

While someone who never develops symptoms can pass the virus to others, it is still not clear how frequently this occurs and more research is needed in this area.

What is the difference between people who are asymptomatic or pre-symptomatic? Don’t they both mean someone without symptoms?

Both terms refer to people who do not have symptoms. The difference is that ‘asymptomatic’ refers to people who are infected but never develop any symptoms, while ‘pre-symptomatic’ refers to infected people who have not yet developed symptoms but go on to develop symptoms later. .

Are there certain settings where COVID-19 can spread more easily?

Any situation in which people are in close proximity to one another for long periods of time increases the risk of transmission. Indoor locations, especially settings where there is poor or no ventilation, are riskier than outdoor locations.

Transmission can occur more easily in the “Three C’s”:

  • Crowded places with many people nearby;
  • Close-contact settings, especially where people have conversations very near each other;
  • Confined and enclosed spaces with poor ventilation. 

The risk of COVID-19 spreading is higher in places where these “3Cs” overlap.

In health facilities, some medical procedures, called aerosol generating procedures, can produce very small droplets (called ‘droplet nuclei’ or ‘aerosols’) that can stay suspended in the air for longer periods of time. This is why health workers performing these procedures take specific airborne protection measures, including using appropriate personal protective equipment, including respirators, and why visitors are not permitted in areas in which these procedures are being performed.

How can I reduce my risk of getting COVID-19?

To limit the risks of getting COVID-19 follow these basic precautions:

  • Follow local guidance. Check to see what national, regional and local authorities are advising so you have the most relevant information for where you are.
  • Stay at least 1 metre away from others, even if they don’t appear to be sick.
  • Wear a mask, especially when you can’t physically distance.
  • Manage your risks by thinking about location and setting of the event, proximity to others and time you will be at the event. In other words, consider where you are going, how close you will be to other people and how long you will be there. Avoid crowded places and events, poorly ventilated indoor locations and prolonged contact with others.
  • Open windows when indoors to increase the amount of outdoor air.
  • Avoid touching surfaces, especially in public settings, because someone with COVID-19 could have touched them before. Clean surfaces regularly with standard disinfectants.
  • Frequently clean your hands with soap and water, or an alcohol-based hand rub. If you can, carry alcohol-based rub with you and use it often.
  • Cover your coughs and sneezes with a bent elbow or tissue, throwing used tissues into a closed bin right away. Then wash your hands or use an alcohol-based hand rub.

In addition to the above, please find the below information about the various types of tests that are available around the world. Should you require more detail around each of these test types, please contact us

Lab Based Tests


A diagnostic test can show if you have an active coronavirus infection and should take steps to quarantine or isolate yourself from others. Currently there are two types of diagnostic tests– molecular tests, such as RT-PCR tests, that detect the virus’s genetic material


An antibody test looks for antibodies that are made by your immune system in response to a threat, such as a specific virus. Antibodies can help fight infections. Antibodies can take several days or weeks to develop after you have an infection and may stay in your blood for several weeks or more after recovery.

Point of Care Testing

Diagnostic Tests


Rapid, point-of-care diagnostic tests use a mucus sample from the nose or throat but can be analyzed at the doctor’s office or clinic where the sample is collected and results may be available in minutes. These may be molecular or antigen tests.


Combination tests can test for the flu and the coronavirus at the same time. Some can test for many different types of respiratory viruses, including the one that causes COVID-19.


At-home collection tests, available only by prescription from a doctor, allow the patient to collect the sample at home and send it directly to the lab for analysis. Some at-home collection tests have a health care provider oversee the sample collection by video with the patient.


Saliva tests allow a patient to spit into a tube rather than get their nose or throat swabbed. Saliva tests may be more comfortable for some people and may be safer for health care workers who can be farther away during the sample collection.

Serology Tests


Antibody tests may provide quick results, but should not be used to diagnose an active infection. Antibody tests only detect antibodies the immune system develops in response to the virus, not the virus itself. It can take days to several weeks to develop enough antibodies to be detected in a test.

Saltex Pharma has facilitated many antibody tests to new markets worldwide
